  • Cardiac Fatigue in Ultra-Marathon Runners Measured with Novel Techniques
           in Echocardiography

    • Authors: José Miguel Picco, Sebastián Wolff, Emanuel González Dávila, David Wolff
      Abstract: Introduction: Intense and prolonged physical exercise can produce physiological adaptations and acute changes in the cardiovascular system that have been the subject of study multiple times. In this context some authors speak that these acute and transient alterations would be attributable to cardiac fatigue.Objective: The objective of this work is to examine the echocardiographic changes observed in ultra trail athletes (mountainraces over 42 kilometers) pre and post effort, according to population characteristics (sex, age, weekly training load), usingtechniques of myocardial deformation by speckle traking.Material and methods: Twenty-eight participants were evaluated pre and post exercise (within one hour after exertion) using Doppler echocardiography and new echocardiographic techniques (post processing). Conventional descriptive statistics and comparative analysis were performed for paired data using a T test. Results: The median age of the patients was 38 ± 9 years with male predominance (N17 / 65%). In the baseline echocardiogram, we found preserved bi-ventricular systolic function,mean global longitudinal strain (GLS) of –19% ± 2, mean right ventricular free wall strain (FWSVd) –25% ± 3. In the Poststress evaluation significant alterations were observed when compared with the baseline echocardiogram data, such as dropin ejection fraction, decrease in GLS, FWSVd and increase in volume of you. Ventricular torsion was not affected. Conclusion:Post intense exercise is observed a decrease in myocardial deformation parameters measured by Speckle tracking, this is interpreted as cardiac fatigue induced by the exercise.

  • The Behavior of Regional Longitudinal Strain Depends on Coronary Flow
           Reserve in a Simultaneous Analysis during Dipyridamole Stress
           Echocardiography

    • Authors: Rosina Arbucci, Diego M. Lowenstein Haber, Ariel K. Saad, Graciela Rousse, Miguel Amor, Gustavo Zambrana, Daniela Sevilla, Sabrina Sciolini, Pablo M. Merlo, Jorge A. Lowenstein
      Abstract: Background: The behavior of regional and global longitudinal strain in relation to the value of the coronary reserve is poorlystudied.Objectives: Compare the behavior of the Apical and global longitudinal Strain with the value of the coronary reserve of theanterior descending artery and as a secondary aim compare these responses with the visual analysis of parietal motility duringEcho Stress with Dipyridamole.Materials and methods: Retrospective study of 179 patients (age 68.7±7.8), 90 patients (50.3%) were men. At the peak of thedipyridamole effect, the coronary reserve was measured, simultaneously with the Longitudinal Strain and the visual analisis ofcontractility. Two groups were divided: Group 1: Coronary reserve ≥2 and Group 2: <2. Apical Strain was defined as the averageof 4 apical segments and global as the average of the 17 segments. It was considered normal any increased of deformationResults: 113 patients (63.12%) were included in Group 1 and 66 (36.87%) in Group 2. Strain Apical: 96.77% of Group 1 increasedtheir strain values with the stress, while in group 2, 95.31% presented a worsening strain values (p<0.0001). Global Strain:82.8% of Group 1 had an increase in their values, while in Group 2, 78.8% showed worsening (p<0.01). Post Dipyridamoleparietal Motility Analysis: 96.46% of Group 1 had preserved parietal motility and only 54.5% of Group 2 (4 patients hadincreased apical Strain in this group).Conclusions: There was a close correlation between the coronary reserve of the anterior descending artery and the contractilereserve evaluated by regional apical longitudinal strain of the 4 apical segments, which was superior to the use of globalstrain. The Apical Strain showed a better correlation with ADA coronary reserve than with the visual analysis of contractility.

  • Usefulness of the Echocardiographic Calcium Score as Predictive Tool for
           Obstructive Coronary Artery Disease

    • Authors: Bruno J. Michelli, Suyai L. Bellandi, Federico G. Brachetta, Karen Knott, Karen J. Ferreyra, Antonio J. Alvez
      Abstract: Objectives: The aim of this study was to evaluate the predictive value of the echocardiographic calcium score (ECS).Methods: Ninety-six patients with coronary angiography indication were enrolled in the study: 20 with non-ST-segmentelevation acute coronary syndrome, 15 with chronic angina, 31 with ST-segment elevation acute coronary syndrome and 30asymptomatic patients. After echocardiography with ECS and correlation with coronary artery disease, patients were classifiedinto 2 groups according to ECS ≤1 or ECS ≥2.Results: Among the total number of patients, 23 patients without lesions had ECS: 0.61 and 73 with lesions had ECS: 2.63.In patients presenting lesions, 16 had single lesion with ECS: 1.68 and 57 multiple lesions with ECS: 2.87. In the 23 patientswithout lesions, 20 had ECS ≤1 and 3 ECS ≥2, and among the 73 patients with lesions, 13 had ECS ≤1 and 60 ECS ≥2. Thus,ECS ≥2 presented a higher frequency of coronary artery disease vs. ECS ≤1 (p <0.05), with 82.2% sensitivity, 87% specificity,95.2% positive predictive value and 60.6% negative predictive value. In single vs. multiple lesions, 9 out of 16 patientswith single lesion had ECS ≥2 and 51 out of 57 patients with multiple lesions had ECS ≥2, with 89.5% sensitivity and 43.8%specificity to identify multi-vessel disease, and 85% positive predictive value and 53.8% negative predictive value.Conclusions: The ECS would have good positive predictive value to assess coronary artery disease.

  • Lung Ultrasound in Cardiology: A Window to Pulmonary Edema

    • Authors: Elizabeth Hirschhaut Schor, Carmen Julia Delgado Mosquera, María Gabriela Cortez Montero
      Abstract: Pulmonary Ultrasound, a technique that has innovated the way of doing ultrasound and cardiology, basing the interpretationof the image on artefacts and modifying the diagnostic and therapeutic approach of patients with heart disease. The cardiologistcan perform pulmonary ultrasound with the transducer and echocardiography screen settings and must recognize the 4ultrasound patterns: Aerated / Dry Lung Pattern, Wet or Interstitial Lung, Pleural Effusion and Consolidation. The InterstitialPattern is the basis of the applications of this technique in the cardiological area, which are summarized in 7 clinical situations:differential diagnosis of dyspnea, heart failure syndrome, identification of acute respiratory distress, extreme situationssuch as high altitude edema, apnea diving and iron man, dialysis nephropaths, Acute coronary syndrome and alveolo-capillarystress ultrasound test. Cardiopulmonary ultrasound is proposed as mandatory and not optional for the cardiologist.

  • Long-term Non-invasive Hemodynamic Evaluation of Left Endocardial Cardiac
           Resynchronization Therapy

    • Authors: María Celeste Carrero, Gonzalo R. Díaz Babio, Gerardo Masson, Iván Constantin, Facundo Verón, Maria D. C. Mezzadra, Gustavo L. Vera Janavel, Pablo G. Stutzbach
      Abstract: Background: Cardiac resynchronization therapy has 25% to 30% rate of “non-responder” patients. Endocardial cardiac resynchronizationtherapy (eCRT), in which the left ventricular catheter is implanted in the endocardium, would be an alternativefor these patients; however, its long-term outcome has not been investigated.Objectives: The aim of this study was the long-term non-invasive hemodynamic evaluation of eCRT in clinical responders.Methods: Patients implanted according to the criteria for resynchronization, using the Jurdham technique, with more than 6months after the implant, were included in the study. All were clinical responders. The hemodynamic response was evaluatedwith a cardiac function analyzer, which measures the left ventricular systolic intervals (preejection and ejection periods) andautomatically calculates an index of systolic function and estimates the ejection fraction (Systocor mod ÍS100). To assess themechanical efficacy of eCRT, the cardiac function during biventricular mode was compared with left bundle branch block(LBBB), either spontaneous or by single stimulation of the right ventricle, with patients as their own controls. At least 20beats were averaged in each stimulation mode and only changes >1% with p <0.01 were considered as clinically relevantand statistically significant.Results: Seventeen patients were included, with a median follow-up of 43 months, (9 to 78 months). Endocardial resynchronization,compared with LBBB ventricular activation, showed that all patients shortened the preejection period by an average of31 ms (15%), indicative of decreased interventricular dyssynchrony caused by LBBB. In all patients, systolic function indexincreased by 0.3 (23%) and the EF by 8.3%. In 12/17 of cases (71%) the ejective period increased on average 8.7 ms (2.9%),suggesting an increase in systolic volume. In all changes p was <0.01.Conclusions: Endocardial resynchronization therapy offers significant long-term hemodynamic improvement, detected bysystolic intervals.

  • Two-dimensional Strain Echocardiography in the Evaluation of Ventricular
           Function in Patients with Newly Diagnosed Hereditary Hemochromatosis

    • Authors: J. Martín Aladio, Florencia Yamasato, Ariel K. Saad, Juan Sordá, Oscar Grosso, Esteban González Ballerga, Jorge Daruich, Sara Berensztein
      Abstract: Background: Hereditary hemochromatosis is a genetic disorder characterized by systemic iron overload which can involve theheart in advanced stages. Early myocardial involvement has not been thoroughly investigated.Objective: The aim of our study was to evaluate the performance of conventional Doppler-echocardiography and 2D strainechocardiography in a group of patients with newly diagnosed hereditary hemochromatosis vs. a control group.Methods: Patients with newly diagnosed hereditary hemochromatosis without treatment were included. All the patientsunderwent conventional Doppler echocardiography and 2D strain echocardiography with evaluation of left ventricular longitudinal,radial and circumferential strain, twist and torsion.Results: Twenty-three male patients with hereditary hemochromatosis (46±18 years) and 20 male controls (45±15 years)were included. There were no differences in ventricular dimensions and wall thickness. Left ventricular ejection fractionwas lower in patients with hereditary hemochromatosis (59±4% vs. 62±4%; p=0.01). There were no differences in MAPSE,TAPSE and left ventricular s’ velocity. There was a significant decrease in global strain in patients with hereditary hemochromatosis,with greater involvement of radial strain (37±12 % vs. 55±17%; p=0.01) and circumferential strain (-19.5±2.8% vs.-22.5±2.8%; p=0.001), and less involvement of longitudinal strain (-19±1.8% vs. -21.1±2.5%; p=0.04). Myocardial rotationshowed lower twist (17.7±13° vs. 25±7°; p=0.03) and lower torsion (2.3±1.8°/cm vs. 3.3±1.1 °/cm; p=0.03). There was nocorrelation between the different strain parameters and iron metabolism.Conclusions: Echocardiography, and particularly 2D strain analysis can detect early abnormalities of ventricular mechanicsin asymptomatic patients with systemic iron overload due to hereditary hemochromatosis.

      Abstract: Background: Longitudinal systolic strain (LSS) abnormalitiess have been described in patients with preserved ejection fraction(EF). The prognostic value of LSS in asymptomatic severe aortic stenosis (AoS) is under discussion.Objetive: The aim of this study was to assess whether LSS assessment using velocity vector imaging (VVI) predicts theprogression and indication of aortic valve replacement (AVR) in asymptomatic patients with severe AoS and preserved EF.Methods: The study included patients with severe AoS and preserved EF who were considered asymptomatic and withoutinitial indication for AVR. They underwent two, three and four-chamber echocardiography that evaluated LSS of each segmentand global longitudinal strain (GLS) by VVI, as well as NT-proBNP assessment. The primary endpoint was need for AVR.Results: A total of 57 patients with mean age 69±8 years, 49% women, were included in the study. After two years of follow-up,13 patients (22.8%) required AVR. This group had lower GLS (-15.5±3.4 vs.-18.9±3.1, p=0.03) and two-chamber LSS (-12.8±5.5vs.-16.3±5.6, p=0.04). In univariate analysis, GLS, NT-proBNP and the E/e’ ratio were predictors of the endpoint, while inthe multivariate analysis, only GLS was an independent predictor of need for AVR (HR: 1.28 (95% CI 1.04-1.58), p=0.01).Conclusions: Global longitudinal strain measured by VVI was an independent predictor of need for AVR

  • Left Atrial Function by Speckle Tracking in Liver Cirrhosis. A
           Cross-sectional Study

    • Authors: Zuilma Vasquez-Ortiz, Verónica Rendon-Bravo, Pablo Reyes-Hernández, Jorge Osequera-Moguel
      Abstract: Background: Cirrhotic cardiomyopathy is the systolic and/or diastolic dysfunction of the left ventricle at rest or stress, in theabsence of other cardiovascular conditions, and worsens the prognosis after transplant or other liver surgical procedures.Objective: The aim of the study was to characterize left atrial function with speckle tracking in cirrhotic patients.Methods: Ninety-nine consecutive patients with liver cirrhosis of different etiology were included in the study. All patientsunderwent rest echocardiographic evaluation with measurement of left ventricular and atrial function using traditionaltechniques, three-dimensional measurements and speckle tracking.Results: Median age was 50.9 years and 40% were men. No alterations of left ventricular systolic function were observed.Twenty-seven percent of patients had diastolic dysfunction and dilatation of the left atrium, the latter with a significantincrease according to the Child stage and left atrial pump function was altered in 29% of cases.Conclusion: Cirrhotic patients present left ventricular diastolic dysfunction and alterations of left atrial systolic functionmeasured by speckle tracking.

      Abstract: Background: Several specialized softwares are commercially available for the elective storage of stress echo (SE) data. Stateof-the-art SE is based upon novel parameters in addition to regional wall motion.Objective: To develop a novel software for SE data storage and reporting.Methods: We developed the prototype of a SE Comprehensive Software (SECS) with a minimum data set eventually allowingstandardized collection of data. The software runs with medium-low performance computers as well as with the most popularoperating systems (Windows, MAC OS and Linux). The export functions towards widely accepted formats allow easy data sharing.The software is able to generate a customized report which can be expanded in PDF and comma-separated value formats.Results: The program prototype data entry requires <2 min per study. The main pages focus on the 5 steps of ABCDE-SE: stepA (regional wall motion); step B (B-lines with 4-site simplified scan); step C (contractile reserve with force derived from systolicblood pressure and end-systolic volume); step D (Doppler-based coronary flow velocity reserve in left anterior descendingcoronary artery); step E (EKG-based chronotropic reserve measured as peak/rest heart rate). The final page graphically summarizesthe ABCDE information in a risk prediction model (cardiac death rate per year, from low risk <1% to high risk >3 %).Conclusion: SECS may provide a suitable infrastructure for an advanced clinical and research application, with simple graphicformat and convenient reporting option. It may represent a trade-off between exhaustive information required by scientificstandards and smooth workflow priority of busy, high volume, clinically-driven activities. Large scale validation and adaptationfrom users’ feedback is necessary prior to dissemination on demand.
