13. Echocardiographic Correlation between Right Ventricular Function and Left Atrial Volume
Resumo Fundamentos: A relação entre a disfunção diastólica do ventrículo esquerdo (DDVE), seus achados mais importantes, como aumento do átrio esquerdo e hipertrofia ventricular esquerda (HVE), e a função do ventrículo direito (VD) tem pouca documentação na literatura científica. Objetivo: Avaliar a correlação entre o tamanho atrial esquerdo

14. 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

15. A practical approach to assess leg muscle oxygenation during ramp-incremental cycle ergometry in heart failure
Heart failure is characterized by the inability of the cardiovascular system to maintain oxygen (O2) delivery (i.e., muscle blood flow in non-hypoxemic patients) to meet O2 demands. The resulting increase in fractional O2 extraction can be non-invasively tracked by deoxygenated hemoglobin concentration (deoxi-Hb) as measured by near-infrared spectroscopy (NI

16. Respiratory Muscle Training Improves Diaphragm Citrate Synthase Activity and Hemodynamic Function in Rats with Heart Failure
Abstract INTRODUCTION: Enhanced respiratory muscle strength in patients with heart failure positively alters the clinical trajectory of heart failure. In an experimental model, respiratory muscle training in rats with heart failure has been shown to improve cardiopulmonary function through mechanisms yet to be entirely elucidated. OBJECTIVE: The present r

17. Cardiac rehabilitation program in patients with Chagas heart failure: a single-arm pilot study
Abstract: INTRODUCTION: The benefit of a cardiac rehabilitation (CR) program for patients with Chagas heart failure (CHF) remains unclear. Therefore, we aimed to investigate the effects of CR for CHF patients. METHODS: A single-arm pilot study, including 12 patients with CHF, was performed. Patients participated in an 8-month physical exercise interventi

18. Associated Clinical and Laboratory Markers of Donor on Allograft Function After Heart Transplant
Abstract Introduction: Primary graft dysfunction is a major cause of mortality after heart transplantation. Objective: To evaluate correlations between donor-related clinical/biochemical markers and the occurrence of primary graft dysfunction/clinical outcomes of recipients within 30 days of transplant. Methods: The prospective study involved 43 donor/rec

19. Early neonatal echocardiographic findings in an experimental rabbit model of congenital diaphragmatic hernia
This study aimed to demonstrate that congenital diaphragmatic hernia (CDH) results in vascular abnormalities that are directly associated with the severity of pulmonary hypoplasia and hypertension. These events increase right ventricle (RV) afterload and may adversely affect disease management and patient survival. Our objective was to investigate cardiac fu

20. Radiofrequency ablation can reverse the structural remodeling caused by frequent premature ventricular contractions originating from the right ventricular outflow tract even in a normal heart
OBJECTIVE: The aim of this study was to evaluate whether frequent premature ventricular contractions originating from the right ventricular outflow tract remodel the cardiac structure and function in patients with a “seemingly normal heart” and whether radiofrequency ablation can reverse this remodeling. METHODS: Sixty-eight patients with idiopathic f

21. Comparative study of electrophysiological parameters of endocardial septal stimulation with conventional endocardial pacing. / Estudo comparativo dos parâmetros eletrofisiológicos da estimulação endocárdica septal com a estimulação cardíaca endocárdica convencional.
Background: The conventional endocardial pacing in right ventricular apex or subtricuspid area causes significant QRS enlargement and important left ventricular desynchronization with ventricular function damage. By the introduction of RV bifocal pacing and the need of a less deleterious ventricular stimulation right ventricular septal pacing has been increa

22. Percutaneous closure of a post-traumatic ventricular septal defect with a patent ductus arteriosus occluder
OBJECTIVE: Ventricular septal defects resulting from post-traumatic cardiac injury are very rare. Percutaneous closure has emerged as a method for treating this disorder. We wish to report our experience in three patients who underwent percutaneous closure of a post-traumatic ventricular septal defect with a patent ductus arteriosus occluder. METHODS: We tre

23. Análise da função ventricular direita em dois protocolos de treinamento com bandagem ajustável do tronco pulmonar / Assessment of right ventricular function in two training protocols with adjustable pulmonary banding
The ideal surgical treatment of transposition of the great arteries is the Jatene operation during the neonatal period. If the neonate remains untreated for several reasons, the left ventricle may become unprepared to sustain systemic circulation. The preparation of the subpulmonary ventricle by pulmonary trunk (PT) banding is an option for the 2-stage Jaten

24. Influência da integridade dos barorreceptores nos ajustes morfofuncionais cardíacos à hipertensão espontânea em ratos / Influence of baroreceptor integrity on cardiac morpho-functional adjustments to spontaneous hypertension in rats
It has been demonstrated that reduced baroreflex sensitivity is an independent marker of mortality risk. The arterial baroreflex plays an important role in the maintenance of the moment-to-moment stability of blood pressure (BP). Although the contribution of blood pressure variability (BPV) to cardiovascular morbidity and mortality is well established, the m
