  • Right ventricular remodelling after tetralogy of Fallot repair: new
           insights from longitudinal follow-up data
    • Authors: Mertens LL.
      Abstract: Surgical relief of right ventricular (RV) outflow tract obstruction in patients with tetralogy of Fallot (TOF) often results in significant pulmonary regurgitation, especially in patients requiring transannular patch repair. The resulting RV volume loading associated with the regurgitation is considered the main factor contributing to RV eccentric remodelling resulting in progressive RV dilation early after surgery. Although the remodelling can partially be considered as compensatory, pathological remodelling with development of RV damage and dysfunction can occur over time.1 Other factors contribute to this adverse RV remodelling. Some patients may have variable degrees of RV fibrosis prior to surgical repair which influences RV diastolic function after repair. The surgical outflow patch typically extends into the RV anterior wall causing regional RV scarring and dysfunction.2 Additionally, surgical repair almost inevitably causes right bundle branch resulting in RV electromechanical dyssynchrony which can be an additional factor contributing to progressive RV dilatation and dysfunction.3 Through adverse ventricular interactions the RV can influence left ventricular (LV) function and a close association between RV and LV ejection fraction (EF) has been demonstrated in postoperative TOF patients. Development of LV dysfunction is a strong prognostic factor for adverse outcomes in this population.4

  • Comprehensive multi-modality imaging approach in arrhythmogenic
           cardiomyopathy—an expert consensus document of the European Association
           of Cardiovascular Imaging
    • Authors: Haugaa KH; Basso C, Badano LP, et al.
      Abstract: Arrhythmogenic cardiomyopathy (AC) is a progressive disease with high risk of life-threatening ventricular arrhythmias. A genetic mutation is found in up to 50–60% of probands, mostly affecting desmosomal genes. Diagnosis of AC is made by a combination of data from different modalities including imaging, electrocardiogram, Holter monitoring, family history, genetic testing, and tissue properties. Being a progressive cardiomyopathy, repeated cardiac imaging is needed in AC patients. Repeated imaging is important also for risk assessment of ventricular arrhythmias. This expert consensus document gives clinical recommendations for how to use multi-modality imaging in the different aspects of AC disease, including diagnosis, family screening, follow-up, risk assessment, and differential diagnosis.

  • Tricuspid regurgitation repair with a MitraClip device: the pivotal role
           of 3D transoesophageal echocardiography
    • Authors: Avenatti E; Barker CM, Little SH.
      Abstract: A 77-year-old male presented with congestive heart failure (NYHA class IV) despite maximal medical therapy. Right sided features were predominant; transoesophageal echocardiography (TEE) revealed severe tricuspid regurgitation (TR) (Panel A: 1: 3D TEE; 2. 2D TEE, 3. Colour Doppler; see Supplementary data online, video 1Supplementary data online, video 1) without leaflet coaptation (white asterisk). Due to prohibitive surgical risk, a catheter based intervention with a MitraClip (Abbott, USA) device was considered.

  • Athlete’s heart vs. apical hypertrophic cardiomyopathy: look again!
    • Authors: Samad F; Harland DR, Girzadas M, et al.
      Abstract: An asymptomatic, athletic 53-year-old man was evaluated for an abnormal life insurance electrocardiogram (ECG) that showed deep T-wave inversions (15 mm) across the anterior leads (Panel A). He was a passionate cyclist and cycled more than 100 miles per week. The abnormal ECG prompted a transthoracic echocardiogram (TTE) for evaluation of apical hypertrophic cardiomyopathy (ApHCM). TTE demonstrated mildly increased left ventricular wall thickness, ejection fraction of 67%, and average global longitudinal strain (GLS) of −23.8% (Panels B and C) with normal diastology. In light of an ambiguous diagnosis of ApHCM, he was referred to our hypertrophic cardiomyopathy centre. Repeat TTE with focused apical imaging revealed apical hypertrophy (22 mm) without an apical aneurysm/pouch (Panel D). Global (−16%) and regional (apical [−9%]) strains were reduced consistent with ApHCM (Panel E). Cardiac magnetic resonance imaging confirmed the diagnosis of ApHCM (apical thickness of 20 mm) (Panel F) with 10% mid-myocardial delayed enhancement (Panel G) and without an apical pouch. The patient was started on a calcium channel blocker and was recommended a 6-month follow-up.

  • Rare association of endomyocardial fibrosis and Chagas heart disease
    • Authors: Hotta V; Ianni B, Assunção A, Jr, et al.
      Abstract: Chagas heart disease (CD) and endomyocardial fibrosis (EMF) are distinct and uncommon cardiomyopathies that can lead to a very poor prognosis. Both diseases are mostly found in African and South- and Central American countries. The patient presented in this case was from an area in Brazil endemic for Chagas disease. CD results from infection by the protozoan Trypanossoma cruzi and is associated with typical electrocardiographic and echocardiographic findings, including posteroinferior wall motion abnormalities in the left ventricle, as well as apical aneurysm. On the other hand, the underlying cause and mechanisms of EMF remain unclear. Obliteration of one or both ventricular apices might be seen. The left ventricular (LV) ejection fraction is usually preserved.

  • Severe mitral regurgitation: do not clip the valve—clip the leaflet
    • Authors: Schach C; Birner C, Buchner S.
      Abstract: An 81-year-old male patient with severe mitral regurgitation (MR) was scheduled for percutaneous rather than surgical valve repair due to recurrent episodes of decompensated heart failure (NYHA III-IV) and substantial comorbidities. Transoesophageal echocardiography revealed a prolapse of segment P2 and a significant indentation between segments P1 and P2. Interestingly, dedicated colour Doppler allowed localizing the MR origin within the posterior mitral leaflet at the edge between P2 and P1 rather than between P2 and the anterior leaflet (A and B and Supplementary material onlineSupplementary material online, see Supplementary dataSupplementary data online, Videos S1 and S2, ALC: anterolateral commissure). Regurgitant orifice area determined by 3D vena contracta area was 0.86 cm2 grading the regurgitation as severe.

  • A rare cause of aortic regurgitation and complete atrioventricular block
    • Authors: Cordeiro F; Ferreira C, Salvador F, et al.
      Abstract: A 47-year-old Caucasian male presented with exertional dyspnoea and thoracic pain within the last month. At physical examination, he had bradycardia (heart rate of 45 beats per minute), fever, and a diastolic murmur. Electrocardiogram demonstrated complete atrioventricular block (A). Transthoracic and transoesophageal echocardiogram revealed severe aortic regurgitation due to dilatation and thickening of the aortic root with limited motion of the thickened aortic cusps and dilatation of the left ventricle, with normal ejection fraction (B–E, see Supplementary dataSupplementary data online, Videos S1–S3). Computed tomography angiography also showed a pseudo-aneurysm of the non-coronary Valsalva sinus (F; arrow). Fluorine-18-fluorodeoxyglucose positron emission tomography exhibited tracer uptake in the aortic root, consistent with aortic root inflammation (G). Laboratory tests demonstrated increased inflammatory markers and positive results for myeloperoxidase antibodies of the anti-neutrophil cytoplasmic antibodies; infectious serologies were negative.

  • Recommendations on the echocardiographic assessment of aortic valve
           stenosis: a focused update from the European Association of Cardiovascular
           Imaging and the American Society of Echocardiography
    • Authors: Baumgartner H; (chair), Hung J, (co-chair), Bermejo J, et al.
      Abstract: Echocardiography is the key tool for the diagnosis and evaluation of aortic stenosis. Because clinical decision-making is based on the echocardiographic assessment of its severity, it is essential that standards are adopted to maintain accuracy and consistency across echocardiographic laboratories. Detailed recommendations for the echocardiographic assessment of valve stenosis were published by the European Association of Echocardiography and the American Society of Echocardiography in 2009. In the meantime, numerous new studies on aortic stenosis have been published with particular new insights into the difficult subgroup of low gradient aortic stenosis making an update of recommendations necessary. The document focuses in particular on the optimization of left ventricular outflow tract assessment, low flow, low gradient aortic stenosis with preserved ejection fraction, a new classification of aortic stenosis by gradient, flow and ejection fraction, and a grading algorithm for an integrated and stepwise approach of artic stenosis assessment in clinical practice.

  • Longitudinal changes in adolescents with TOF: implications for care
    • Authors: Bhat M; Mercer-Rosa L, Fogel MA, et al.
      Abstract: BackgroundWe sought to identify predictors of change in right ventricular function and exercise capacity in adolescents following repair for tetralogy of Fallot.Methods and resultsWe performed a longitudinal study with serial cardiac magnetic resonance imaging and/or exercise stress tests. Patients with interim intervention on the pulmonary valve were excluded. Paired t-test was used to detect longitudinal changes and multivariable regression models were built to identify predictors of change. Initial and follow up magnetic resonance and exercise stress test studies were available for 65 and 63 subjects, respectively. Age at initial testing was 11.7 ± 2.7 years. Average follow up time was 4.5 ± 1.8 (magnetic resonance) and 4.0 ± 1.6 (exercise test) years. There was a significant increase in right ventricular end diastolic and systolic volume (119 ± 34 to 128 ± 35 ml/m2, P = 0.006; 49 ± 20 to 56 ± 23 ml/m2, P = 0.001, respectively), and a decrease in right ventricular ejection fraction (60 ± 7 to 56 ± 8%, P = 0.001), with no significant change in pulmonary regurgitant fraction or right ventricular cardiac index. Predictors of right ventricular dilation over time included: time elapsed from surgical repair, severity of pulmonary insufficiency and right ventricular dilation at the initial magnetic resonance imaging. Of those, time elapsed from surgical repair had the most significant effect. There was no change in exercise capacity.DiscussionIn the adolescent with tetralogy of Fallot, longer time from surgery, more pulmonary insufficiency and greater right ventricular dilation at initial magnetic resonance imaging are associated with progressive right ventricular dilation. These results suggest early monitoring with magnetic resonance imaging might identify those at highest risk for progressive disease.

  • Evolution of right ventricular size over time after tetralogy of Fallot
           repair: a longitudinal cardiac magnetic resonance study
    • Authors: Rutz T; Ghandour F, Meierhofer C, et al.
      Abstract: AimsIt is commonly believed that pulmonary regurgitation (PR) after surgical repair of tetralogy of Fallot (TOF) leads to progressive right ventricular (RV) enlargement. However, progressive RV dilatation has never clearly been documented in this patient population. Therefore, we studied the size of the RV over time in patients after surgical TOF repair.Methods and resultsFifty-one consecutive patients after surgical TOF repair underwent at least two cardiovascular magnetic resonance (CMR) exams using a single CMR scanner. Patients with RV outflow tract obstruction, interventions other than the initial repair and CMR exams with use of sedation were excluded. Three subgroups with different repair techniques were studied: transannular patch repair [n = 22, age 17 ± 10 years], subvalvular patch repair [n = 15, age 22 ± 8 years], or non-patch repair/infundibulectomy (n = 14, age 28 ± 11 years). Right ventricular end-diastolic volume index (RVEDVI) and PR fraction did not change during the 37 ± 21 months follow-up between first and last CMR in the whole group (RVEDVI: 118 ± 23 mL/m2 vs. 119 ± 23 mL/m2, P = 0.720; PR fraction: 33% (23–40%) vs. 32% (24–39%), P = 0.268). RVEDVI remained stable in all subgroups (transannular patch: 120 ± 21 mL/m2 vs. 122 ± 22 mL/m2, subvalvular patch: 112 ± 23 mL/m2 vs. 111 ± 23 mL/m2, non-patch: 123 ± 28 mL/m2 vs. 123 ± 23 mL/m2, P = 0.827). RVEDVI at last CMR did not differ between groups (P = 0.301).ConclusionsThis study shows no progression of RV dilatation in patients after surgical repair of TOF with moderately dilated RVs and significant PR during a 3-year follow-up. RV dilatation in our patient group seems to be independent from surgical repair techniques.

  • The absence of a left atrial appendage in a patient with paroxysmal atrial
           fibrillation with a persistent left superior vena cava
    • Authors: Katsumata Y; Kashimura S, Nishiyama T, et al.
      Abstract: A 76-year-old woman with hypertension underwent catheter ablation of paroxysmal atrial fibrillation (AF). She had never experienced any cardiac surgery. The cardiac computed tomography before the ablation revealed no left atrial appendage (LAA), but a large persistent left superior vena cava (PLSVC) in the anteroposterior and left lateral (LL) views (Panels A and B, LSPV; left superior pulmonary vein, LIPV; left inferior pulmonary vein). The PLSVC ran from the innominate vein to the coronary sinus between the left pulmonary veins and the mitral annulus (Panels C, D, E, and F, Ao; aorta, PA; pulmonary artery, RA; right atrium, LA; left atrium). Transesophageal echocardiography and left atrial angiography also demonstrated the lack of the LAA (see the supplementary datasupplementary data online, Videos S1, S2,and S3). The patient underwent a pulmonary vein isolation with a cryoballoon ablation, followed by radiofrequency ablation at the complex fractionated atrial electrogram sites in the PLSVC (Panels E and F).

  • Improved 5-year prediction of all-cause mortality by coronary CT
           angiography applying the CONFIRM score
    • Authors: Deseive S; Shaw LJ, Min JK, et al.
      Abstract: AimsTo investigate the long-term performance of the CONFIRM score for prediction of all-cause mortality in a large patient cohort undergoing coronary computed tomography angiography (CCTA).Methods and resultsPatients with a 5-year follow-up from the international multicentre CONFIRM registry were included. The primary endpoint was all-cause mortality. The predictive value of the CONFIRM score over clinical risk scores (Morise, Framingham, and NCEP ATP III score) was studied in the entire patient population as well as in subgroups. Improvement in risk prediction and patient reclassification were assessed using categorical net reclassification index (NRI) and integrated discrimination improvement (IDI). During a median follow-up period of 5.3 years, 982 (6.5%) of 15 219 patients died. The CONFIRM score outperformed the prognostic value of the studied three clinical risk scores (c-indices: CONFIRM score 0.696, NCEP ATP III score 0.675, Framingham score 0.610, Morise score 0.606; c-index for improvement CONFIRM score vs. NCEP ATP III score 0.650, P < 0.0001). Application of the CONFIRM score allowed reclassification of 34% of patients when compared with the NCEP ATP III score, which was the best clinical risk score. Reclassification was significant as revealed by categorical NRI (0.06 with 95% CI 0.02 and 0.10, P = 0.005) and IDI (0.013 with 95% CI 0.01 and 0.015, P < 0.001). Subgroup analysis revealed a comparable performance in a variety of patient subgroups.ConclusionsThe CONFIRM score permits a significantly improved prediction of mortality over clinical risk scores for >5 years after CCTA. These findings are consistent in a large variety of patient subgroups.

  • Clinical characteristics and determinants of exercise-induced pulmonary
           hypertension in patients with preserved left ventricular ejection fraction
           
    • Authors: Lim A; Kim C, Park S, et al.
      Abstract: AimsRecent studies have shown that exercise-induced pulmonary hypertension (EIPH) is not rare in patients with preserved left ventricular ejection fraction (LVEF). However, the determinants and clinical implication of EIPH in these patients are unclear.Methods and resultsThis study included 1383 patients who were referred for exercise echocardiography to evaluate unexplained exertional dyspnoea or chest discomfort. Pulmonary artery systolic pressure (PASP) was estimated from the maximal velocity of the tricuspid regurgitant jet added to a right atrial pressure of 10 mmHg. EIPH was defined as PASP ≥50 mmHg during exercise. The EIPH group consisted of about one-third of all patients (436 patients, 31.5%). Patients with EIPH were older, more commonly male and had shorter exercise times. In resting echocardiographic findings, the patients with EIPH had worse diastolic function associated with a lower e′ value (7.0 ± 2.0 vs. 7.5 ± 2.3 cm/s, P< 0.001), a longer deceleration time (238.9 ± 54.9 vs. 232.8 ± 46.0 ms, P= 0.043), and a higher E/e′ ratio (10.1 ± 2.9 vs. 9.1 ± 2.7, P< 0.001) compared with those without EIPH. In multivariable analysis, age (P< 0.001), resting E/e′ ratio (P< 0.001), and resting PASP (P< 0.001) were identified as independent determinants of EIPH.ConclusionEIPH was documented in one-third of patients with preserved LVEF. Age, resting E/e′ ratio, and resting PASP were independently associated with EIPH. Therefore, EIPH should be considered as a cause of unexplained exercise intolerance in patients with preserved LVEF.

      Abstract: AimTo assess the impact of left ventricular (LV) filling parameters on outcomes following trans-catheter aortic valve replacement (TAVR).Methods and resultsA total of 526 TAVR patients were compared with 300 patients with severe aortic stenosis (AS) treated conservatively. Clinical variables were collected along with echocardiographic data at baseline, 1 month, and 6 months after study entry. End points included all-cause mortality and the combination of death and heart failure admission. LV filling parameters associated with mortality included reduced A wave velocity (P = 0.005) and shorter deceleration time (DT) (P = 0.0005). DT was superior to all other parameters (P = 0.05) apart from patients with atrial fibrillation in whom E/e′ was better. Short DT (

  • Morphological assessment of chronic total occlusions by combined coronary
           computed tomographic angiography and intravascular ultrasound imaging
    • Authors: Yamamoto M; Maehara A, Poon M, et al.
      Abstract: AimsThe relationship between CTO morphology and vessel remodelling is unclear. We described chronic total occlusion (CTO) morphology using coronary computed tomographic angiography (CCTA) combined with intravascular ultrasound (IVUS).Methods and resultsPre-intervention CCTA and IVUS of 130 CTO lesions (128 patients) were evaluated. Based on CCTA, positive CTO lesion remodelling [PR, maximum CTO segment vessel diameter > proximal reference vessel diameter (RVD)] was seen in 44 (33.8%) lesions. In the other 86 lesions without PR, 74 (56.9%) had a minimum CTO segment vessel diameter >50% of the proximal RVD and were classified as non-PR; 12 (9.2%) lesions had a minimum CTO segment vessel diameter ≤50% of the proximal RVD and were classified as collapse. Comparing the three groups, CTO with PR had the greatest maximum atheroma cross-sectional area (CSA) while the collapse group had the least atheroma CSA (16.0 mm2 [12.0, 19.4] vs. 9.1 mm2 [6.0, 15.9], P < 0.001). The maximum arc of attenuated plaque was greatest in the PR group (51° [0, 167]); and the maximum arc of calcium was greatest in the non-PR group (91° [51, 174]). In the collapse group distal to the occluded segment, there was a normal-appearing vessel by IVUS that corresponded to the collapsed segment by CCTA; its minimum plaque burden was 33.2% [19.9, 38.1] with a smooth concave-shaped lumen surface, implying that the CCTA collapse segment was not occluded.ConclusionNot all CTOs are the same with regard to lesion remodelling and underlying morphology. The combination of IVUS and CCTA can help to categorize CTO morphology.

  • Interactions between mitral valve and left ventricle analysed by 2D
           speckle tracking in patients with mitral valve prolapse: one more piece to
           the puzzle
    • Authors: Huttin O; Pierre S, Venner C, et al.
      Abstract: AimsTwo-dimensional echocardiography often reveals abnormal left ventricle (LV) lateral wall kinetics in patients presenting with mitral valve prolapse (MVP). However, relations between MVP and LV deformation are not clearly established. The aim of this study was to assess and quantify mitral valve chordae, leaflets, and LV myocardial interactions using speckle tracking echocardiography (STE).Methods and resultsUsing STE-derived longitudinal strain curves, LV peak longitudinal strain (PLS, %), post-systolic index (PSI), and pre-stretch index (PST) were analysed in 100 patients with MVP and normal LV ejection fraction. Global, regional, and segmental values were compared according to mitral regurgitation severity and MVP location. Twenty healthy subjects served as control patients. There was no significant difference among control and MVP group for global and regional PLS (−23.7 ± 3.2 vs. −23.1 ± 2.2). In contrast, patients with MVP had significantly higher values of global PST (3.2 ± 4.1 vs. 1.3 ± 1.2; P = 0.01) and global PSI (3.2 ± 0.4 vs. 1.7 ± 1.1; P = 0.05) compared with controls, located mainly in the lateral wall and basal segments. Both anterior and posterior MVPs were responsible for PSI in basal inferior segments and PST in anterior ones. Mid-wall segmental deformation pattern changes were mainly observed at the level of the segments adjacent to the papillary muscle.ConclusionThis study supports the hypothesis that pathological early-systolic shortening and late systolic, post-systolic deformation are attributed to an increased interaction between wall deformation and mitral valve events in patients with MVP. STE is a useful tool in the assessment of interplays between MV leaflets and myocardium and helps to demonstrate changes in temporal pattern of myocardial deformation.

  • Echocardiographic arterial measurements in complex congenital diseases
           before bidirectional Glenn: comparison with cardiovascular magnetic
           resonance imaging
    • Authors: Krupickova S; Muthurangu V, Hughes M, et al.
      Abstract: AimsThis study sought to investigate diagnostic accuracy of echocardiographic measures of great vessels in patients before bidirectional cavopulmonary connection (BCPC) compared with cardiovascular magnetic resonance (CMR).Methods and resultsSeventy-two patients (61% after Norwood operation) undergoing BCPC between 2007 and 2012 were assessed pre-operatively using echocardiography and CMR. Bland–Altman analysis and correlation coefficients were used for comparison of echocardiography and CMR measurements. Sensitivity, specificity, and positive and negative predictive values were calculated to assess the ability of echocardiography to detect vessel stenosis. Twenty-four percent of all vessel measurements could not be made by echocardiography due to poor image quality. Acquisition of unsatisfactory images was higher in non-sedated patients. Although there was a reasonable correlation (0.68–0.90) and low bias (−0.8 to 0.5), there were wide limits of agreement between echocardiography and CMR demonstrating poor agreement. Sensitivity and specificity for pulmonary branches were moderate [sensitivity for right pulmonary artery (RPA) 67%, left pulmonary artery (LPA) 54%, specificity for RPA 65%, LPA 72%] with low levels of accuracy (RPA and LPA 42%). Sensitivity, specificity, and accuracy were better for aorta (82, 86, and 63%, respectively).ConclusionThis study demonstrates modest agreement between echocardiographic and CMR measures of vessel diameter and stenosis detection. Approximately a quarter of all vessel segments could not be measured using echocardiography due to poor image quality, which was significantly lower in non-sedated patients. These findings show that echocardiography cannot substitute CMR for reliable identification of great vessel stenoses in complex patients prior to the BCPC, particularly those with Blalock–Taussig shunts.

           quantify various types of coronary calcifications
    • Authors: Saita T; Fujii K, Hao H, et al.
      Abstract: AimsThis study evaluated whether optical frequency domain imaging (OFDI) could identify various coronary calcifications and accurately measure calcification thickness in comparison with histopathology.Methods and resultsA total of 902 pathological cross-sections from 44 coronary artery specimens of human cadavers were examined to compare OFDI and histological images. Histological coronary calcification was classified into four different types: (i) superficial dense calcified plates, (ii) deep intimal calcification, (iii) scattered microcalcification, and (iv) calcified nodule. The thickness of calcification was measured when both the leading and trailing edges of calcification were visible on OFDI. Of the 902 histological cross-sections, 158 (18%) had calcification: 105 (66%) were classified as superficial dense calcified plates, 20 (13%) as deep intimal calcifications, 30 (19%) as scattered microcalcifications, and 3 (2%) as calcified nodules. Superficial dense calcified plates appeared as well-delineated heterogeneous signal-poor regions with sharp borders on OFDI. Deep intimal calcifications could not be identified on OFDI. Scattered microcalcification appeared as homogeneous low intensity areas with indiscriminant borders. Calcified nodule, a high-backscattering protruding mass with an irregular surface, also appeared as a low intensity area with a diffuse border. The ROC analysis identified calcium thicknesses

  • Left atrial volume and strain parameters using echocardiography in a black
           population
    • Authors: Meel R; Khandheria BK, Peters F, et al.
      Abstract: AimsLeft atrial (LA) volume is an important predictor of morbidity and mortality in cardiovascular disease. Left atrial strain is a feasible technique for assessing LA function. The EchoNoRMAL study recently highlighted the possibility that ethnic-based differences may exist in LA size. There is a paucity of data regarding LA parameters in an African population. We sought to establish normative values for LA volumetric and strain parameters in a black population.Methods and resultsThis cross-sectional study comprised 120 individuals between 18 and 70 years of age. Left atrial volumes were measured by biplane Simpson's method, and strain parameters were measured using Philips QLAB 9 (Amsterdam, The Netherlands) speckle-tracking software. The mean age was 38.7 ± 12.8 years (50% male). Maximum LA volume indexed (LAVi), pre-atrial LAVi, and minimum LAVi were 19.7 ± 5.9, 12.2 ± 4.4, and 7.7 ± 3.2 mL/m2, respectively. Females had a higher LAVi compared with males (20.9 ± 6.3 vs. 18.6 ± 5.3 mL/m2, P = 0.04). Peak global longitudinal strain in the reservoir phase (ɛR) was 39.0 ± 8.3%, and the peak LA strain in the contractile phase (ɛCT) was −2.7 ± 2.5%. No gender differences were noted in ɛR. Body surface area, age, and weight were the main determinants of ɛR on multivariate linear regression analysis.ConclusionThe data reported in this study establish the normal reference values for phasic LA volumes and strain in a normal black population and serve as a platform for future studies.
