  • Novel percutaneous dual-lumen cannula-based right ventricular assist
           device provides effective support for refractory right ventricular failure
           after left ventricular assist device implantation
    • Authors: Salna M; Garan A, Kirtane A, et al.
      Pages: 499 - 506
      Abstract: OBJECTIVESRight heart failure after left ventricular assist device (LVAD) implantation is associated with significant morbidity and mortality. A new generation of percutaneous right ventricular assist devices (RVADs) may mitigate the need for invasive surgical RVAD implantation. The purpose of this study was to evaluate the safety and efficacy of the Protek Duo (TandemLife, Pittsburgh, PA, USA) RVAD in patients who developed severe acute right heart failure in the intensive care unit after LVAD implantation.METHODSThis was a retrospective cohort study of 27 patients who received a Protek Duo after LVAD implantation from January 2016 to March 2019 at our centre. The primary outcome of interest was survival to hospital discharge. Secondary outcomes included procedural success, device-related complications and conversion to a surgical RVAD.RESULTSThe median age of patients was 63 years (interquartile range 58–71), 78% were men and 78% were Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) profile 1 or 2. Patients were on a median of 2 inotropes and 2 pressors prior to Protek Duo insertion. The device successfully implanted on the first attempt in all patients a median of 1 day (interquartile range 1–2) after LVAD implantation and the median duration of support was 11 days (interquartile range 7–16). Device weaning occurred in 86% of patients, with 15% in-hospital mortality. Major complications related to the device included new moderate-to-severe tricuspid regurgitation (36%), haemolysis (14%) and cannula migration (7%). Three patients (11%) required conversion to surgical RVAD. Overall survival to 1 year was 81%.CONCLUSIONSThe use of the Protek Duo as a percutaneous RVAD is a safe and feasible treatment for patients who develop acute right heart failure after LVAD implantation.

  • Clinical study of an outbreak of postoperative mediastinitis caused by
           Serratia marcescens in adult cardiac surgery
    • Authors: Fernández A; Adrio B, Martínez Cereijo J, et al.
      Pages: 523 - 527
      Abstract: OBJECTIVESNosocomial infection caused by Serratia marcescens after cardiac surgery is rare but causes high rates of morbidity and mortality. Knowledge about postoperative mediastinitis due to S. marcescens is limited. The purpose of this work was to study the clinical presentation, management and outcome of an outbreak of postoperative sternal infection due to S. marcescens.METHODSDuring a 7-week period, a total of 54 patients underwent open heart procedures in our hospital. A postoperative wound infection caused by S. marcescens was diagnosed in 10 patients. We performed a clinical study to investigate patient characteristics and outcomes as well as the possible source of the infection.RESULTSThe mean age of the infected patients was 74.5 ± 10 years. Mediastinitis was present in 6 cases, superficial wound infection in 3 and isolated bacteraemia in 1. Purulent exudate through the sternal incision was observed in all infected cases except in 1 patient, who presented only with bacteraemia. Serratia marcescens was isolated from the samples taken from all infected wounds. The mean time elapsed between the operation and the isolation S. marcescens was 5.9 ± 2.4 days. Response to treatment was favourable in all cases except 1, who died. Contamination of the aqueous chlorhexidine solution used to prepare the patients’ skin with S. marcescens was reported. Microbiological studies demonstrated that S. marcescens strains isolated from patients and from the aqueous chlorhexidine solution belonged to the same clone.CONCLUSIONSThe use of an aqueous chlorhexidine solution contaminated with S. marcescens caused an outbreak of postoperative sternal wound infections. The time elapsed between wound contamination and signs of infection was brief, but the systemic inflammatory response and tissue necrosis were limited. Alcohol-based solutions are recommended for the prevention of surgical site infections.

  • Improved method for the catheterization of the right ventricle in a rat
           model of pulmonary artery hypertension
    • Authors: Tontodonati M; Ridley D, Remie R, et al.
      Pages: 535 - 537
      Abstract: Ventricle catheterization in the rat is widely practiced in cardiopulmonary research. The catheters deployed are either fluid filled or solid tip pressure or pressure–volume catheters. The access to the right ventricle is through the right jugular vein, most commonly without direct visualization such as fluoroscopy. Advancement of the catheter tip is aided by visualizing the pressure signals of the monitoring/recording systems used. This approach may present challenges due to various reasons, including the stiffness of new catheters, their dimensions or anatomical changes associated with the animal disease model. In this article, we present a novel approach, which has been optimized, successfully validated surgically and adopted in current projects. It has been shown to improve both the overall quality of the signals recorded and the time to access the right ventricle, thus reducing the overall time of surgery. The method presented in this article is safe, easy to reproduce and does not require additional skills compared to a more ‘standard’ approach.

    • Authors: Hulde N; Zittermann A, Deutsch M, et al.
      Pages: 538 - 540
      Abstract: In cardiac surgical patients, tranexamic acid (TXA) has been associated with an increased risk of convulsive seizure (CS). We aimed to investigate whether in patients undergoing isolated coronary artery bypass grafting (CABG) surgery the use of cardiopulmonary bypass (CPB) impacts the risk of CS. We studied 4198 propensity score matched patients. Patients who underwent CABG surgery without CPB, received a single bolus of 1 g TXA. Patients who underwent CABG with CPB, additionally received a TXA dose of 0.5 g in the CPB prime and an infusion of 0.2 g/h until the end of CPB. The risk of CS in the CPB group and the group without CPB was 0.7% and 0.6%, respectively (risk ratio 1.08, 95% confidence interval 0.51–2.30; P > 0.99). Kidney function was significantly associated with the risk of CS (P = 0.005), the latter being highest in patients with glomerular filtration rates <30 ml/min/1.73 m2 (2.2%) and lowest in those patients with values >60 ml/min/1.73 m2 (0.4%). Our data in patients undergoing isolated CABG indicate no significant effect on CS risk by use of CPB when TXA doses of up to ∼2 g are given. However, caution regarding TXA administration is necessary in patients with renal impairment.

  • Intent-to-cure surgery for small-cell lung cancer in the era of
           contemporary screening and staging methods
    • Authors: Chenesseau J; Bourlard D, Cluzel A, et al.
      Pages: 541 - 545
      Abstract: OBJECTIVESOur goal was to report on the contemporaneous single-centre experience of patients with small-cell lung cancer (SCLC) who had lung resection with curative intent.METHODSBetween 2005 and 2018, 31 patients were operated on for SCLC with curative intent. There were 11 women and 20 men whose ages averaged 63 ± 10 years. The clinical diagnosis was incidental in 16 patients (51.6%). All patients were screened with high-resolution computed tomography, positron emission tomography and brain imaging. Eight patients (25.8%) had invasive mediastinal lymph node staging.RESULTSPreoperative tissue diagnosis was unknown or erroneous in 26 patients (83.9%). Lung resections comprised mainly lobectomies (n = 23; 74.2%). Lymphadenectomies harvested a mean of 16.3 ± 3 lymph nodes, leading to upstaging in 38.7% of the cases. An R0 resection was achieved in 28 patients (90.3%). Pathological analysis disclosed pure small cell histological specimens in 24 patients (77.4%). There were no 90-day deaths. Perioperative platinum-based chemotherapy was performed in 27 patients (87.1%); adjuvant thoracic irradiation, in 7 (50%) of the 14 N+ patients; and prophylactic cranial irradiation, in 8 (29.6%) of the 27 potential candidates. Overall, disease-free and disease-specific survival rates at 5 years were 32.9 ± 10%, 35.2 ± 10% and 44.1 ± 11.3%, respectively.CONCLUSIONSDespite the use of contemporary screening and staging methods, selection of SCLC candidates for surgery remained haphazard, surgery was typically performed in ignorance of the actual histological and adherence to treatment guidelines was inconsistent. Nevertheless, one-third of patients with SCLC who were operated on were cured, even in cases of regional or oligometastatic disease.

  • Safety and reliability of computed tomography-guided lipiodol marking for
           undetectable pulmonary lesions
    • Authors: Ito K; Shimada J, Shimomura M, et al.
      Pages: 546 - 551
      Abstract: OBJECTIVESThis study aimed to evaluate the safety and reliability of percutaneous computed tomography (CT)-guided lipiodol marking for undetectable pulmonary lesions before video-assisted thoracic surgery (VATS).METHODSWe retrospectively analysed the cases of CT-guided lipiodol marking followed by VATS in 9 institutes from May 2006 to March 2018. Lipiodol (0.2–0.5 ml) was percutaneously injected closely adjacent to undetectable pulmonary lesions with computed-tomography guidance. Lipiodol spots were identified using C-arm-shaped fluoroscopy during VATS. We grasped the lipiodol spots, including the target lesions, with ring-shaped forceps and resected them.RESULTSOf 1182 lesions, 1181 (99.9%) were successfully marked. In 1 case, the injected lipiodol diffused, and no spot was created. Of the 1181 lesions, 1179 (99.8%) were successfully resected with intraoperative fluoroscopy. Two lipiodol spots were not detected because of the lipiodol distribution during the division of pleural adhesions. The mean lesion size was 9.1 mm (range 1–48 mm). The mean distance from the pleural surface was 10.2 mm (range 0–43 mm). Lipiodol marking-induced pneumothorax occurred in 495 (57.1%) of 867 cases. Of these, chest drainage was required in 59 patients (6.8%). The other complications were 19 (2.2%) cases of bloody sputum, 3 (0.35%) cases of intravascular air, 1 (0.12%) case of pneumonia and 1 (0.12%) case of cerebral infarction. There were no lipiodol marking-induced deaths or sequelae.CONCLUSIONSPreoperative CT-guided lipiodol marking followed by VATS resection was shown to be a safe and reliable procedure with a high success rate and acceptably low severe complication rate.

  • The 6-min walk test in the functional evaluation of patients with lung
           cancer qualified for lobectomy
    • Authors: Wesolowski S; Orlowski T, Kram M.
      Pages: 559 - 564
      Abstract: OBJECTIVESThe American College of Chest Physicians guidelines recommend low-technology exercise tests in the functional evaluation of patients with lung cancer considered for resectional surgery. However, the 6-min walk test (6MWT) is not included, because the data on its clinical value are inconsistent. Our goal was to evaluate the 6MWT in assessing the risk of cardiopulmonary complications in candidates for lung resection.METHODSWe performed a retrospective assessment of clinical data and pulmonary function test results in 947 patients, mean age 65.3 (standard deviation 9.5) years, who underwent a single lobectomy for lung cancer. In 555 patients with predicted postoperative values ≤60%, the 6MWT was performed. The 6-min walking distance (6MWD) and the distance-saturation product (DSP), which is the product of the 6MWD in metres, and the lowest oxygen saturation registered during the test were assessed.RESULTSA total of 363 patients with predicted postoperative values <60% and a 6MWT distance (6MWD) ≥400 m or DSP ≥ 350 m% had a lower rate of cardiopulmonary complications than patients with shorter 6MWD or lower DSP values [odds ratio (OR) 0.53, 95% confidence interval (CI) 0.35–0.81] and 0.47 (95% CI 0.30–0.73), respectively. This result was also true for patients with predicted postoperative values <40%, ORs 0.33 (95% CI 0.14–0.79) and 0.25 (95% CI 0.10–0.61), respectively.CONCLUSIONSThe 6MWT is useful in the assessment of operative risk in patients undergoing a single lobectomy for lung cancer. It helps to stratify the operative risk, which is lower in patients with 6MWD ≥400 m or DSP ≥350 m% than in patients with a shorter 6MWD or lower DSP values.

  • Video-assisted thoracoscopic thymectomy is feasible for large thymomas: a
           propensity-matched comparison
    • Authors: Weng W; Li X, Meng S, et al.
      Pages: 565 - 572
      Abstract: OBJECTIVESVideo-assisted thoracoscopic thymectomy is becoming the preferable approach for early-stage thymoma. However, large thymomas are still recognized as a relative contraindication due to the possible risk of incomplete resection or capsular disruption. Thus, the aim of this study is to evaluate the feasibility of video-assisted thoracoscopic thymectomy for large thymomas.METHODSPatients diagnosed with Masaoka stage I–IV thymoma between April 2001 and December 2018 were retrospectively reviewed. All patients were divided into 2 groups: thymoma <5.0 cm (group A) and thymoma ≥5.0 cm (group B). Propensity score matching analysis was performed to compare postoperative results. Recurrence-free survival and overall survival were compared for oncological evaluation.RESULTSA total of 346 patients were included in this study. In the propensity score matching analysis, 126 patients were included both in group A and group B. There was no significant difference between these 2 groups in terms of the R0 resection rate (95.2% vs 94.4%, P = 1.000), conversion rate (1.6% vs 3.2%, P = 0.684), operation time (119.4 ± 48.4 vs 139.1 ± 46.6 min, P = 0.955), blood loss (93.2 ± 231.7 vs 100.5 ± 149.3 ml, P = 0.649), duration of chest drainage (2.7 ± 1.6 vs 2.8 ± 2.0 days, P = 0.184), length of hospitalization (5.0 ± 3.9 vs 5.2 ± 2.9 days, P = 0.628) or postoperative complications (5.9% vs 8.5%, P = 0.068). There was no significant difference between these 2 groups in terms of the overall survival (P = 0.271) and recurrence-free survival (P = 0.288).CONCLUSIONSVideo-assisted thoracoscopic thymectomy is a safe and effective approach for large thymomas (≥5 cm) with comparable surgical and oncological results.

  • Thrombotic risk following video-assisted thoracoscopic surgery versus open
           thoracotomy: a systematic review and meta-analysis
    • Authors: Spiezia L; Liew A, Campello E, et al.
      Pages: 573 - 581
      Abstract: OBJECTIVESThere is no consensus on the risk of thrombotic events following video-assisted thoracoscopic surgery (VATS) versus open thoracotomy (OT), despite multiple studies. In fact, the estimates for the overall thrombotic risk for VATS versus OT are inconclusive. In this systematic review and meta-analysis, we endeavoured to ascertain the best estimate of thrombotic risk in VATS versus OT.METHODSRelevant studies were searched through PubMed and Cochrane Library database. Outcomes of interests were myocardial infarction (MI), pulmonary embolism (PE) and deep vein thrombosis (DVT). Data were pooled using random-effects model. The results were presented as odds ratio (OR) with the corresponding 95% confidence interval (CI).RESULTSNineteen studies were meta-analysed: 17 observational studies and 2 randomized controlled trials. Using propensity-matched data, in comparison with OT, VATS was associated with a statistically significant, postoperative reduction in MI (OR 0.60, 95% CI 0.39–0.91; P = 0.017), DVT/PE (OR 0.52, 95% CI 0.44–0.61; P < 0.001), PE (OR 0.59, 95% CI 0.43–0.82; P = 0.001) and DVT (OR 0.47, 95% CI 0.35–0.64; P < 0.001). Unadjusted data showed no statistical differences for all outcomes. The risk of DVT/PE (OR 0.55, 95% CI 0.42–0.72; P < 0.001), but not the other outcomes, remained significantly lower following the exclusion of the sole large study. There is no significant statistical heterogeneity between the included studies.CONCLUSIONSOverall, the postoperative thrombotic risk following VATS is significantly lower than OT. Further prospective randomized controlled trials with large sample sizes are warranted to corroborate our findings.

  • Is surgical resection of primary tumour superior to exploratory
           thoracotomy without resection in treating lung cancer patients with
           unexpected pleural metastasis detected during operation'
    • Authors: Deng H; Zheng X, Zhu D, et al.
      Pages: 582 - 587
      Abstract: A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was ‘In lung cancer patients with unexpected pleural metastasis detected during operation, is surgical resection of primary tumour superior to exploratory thoracotomy without resection in improving long-term survival'’. Altogether, 1443 papers were found using the reported search, of which 1 meta-analysis and 10 retrospective observational cohort studies represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers were tabulated. One meta-analysis and 9 cohort studies found that surgical resection of the primary tumour, on the discovery of pleural metastases, yielded a better overall survival than exploratory thoracotomy alone, while 1 cohort study showed no difference. Six studies found that main tumour resection was an independent favourable prognostic factor for overall survival in lung cancer patients with unexpected pleural metastasis detected during operation, while 3 cohort studies also showed improved progression-free survival over exploratory thoracotomy. Therefore, we conclude that surgical resection of the primary tumour is superior to exploratory thoracotomy in treating lung cancer patients with unexpected pleural metastasis detected during operation.

  • 18F-fluorodeoxyglucose positron emission tomography in malignant pleural
           mesothelioma: diagnostic and prognostic performance and its correlation to
           pathological results
    • Authors: Lococo F; Rena O, Torricelli F, et al.
      Pages: 593 - 596
      Abstract: Although 18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) scan has been generally validated in the staging of malignant pleural mesothelioma (MPM), its diagnostic and prognostic performances are not clearly established. Aiming to identify possible factors causing 18F-fluorodeoxyglucose PET/CT false-negative results and influencing prognosis in MPM patients, we analysed clinical, radiometabolic and pathological features in 141 MPM patients who underwent diagnostic 18F-fluorodeoxyglucose PET/CT scan (January 2009–July 2018) at 2 high-volume institutions. The Fisher’s exact test and the Cox model were used in statistical analysis. Overall detection rate was 88.3% with 16 patients (11.6%) presenting with a standardized uptake value (SUV) max <2.5 (PET-negative). PET-negative cases were more frequently detected in older patients (P = 0.027) and early-stage tumours (33.3% false-negative in stage I and 40.0% false-negative in T1-tumours, with P = 0.014 both). Mean SUVmax value was higher in sarcomatoid (11.8 ± 4.6) and biphasic MPM (9.3 ± 7.0), rather than in epithelioid MPM (6.9 ± 3.8, P < 0.001). Concerning overall survival, SUVmax (both as continuous and as categorical variable) was found to be a prognostic factor, in addition to stage (P = 0.032) and histology (P = 0.014) as confirmed by multivariable analysis (hazard ratio 2.65, confidence interval 1.23–5.70; P < 0.001). In the light of such results, we highlight that a low fluorodeoxyglucose uptake might be observed in more than 10% MPMs, especially in early-stage tumours affecting elderly patients. Furthermore, high SUVmax values significantly correlated with a worse prognosis.

  • Testing the clinical validity of the Bemelman Rib Fracture Management
           Guideline
    • Authors: Dorman J; Clarke P, Simpson R, et al.
      Pages: 597 - 599
      Abstract: Whilst surgical stabilization of rib fractures (SSRF) results in better outcomes, selection algorithms are lacking. We aimed to validate the Rib Fracture Management Guideline proposed by Bemelman. From a cohort of 792 patients with multiple rib fractures, 2 sequential cohorts were selected: 48 patients who underwent SSRF and 48 patients who managed conservatively. Admission computed tomography scans and records were reviewed by an investigator blinded to the SSRF outcome. Adherence to the Bemelman guideline, revised to take account of consensus rib fracture definitions, was tested. Fifty-seven patients had multiple rib fractures only, and 39 patients also had a flail segment. Thirty-nine patients with flail segment underwent SSRF, and 18 patients were managed conservatively. Of the patients that the guideline predicted should have received surgery, 87% did. Of those that it predicted should not receive SSRF, 98% did not. The guideline displayed a sensitivity (95% confidence interval) and specificity for predicting the fixation of 0.98 (0.89–0.9995) and 0.83 (0.70–0.93), respectively. The positive and negative predictive values for surgical fixation were 0.87 (0.76–0.92) and 0.98 (0.85–0.99), respectively. The Bemelman guideline was thus a good predictor of SSRF in retrospective cohort but should be used in conjunction with clinical judgement. Further validation is indicated in a prospective study.

  • Patient eligibility for application of a two-filter cerebral embolic
           protection device during transcatheter aortic valve implantation: does one
           size fit all'
    • Authors: Voss S; Schechtl J, Nöbauer C, et al.
      Pages: 605 - 612
      Abstract: OBJECTIVESThis study sought to determine the percentage of patients potentially eligible for implantation of the Sentinel™ Cerebral Protection System (Sentinel-CPS) during transcatheter aortic valve implantation (TAVI) and to identify the reasons for treatment exclusion.METHODSWe retrospectively performed an analysis of pre-TAVI multislice computed tomography (MSCT) aortograms and data review of all patients undergoing a TAVI procedure in 2017 (n = 317). MSCT evaluation included the assessment of aortic arch anatomy and the vascular dimensions of the brachiocephalic and left common carotid artery. Data analysis focused on comorbid conditions, precluding 6-Fr sheath radial access and filter deployment due to history of previous artery interventions.RESULTSMSCT and data analysis showed Sentinel-CPS compatibility in 61.5% of patients (n = 195). Sentinel-CPS would have been contraindicated in 38.5% (n = 122) due to one or more of the following: (i) measured diameters of the filter-landing zones <9 or >15 mm in the brachiocephalic artery and <6.5 or >10 mm in the left common carotid artery (n = 116; 88 with carotid dimensions too small); (ii) significant subclavian artery stenosis (n = 4) or an aberrant subclavian artery (n = 3) precluding Sentinel-CPS implantation and (iii) clinical characteristics including hypersensitivity to nickel–titanium (n = 1), radial artery occlusion (n = 1) or previous left common carotid artery interventions (n = 5).CONCLUSIONSMSCT and clinical data supported Sentinel-CPS compatibility in 61.5% of patients. The most common reason for treatment exclusion was inappropriate diameter within the target landing zone of the left carotid artery. Future device development should address this limitation.

  • Preoperative neurological deficit in acute type A aortic dissection
    • Authors: Kreibich M; Desai N, Bavaria J, et al.
      Pages: 613 - 619
      Abstract: OBJECTIVESOur goal was to evaluate postoperative outcomes in patients with type A aortic dissection with preoperative neurological deficits independent of shock.METHODSBetween 2002 and 2017, 150 of 1600 patients, operated on for aortic dissection type A in 3 centres, presented with preoperative new onset neurological deficits. Postoperative outcomes were classified using a modified Rankin Scale (mRS) as ‘no to moderate disability’ (mRS 0–3) or as ‘poor clinical outcome’ (mRS 4–6). Clinical and radiographic data were analysed.RESULTSNinety-three patients (62%) had no to moderate disability and 57 (38%) had a poor clinical outcome. The in-hospital mortality rate was 18% (28 patients). Patients with poor clinical outcomes were significantly older (P = 0.01) and had a significantly higher incidence of hypertension (P = 0.04), history of stroke (P = 0.03) and common carotid artery occlusion (left common carotid artery: P = 0.01; right common carotid artery: P < 0.01). One-third of all patients developed haemodynamic instability (P = 0.27). Cardiopulmonary bypass (P < 0.01) and cross-clamp (P = 0.03) times were significantly longer in patients with poor clinical outcomes. Age (odds ratio 1.041; P = 0.02) and history of stroke (odds ratio 2.651; P = 0.03) were predictive of poor clinical outcome; coma was not. Haemorrhagic transformation occurred in 7 patients without any independent predictors.CONCLUSIONSMost patients with preoperative neurological deficit have no to moderate disability postoperatively but commonly develop preoperative haemodynamic instability. This study suggests that an immediate surgical approach may be reasonable in patients with preoperative neurological deficit or coma.

  • Extra-anatomical bypass to treat aortic endograft infection after thoracic
           endovascular aortic repair
    • Authors: Tang Y; Han L, Fan X, et al.
      Pages: 620 - 622
      Abstract: This study aimed to report the case of 7 consecutive patients who underwent surgical treatment for aortic endograft infection after thoracic endovascular aortic repair (TEVAR). The management included the reconstruction of aorta using extra-anatomic prosthetic graft bypass (between the ascending aorta and the abdominal aorta), removal of the infected endograft with debridement of the infected tissue and sac drainage, followed by prolonged antibiotic therapy. This brief communication highlights that the reconstruction of aorta using extra-anatomic prosthetic graft bypass during surgical treatment for aortic endograft infection after TEVAR was reliable and effective.

  • Effects of levosimendan on ventriculo-arterial coupling and cardiac
           efficiency in paediatric patients with single-ventricle physiology after
           surgical palliation: retrospective study
    • Authors: Iacobelli R; Ricci Z, Marinari E, et al.
      Pages: 623 - 629
      Abstract: OBJECTIVESThe use of levosimendan for paediatric patients with low cardiac output after congenital heart surgery has been recently described. We sought to evaluate ventriculo-arterial coupling (VAC) and other ventricular energetic parameters before and after 72 h from levosimendan start in infants with single-ventricle physiology and cardiac failure after palliation with Norwood or hybrid procedures.METHODSIn this single-centre retrospective study, 9 consecutive patients affected by hypoplastic left heart syndrome-like anatomy were retrospectively analysed. Systolic elastance, diastolic elastance, arterial elastance, VAC and cardiac mechanical efficiency were calculated by measuring, through 2-dimensional echocardiography, end-systolic volume and end-diastolic volume and by recording mean arterial pressure and central venous pressure.RESULTSThe median (range) weight and age were 2.8 (2.3–6) kg and 16.5 (6–116) days, respectively. After 72 h from levosimendan start, end-systolic volume significantly decreased (−1 ml, −3.2 to −0.1, P = 0.007), whereas mean arterial pressure and end-diastolic volume remained stable. Heart rate showed a significant decrease (−28 beats/min, −41 to 22, P = 0.008). Systolic elastance (2.9 mmHg/ml, 0.4–5.4, P = 0.008), arterial elastance (−5.9, −24 to −0.5, P = 0.038), VAC (−0.86, −1.5 to −0.16, P = 0.009) and cardiac mechanical efficiency (0.18, 0.03–0.22, P = 0.008) differences also showed significant modifications.CONCLUSIONSIn a small case series of patients with single-ventricle physiology, levosimendan showed to improve contractility and optimize VAC, with a reduction of heart rate. Monitoring of VAC and ventricular energetics can be an interesting aspect to improve the management of heart failure in infants with univentricular anatomy.

  • The effects of steroidal and non-steroidal anti-inflammatory drugs on
           tracheal wound healing in an experimental rat model
    • Authors: Duman E; Ceylan K, Akpınar D, et al.
      Pages: 646 - 651
      Abstract: OBJECTIVESThe effect of non-steroidal anti-inflammatory drugs (NSAID), mostly used for postoperative analgesic purposes for wound healing, is still a matter of debate. Our goal was to evaluate the effects of the most widely used NSAID and corticosteroids after surgical operations on tracheal wound healing in an experimental rat model.METHODSThirty-nine male Wistar albino rats were included in this study. Tracheotomy was performed in 32 rats; then they were divided into 3 groups. After the first day, the animals in group 1 were treated with an NSAID (diclofenac 10 mg/kg/day) (NSAID, n = 12) for 7 days; the animals in group 2 were treated with a corticosteroid (dexamethasone, 2 × 0.1 mg/kg/day) (steroid, n = 10) for 7 days; the animals in group 3 (control, n = 10) were not given any medications. For a fourth group (histological control, n = 7), in order to evaluate normal morphological and histological characteristics, neither surgery nor medication was used. Five rats were eliminated from the study (2 rats in the NSAID group died and 3 rats in the steroid group developed local wound infections). The drop-out rate was 12.8%. Histological characteristics, inflammation, fibrosis, necrosis, neochondrogenesis, neovascularization and epithelization were evaluated in 34 rats. Non-parametric tests were used for statistical analysis.RESULTSInflammation, vascularization and number of fibroblasts and chondrocytes were significantly higher in the control group than in the histological control group. There was some reduction in all parameters except vascularization in the NSAID group (P > 0.05). When the steroid group was compared to the NSAID group, inflammation (P < 0.05), vascularization and number of chondrocytes (P > 0.05) were more suppressed in the steroid group. The number of fibroblasts increased in the steroid group (P > 0.05).CONCLUSIONSSteroids and NSAID may have negative effects on tracheal wound healing, probably by suppressing inflammation and fibroblast proliferation. NSAID was mostly used postoperatively for analgesic purposes and should be avoided.

           after multistep surgeries in thoraco-abdominal aortic aneurysm repair
    • Authors: Sakatsume K; Kawatsu S, Adachi O, et al.
      Pages: 656 - 658
      Abstract: Herein, we report a case of thoraco-abdominal aortic repair in a 55-year-old man with a multiple treatment history for aortic aneurysm and aortic dissection. A computed tomography scan revealed that the Adamkiewicz artery was connected to an occluded intercostal artery, suggesting that the left inferior epigastric artery was the key artery supplying the Adamkiewicz artery; the key artery was identified through direct monitoring of cerebrospinal fluid temperature and selective hypothermic perfusion. No spinal cord injury was detected during the postoperative period.

  • Aortic calcifications on routine preoperative chest X-ray and
           perioperative stroke during cardiac surgery: a nested matched
           case–control study
    • Authors: Knol W; Bogers A, Braun L, et al.
      Pages: 507 - 514
      Abstract: OBJECTIVESPerioperative stroke in cardiac surgery is most often embolic in origin. Preoperative chest X-ray (CXR) is routinely used amongst others to screen for relevant aortic calcification, a potential source of embolic stroke. We performed a nested matched case–control study to examine the relationship between aortic calcifications on CXR and the occurrence of embolic stroke.METHODSAmong all consecutive patients undergoing cardiac surgery in our hospital between January 2014 and July 2017, we selected all patients with perioperative embolic stroke (cases). Controls, all patients without perioperative stroke, were matched on age, sex and type of surgery. All preoperative CXRs were scored for aortic calcifications (none, mild, severe) in the ascending aorta, arch, aortic knob and descending aorta.RESULTSOut of the 3038 eligible patients, 27 cases were detected and 78 controls were selected. In the stroke group, mild-to-severe calcifications were found least often in the ascending aorta [9% of patients, 95% confidence interval (CI) 1–29%] and most frequently in the aortic knob (63% of patients, 95% CI 44–78%). The distribution of aortic calcification was comparable in cases versus controls.CONCLUSIONSCalcification burden was comparable between the cases and their matched controls. In our study population, CXR findings on aortic calcification were not related to the risk of embolic stroke. In these patients, the correlation between findings on the preoperative CXR and the risk of stroke might, therefore, be too weak to use the CXR directly for the assessment of the safety of manipulating the ascending aorta during surgery.

  • Preoperative skeletal muscle density is associated with postoperative
           mortality in patients with cardiovascular disease
    • Authors: Yamashita M; Kamiya K, Matsunaga A, et al.
      Pages: 515 - 522
      Abstract: OBJECTIVESAlthough skeletal muscle density (SMD) is useful for predicting mortality, the cut-off in an acute clinical setting is unclear, especially in patients with cardiovascular disease (CVD). This study was performed to determine the preoperative SMD cut-off using the psoas muscle and to investigate the effect on postoperative outcomes, including sarcopaenia, in CVD patients.METHODSPreoperative psoas SMD was measured by abdominal computed tomography in CVD patients. Postoperative sarcopaenia was defined according to the criteria of the Asia Working Group for Sarcopaenia. The Youden index was used to test the predictive accuracy of survival models. The prognostic capability was evaluated using multivariable survival and receiver operating characteristic curve analyses.RESULTSContinuous data were available for 1068 patients (mean age 65.5 years; 63.6% male). A total of 105 (9.8%) deaths occurred during the 1.99-year median follow-up period (interquartile range 0.71–4.15). The psoas SMD cut-off estimated by the Youden index was 45 Hounsfield units with high sensitivity and moderate specificity for all-cause mortality and was consistent in various stratified analyses. After adjusting for the existing prognostic model, EuroSCORE II, preoperative and postoperative physical status, psoas SMD cut-off was predicted for mortality (hazard ratio 2.42, 95% confidence interval 1.32–4.45). The psoas SMD cut-off was also significantly associated with postoperative sarcopaenia and provided additional prognostic information to EuroSCORE II on receiver operating characteristic curve analysis (area under the curve 0.627 vs 0.678, P = 0.011).CONCLUSIONSReduced psoas SMD was associated with postoperative mortality and added information prognostic for mortality to the existing prognostic model in CVD patients.

  • Surgery in drug use-associated infective endocarditis: long-term survival
           is negatively affected by recurrence
    • Authors: Rohn V; Laca B, Horn M, et al.
      Pages: 528 - 534
      Abstract: OBJECTIVESThe prevalence of infectious endocarditis (IE) in intravenous drug users (IDUs) is increasing, and the number of patients who need surgery is also rising. Relatively little is known about the short-term and long-term outcomes of these operations.METHODSThis study is a retrospective analysis of our institutional results, focussing on risk factors for perioperative death, major adverse events and long-term survival. A total of 50 of the 66 (75.75%) patients had postoperative follow-up, and the mean follow-up time was 53.9 ± 9.66 months. Patients were divided into 2 groups depending on whether they were having their first operation or were being reoperated for recurrent IE.RESULTSFrom March 2006 to December 2015, a total of 158 patients underwent surgery for IE; 72 (45.6%) of them were identified as active IDUs. The operative mortality in IDUs was 8.33% (6 patients), with no significant difference between the 2 groups (P = 0.6569). Survival rates at 1 year, at 3 years and at the end of follow-up were 92%, 72% and 64%, respectively. There was significantly worse survival of patients with recurrent IE (log-rank test, P = 0.03).CONCLUSIONSAlthough the short-term results of operation for IE in IDUs are good, long-term outcomes are not satisfactory. The survival of patients with recurrence of IE caused by return to intravenous drug use is significantly worse.

  • Screening and topical decolonization of preoperative nasal Staphylococcus
           aureus carriers to reduce the incidence of postoperative infections after
           lung cancer surgery: a propensity matched study
    • Authors: Fourdrain A; Bouabdallah I, Gust L, et al.
      Pages: 552 - 558
      Abstract: OBJECTIVESHealth care-associated infections (HAIs) are serious issues following lung cancer surgery, leading to an increased risk of morbidity and hospital cost burden. The aim of this study was to evaluate the impact on postoperative outcomes of a preoperative screening and decolonization strategy of nasal carriers for Staphylococcus aureus prior to lung cancer surgery.METHODSWe performed a retrospective study comparing 2 cohorts of patients undergoing major lung resection: a control group of patients from the placebo arm of the randomized Clinical Study to Evaluate the Efficacy of Chlorhexidine Mouthwashes operated on between July 2012 and April 2015 without any nasopharyngeal screening (N = 224); an experimental group, with preoperative screening for S. aureus of nasal carriers and selective 5-day decolonization in positive carriers using mupirocin ointment between January 2017 and December 2017 (N = 310). The 2 groups were matched according to a propensity score analysis with 1:1 matching. The primary outcome was the rate of postoperative HAIs, and the secondary outcome was the need for postoperative mechanical ventilation after surgery.RESULTSAfter matching, 2 similar groups of 108 patients each were obtained. In the experimental group, 26 patients had positive results for nasal carriage, and a significant decrease was observed in the rate of overall postoperative HAIs [control n = 19, 17.6%; experimental group n = 9, 8.3%; P = 0.043; relative risk 0.47 (0.22–1)] and in the rate of postoperative mechanical ventilation [control n = 12, 11.1%; experimental group n = 4, 3.7%; P = 0.038; relative risk 0.33 (0.11–1)]. After logistic regression and multivariable analysis, screening of S. aureus nasal carriers reduced the rate of HAIs [odds ratio (OR) 0.29, 95% confidence interval (CI) 0.11–0.76; P = 0.01] and reduced the risk of the need for postoperative mechanical ventilation (OR 0.19, 95% CI 0.05–0.74; P = 0.02). There was no significant statistical difference between the 2 groups regarding the rate of postoperative S. aureus-associated infection (control group n = 6, 5.6%; experimental group n = 2, 1.9%; P = 0.28).CONCLUSIONSIdentification of nasal carriers of S. aureus and selective decontamination using mupirocin appeared to have a beneficial effect on postoperative infectious events after lung resection surgery.

  • In patients undergoing video-assisted thoracic surgery for lung resection,
           does three-dimensional endoscopic vision provide superior clinical
           outcomes'
    • Authors: Chandarana K; Caruana E.
      Pages: 588 - 592
      Abstract: A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether the use of 3-dimensional endoscopic vision provides superior clinical outcomes to patients undergoing video-assisted thoracic surgery for lung resection. Altogether 231 unique papers were found using the reported search, of which 6 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Four of the 6 papers demonstrated a statistically significant reduction in operative time, although this difference may not be of sufficient magnitude to be relevant clinically. There was no difference in any other outcomes assessed. We therefore conclude that, in patients undergoing video-assisted thoracic surgery for lung resection, 3-dimensional endoscopic vision has no demonstrable impact on perioperative or oncological outcomes, or cost, although it may reduce operative time.

  • Decreased biventricular function following thoracic endovascular aortic
           repair
    • Authors: Kreibich M; Morlock J, Beyersdorf F, et al.
      Pages: 600 - 604
      Abstract: OBJECTIVESPreclinical studies have suggested acute stiffening of the aorta following experimental thoracic endovascular aortic repair (TEVAR), resulting in acute elevated pulse pressure, hypertension and possibly heart failure. The aim of this study was to evaluate cardiac remodelling following TEVAR.METHODSFrom 2005 to 2018, 519 TEVAR procedures were performed at a single centre. Transthoracic echocardiography was performed pre- and post-TEVAR in 31 patients without previous replacement of the thoracic aorta. Patient characteristics, drug information, radiographic and follow-up data were evaluated. Aortic details were measured in multiplanar reconstruction.RESULTSTransthoracic echocardiography was performed 2 ± 2 years after TEVAR. At this time, patients received significantly more antihypertensive drugs compared to the pre-TEVAR intake (beta-blocker therapy: P = 0.037; calcium channel blocker: P = 0.022). Compared to pre-TEVAR, there was a significant reduction in the left ventricular ejection fraction (P = 0.008) and tricuspid annular plane systolic excursion (P = 0.013) post-TEVAR. A significant increase in the left ventricular mass was not detected in this study (P = 0.95). The mean distance of 163 ± 66 mm of the descending aorta was covered.CONCLUSIONSThis study suggests negative cardiac remodelling with a decrease in the left and right ventricular function following TEVAR despite an increase in oral antihypertensive medication. The impact of stiffer endovascular grafts compared with the native aortic wall should be considered by endovascular specialists and manufacturers.

  • Choice of shunt type for the Norwood I procedure: does it make a
           difference'
    • Authors: Vitanova K; Georgiev S, Lange R, et al.
      Pages: 630 - 635
      Abstract: OBJECTIVESThis study aimed to compare pulmonary artery (PA) growth between patients who received a right ventricle-to-PA (RV–PA) shunt and those who received a modified Blalock–Taussig shunt (mBTS).METHODSAll consecutive patients with hypoplastic left heart syndrome who underwent the Norwood I procedure between 2001 and 2017 were included in the study. Pre-stage 2 angiograms were analysed to measure the size of the PA. The Nakata index was calculated to estimate PA growth. The ratio of the right PA to left PA cross-sectional area (RPA/LPA) was used to calculate the difference in growth between the 2 branches. Study end points were shunt failure, shunt-related mortality and growth of the PAs.RESULTSA total of 223 patients with hypoplastic left heart syndrome (RV–PA group = 137, mBTS group = 86) underwent the Norwood I procedure, and 186 patients (RV–PA n = 116, mBTS n = 70) achieved the stage 2 procedure. PA growth was better in patients with mBTS (Nakata index: RV–PA = 282, mBTS = 315 mm2/m2, P = 0.021). LPA growth was worse compared to RPA growth in both groups (RPA/LPA: RV–PA = 1.21, mBTS = 1.29, P = 1.0). Patients with RV–PA shunts experienced more frequent shunt stenosis compared to patients with mBTS (26 vs 2, P < 0.010). Freedom from shunt failure was 83.3 ± 3.2% and 94 ± 2% at 6 months in the RV–PA and mBTS groups, respectively (P = 0.003).CONCLUSIONSPA growth is significantly better in patients who received an mBTS. Moreover, patients with an RV–PA shunt more frequently experienced shunt failure due to shunt stenosis. However, survival after the NW procedure is not shunt dependent and growth of the LPA is less pronounced than RPA, regardless of the shunt type.

  • Off-pump tricuspid valve repair by automated sutured tricuspid annular
           plication via transatrial cannulation: preclinical ex vivo and in vivo
           results
    • Authors: Werner P; Russo M, Sauer J, et al.
      Pages: 636 - 645
      Abstract: OBJECTIVESSurgical repair is considered the gold standard treatment for severe symptomatic tricuspid valve (TV) regurgitation. However, patients undergoing isolated surgical tricuspid repair face a high perioperative mortality while long-term data on interventional treatment options are currently missing. We investigated a novel, minimally invasive approach for transatrial off-pump beating-heart tricuspid annular plication based on the surgical Hetzer repair.METHODSTV annular plication for the creation of a double-orifice valve using novel devices for automated annular suturing was performed in 10 human heart specimens in an ex vivo perfusion model under endoscopic guidance. Additionally, the technique was tested in an in vivo porcine model using the transatrial access under echocardiographic and fluoroscopic guidance.RESULTSEndoscopically guided conduction of the procedure was successful in all 10 human heart specimens in the ex vivo perfusion model with 1 observed suture pull-through of 60 sutures placed (1.7%). TV measurements yielded significant reductions of the TV septal–lateral diameter (50.9 ± 7.3 vs 42.6 ± 7.9 mm; P = 0.015) and the TV area (1208 ± 399 vs 193 ± 122 mm2; P < 0.0001). TV plication without direct vision using device-embedded intracardiac echocardiography, epicardial echocardiography and fluoroscopy was feasible in both acute animals with no observed device-related adverse events.CONCLUSIONSSuccessful plication was completed in 10 ex vivo human hearts, additionally proof-of-concept was conducted in 2 animals. We herein present encouraging early preclinical results of a novel minimally invasive technique for TV repair, which warrants further investigation.
