The conundrum of functional mitral regurgitation in chronic heart failure.
eart failure begets mitral regurgitation (MR); MR begets eart failure. This incestuous and insidious relationship has ong been known to contribute to the positive feedback loop hat underlies progressive, pathologic ventricular remodelng in chronic heart failure (CHF). Yet, despite decades of nvestigation and thought, important questions have gone nanswered, many with direct relevance to the car...
متن کاملAcute and chronic reduction of functional mitral regurgitation in experimental heart failure by percutaneous mitral annuloplasty.
OBJECTIVES We sought to determine acute and chronic efficacy of a percutaneous mitral annuloplasty (PMA) device in experimental heart failure (HF). Further, we evaluated the potential for adverse effects on left ventricular (LV) function and coronary perfusion. BACKGROUND Reduction of mitral annular dimension with a PMA device in the coronary sinus may reduce functional mitral regurgitation (...
متن کاملPercutaneous Treatment of Functional Mitral Regurgitation in Heart Failure
DOI: 10.5935/abc.20140143 Congestive heart failure (HF) remains one of the most important and challenging clinical problems in cardiovascular medicine in Brazil and worldwide. Evidence suggests that mortality in this setting has decreased in Brazil over recent years1, which may be related, at least partially, to a more intense and widespread use of neurohormonal blockade (with angiotensin-conve...
متن کاملSurgical management of functional mitral regurgitation in heart failure patients
Relevant secondary mitral regurgitation occurs in 35– 50% of patients with chronic heart failure and is associated with increased mortality. Surgical management of patients with mitral valve regurgitation and heart failure remains controversial. There are several questions which are not sufficiently clarified because of a lack of prospective randomised controlled trials: (1.) The indication for...
متن کاملEffect of cardiac resynchronization therapy on functional mitral regurgitation in heart failure.
Cardiac resynchronization therapy (CRT) reduces functional mitral regurgitation (MR) at rest. This study assessed exercise-induced changes in MR in patients with heart failure who were helped by CRT. The determinants of these exercise-induced changes in MR were analyzed in asynchronous and resynchronized left ventricles.
