1. Mortality Rates of Surgical Techniques for Correcting Atrioventricular Disjunction
Abstract We compared the mortality rates of two surgical techniques for correction of atrioventricular disjunction in 10 out of 720 patients who underwent mitral valve replacement from 2005 to 2012. In group I, the mitral annulus was fixed with bovine pericardial strips; in group II, a 'patch' of bovine pericardium was sutured and extended from the base of t

2. Approach to An Unusual Cardiac Mass: Mitral Annulus Caseoma
Abstract Caseous calcification of the mitral annulus (CCMA) is known to be a rare variant of mitral annulus calcification, a chronic and degenerative process of the mitral valve fibrous ring. It usually carries a benign prognosis. The following case demonstrates a huge mitral annulus caseoma that complicated with severe mitral regurgitation and was treated w

3. Reasons to Keep “Case Reports” Alive
Abstract Caseous calcification of the mitral annulus (CCMA) is known to be a rare variant of mitral annulus calcification, a chronic and degenerative process of the mitral valve fibrous ring. It usually carries a benign prognosis. The following case demonstrates a huge mitral annulus caseoma that complicated with severe mitral regurgitation and was treated w

5. Change in Functional Moderate Mitral Regurgitation after Aortic Valve Replacement
Abstract Objective: To evaluate the changes of the mitral valve geometrics and the degrees of moderate mitral regurgitation (MR) in patients undergoing aortic valve replacement (AVR) for aortic stenosis (AS). Methods: A retrospective analysis study of intraoperative transesophageal echocardiography (TEE) and postoperative transthoracic echocardiography (TT

6. Interleukin-6 contributes to myocardial damage in pregnant rats with reduced uterine perfusion pressure
Preeclampsia is one of the most frequent and difficult illnesses in pregnancy, which jeopardizes both mother and fetus. There are several diagnostic criteria for preeclampsia. However, the preeclampsia-associated myocardial damage has not been described. In this study, we employed reduced uterine perfusion pressure (RUPP) to generate a rat model of preeclamp

7. Mortality Predictors in the Surgical Treatment of Active Infective Endocarditis
Abstract Introduction: Active infective endocarditis is associated with high morbidity and mortality. Surgery is indicated in high-risk conditions, and the main determinants of mortality in surgical treatment should be evaluated. Objective: To identify mortality predictors in the surgical treatment of active infective endocarditis in a long-term follow-up.

8. Long-term Mortality Predictors in Patients with Small Aortic Annulus Undergoing Aortic Valve Replacement with a 19- or 21-mm Bioprosthesis
Abstract Introduction: Replacement of the aortic valve in patients with a small aortic annulus is associated with increased morbidity and mortality. A prosthesis-patient mismatch is one of the main problems associated with failed valves in this patient population. Objective: To evaluate the long-term mortality predictors in patients with a small aortic ann

9. Assessment of the left ventricular function in normotensive prediabetics: a tissue Doppler echocardiography study
ABSTRACT Objective Several studies have shown that left ventricular (LV) dysfunction is increased in individuals with diabetes. However, there are scarce data about LV function in prediabetics. This study assessed the early changes in LV diastolic and systolic myocardial function in normotensive prediabetics using tissue Doppler echocardiography (TDE). Su

10. Diastolic function is associated with quality of life and exercise capacity in stable heart failure patients with reduced ejection fraction
Exercise capacity and quality of life (QOL) are important outcome predictors in patients with systolic heart failure (HF), independent of left ventricular (LV) ejection fraction (LVEF). LV diastolic function has been shown to be a better predictor of aerobic exercise capacity in patients with systolic dysfunction and a New York Heart Association (NYHA) class

11. Análise morfofuncional cardíaca com o uso da ecocardiografia tridimensional em tempo real em indivíduos submetidos à plastia valvar mitral pela técnica de duplo teflon / Cardiac morphologic and functional analysis using real time tridimensional echocardiography in individuals submitted to mitral valve repair by double teflon technique
INTRODUCTION: Mitral valve repair is the treatment of choice to correct mixomatous mitral insufficiency. Tridimensional echocardiography studies demonstrate that mitral repair using prosthetic ring implant modifies mitral valve annulus morphology and function, although the literature related to mitral valve annulus behavior after mitral repair without use of

12. Efeitos da adição de sinvastatina ao enalapril em indivíduos hipertensos com níveis de colesterol limítrofe e disfunção diastólica: um estudo aleatorizado, controlado, duplo-cego, com ecocardiograma e Doppler tecidual de repouso e estresse / Effect of the addition of simvastatin to enalapril in hypertensive individuals with average cholesterol levels and diastolic dysfunction: a randomized, placebo-controlled, double-blind trial, with ecochardiography and tissue Doppler of rest and stres
Background: Diastolic dysfunction (DD) and decreased contractile reserve associated with hypertension are a surrogate for increased cardiovascular risk. Statins have experimental benefits on myocardial fibrosis, and could improve diastolic function or contractile reserve to a greater extend than ACE-inhibitors in hypertension. Objectives: Test in a double-bl
