1. Evaluation of Left Ventricular Systolic Function in Patients with Coronary Microvascular Dysfunction by Three-Dimensional Speckle-Tracking Imaging
Abstract Introduction: The objective of this study is to evaluate the left ventricular systolic function of patients with coronary microvascular dysfunction (CMD) using the three-dimensional speckle-tracking imaging (3D-STI) technique. Methods: From June 2018 to June 2019,72 subjects from Huzhou Central Hospital were enrolled, including 42 CMD in-patients

2. Subclinical Systolic Dysfunction during Chemotherapy for Breast Cancer
Abstract Background Cardiotoxicity is the main complication related to cancer therapy. Studies indicate that global longitudinal strain is an early detector of subclinical dysfunction of the left ventricle, preceding the decline in ejection fraction (EF). However, the reproducibility of such methodology has not been tested outside specialized centers. Obj

3. Longitudinal Shortening of the Left Ventricle by Cine-CMR for Assessment of Diastolic Function in Patients with Aortic Valve Disease
Resumo Fundamentos: A disfunção diastólica, comumente avaliada por ecocardiografia, é um importante achado precoce na maioria das cardiomiopatias. A ressonância magnética cardíaca (RMC) frequentemente requer sequências específicas que prolongam o tempo de exame. Recentemente, métodos de imagens com monitoramento de dados (feature-tracking) foram d

4. Risk of Obstructive Sleep Apnea and Echocardiographic Parameters
Resumo Fundamento: A apneia obstrutiva do sono (AOS) é um transtorno crônico, progressivo, com alta morbimortalidade e associado às doenças cardiovasculares (DCV), entre elas a insuficiência cardíaca (IC). As alterações fisiopatológicas relacionadas com a AOS podem impactar diretamente a função diastólica do ventrículo esquerdo. Objetivo: Esti

5. Presystolic Wave is Associated with Subclinical Left Ventricular Dysfunction Assessed by Myocardial Performance Index in Type 2 Diabetes Mellitus
Resumo Fundamento: O índice de performance miocárdica (IPM) avalia as funções sistólica e diastólica do ventrículo esquerdo. A onda pressistólica (OPS) é geralmente detectada no exame Doppler da via de saída do ventrículo esquerdo e seus possíveis mecanismos são complacência prejudicada e rigidez do ventrículo esquerdo. Objetivo: Investigar

6. Left ventricular noncompaction in a Para athlete
RESUMO O miocárdio não compactado é uma cardiomiopatia congênita caracterizada pela presença de trabeculações anormais no ventrículo esquerdo. O presente estudo descreve o caso de uma paratleta de goalball, 14 anos, sexo feminino, assintomática, com história pessoal de nistagmo congênito e leve deficiência visual, que apresentou alterações elet

7. Correlation between Exercise Stress Test and Echocardiographic Parameters in Elderly Individuals
Abstract Background: Maximum oxygen consumption (VO2 max) in healthy individuals decreases approximately 10% per decade of life, and such decrease is more pronounced after the seventh decade. Objectives: To assess functional capacity of individuals aged 75 years or older, submitted to ergometric test and transthoracic echocardiogram exam, by means of metab

8. Arrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia (ARVC/D) - What We Have Learned after 40 Years of the Diagnosis of This Clinical Entity
Resumo A cardiomiopatia/displasia arritmogênica do ventrículo direito (C/DAVD) foi inicialmente reconhecida como uma entidade clínica por Fontaine e Marcus que avaliaram um grupo de pacientes com taquiarritmia ventricular proveniente de um ventrículo direito (VD) estruturalmente comprometido. Desde então, houve avanços significativos na compreensão da

10. Late Follow-up of Patients Submitted to Total Cavopulmonary Derivation: Clinical Aspects, Reinterventions, and Complications Interfering in Morbidity and Mortality
Abstract Objective: To identify main complications in outpatient follow-up, as well as factors before or during operation that may interfere in patient's evolution. Methods: Retrospective study of patients submitted to total cavopulmonary shunt with extracardiac conduit from 2000 to 2014 at the Hospital do Coração (São Paulo, Brazil) and who underwent c

11. OPCABG for Moderate CIMR in Elderly Patients: a Superior Option?
Abstract Objective: To compare the early and late outcomes of off-pump coronary artery bypass grafting and coronary artery bypass graft + mitral valve repair in elderly patients with moderate chronic ischemic mitral regurgitation. Methods: One hundred and fifty elderly (age > 70 years) patients with moderate chronic ischemic mitral regurgitation who underw

12. Analysis of Dyssynchrony and Ventricular Function in Right Univentricular Stimulation at Different Positions
Abstract Introduction: Chronic stimulation of the right ventricle with pacemaker is associated with ventricular dyssynchrony and loss of contractility, even in subjects without previous dysfunction. In these patients, there is a debate of which pacing site is less associated with loss of ventricular function. Objective: To compare pacemaker-induced dyssync
