Right ventricular systolic function in organic mitral regurgitation: impact of biventricular impairment.
BACKGROUND To assess the prevalence, determinants, and prognosis value of right ventricular (RV) ejection fraction (EF) impairment in organic mitral regurgitation. METHODS AND RESULTS Two hundred eight patients (62±12 years, 138 males) with chronic organic mitral regurgitation referred to surgery underwent an echocardiography and biventricular radionuclide angiography with regional function a...
متن کاملAnterior chordal transection impairs not only regional left ventricular function but also regional right ventricular function in mitral regurgitation.
BACKGROUND Preservation of annuloventricular continuity through the chordae tendinae aims to maintain left ventricular (LV) function and thus improve postoperative prognosis. This study was designed to prospectively investigate the effect of anterior chordal transection on global and regional LV and right ventricular (RV) function in mitral regurgitation (MR). METHODS AND RESULTS Sixty-five p...
متن کاملThe impact of beta-blockade on right ventricular function in mitral regurgitation.
BACKGROUND Although mitral regurgitation (MR) results in left ventricular (LV) volume overload, right ventricular (RV) function may also be impaired. We investigated the influence of short-term beta-blockade on RV function in patients with moderate-severe MR. METHODS Twenty-six patients were randomised in a cross-over design to receive two weeks of beta-blockade or placebo. Echocardiography w...
متن کاملEchocardiographic Estimates of Right Ventricular Systolic Function in Dogs with Myxomatous Mitral Valve Disease
BACKGROUND Right ventricular (RV) dysfunction independently predicts outcomes in human myxomatous mitral valve disease (MMVD). There is limited information regarding RV systolic function in dogs with MMVD. HYPOTHESIS Right ventricular systolic function differs among stages of disease, decreasing in decompensated MMVD. ANIMALS Thirty-sixclient-owned dogs with MMVD not receiving oral cardiova...
متن کاملPapillary Muscle Function Does Not Predict Mitral Regurgitation in Patients with Normal Left Ventricular Systolic Function: A Transesophageal Echocardiographic Study
Objective: To evaluate LV papillary muscles (PM) function using transesophageal echocardiography (TEE), and to determine the relationship between PM function and mitral regurgitation in patients with normal left ventricular systolic function. Design: TEE examinations were prospectively performed. End diastolic and end systolic PM lengths were obtained from the transgastric long axis views and f...
