Pacing-Correctable Mitral Regurgitation
Mitral valve regurgitation (MR) is a rather common finding in heart failure (HF) patients with ischemic or nonischemic cardiomyopathy. MR is a progressive disease as it causes chronic left ventricular (LV) volume overload, increases right ventricular (RV) pressure, and thereby accelerates the progression of LV dysfunction and HF. There is ample evidence about the close relationship existing bet...

متن کاملContractile response and mitral regurgitation after temporary interruption of long-term cardiac resynchronization therapy.
AIMS Cardiac resynchronization therapy (CRT) utilizing biventricular pacing (BVP) is a promising treatment modality for symptomatic patients with chronic left ventricular (LV) systolic dysfunction and intraventricular conduction delay. Clinical studies have shown short-term improvement in contractile function and mid-term improvement in clinical status with CRT. The objective of this study was ...
متن کاملLate development of mitral regurgitation after left ventricular reconstruction surgery.
PURPOSE Late presence of mitral regurgitation (MR) after the Dor procedure (left ventricular (LV) reconstruction associated with coronary artery bypass grafting) for postinfarction patients carries a poor prognosis. The aim of this study was to review our experience with the Dor procedure and to analyze the correlation of surgical results with late MR. METHODS The study group comprised 19 pat...
متن کاملCellular and ventricular contractile dysfunction in experimental canine mitral regurgitation.
This study was designed to answer two questions. First, does the left ventricular contractile dysfunction resulting from mitral regurgitation (MR) reflect a primary defect in the cardiac muscle cell? Second, what is the basis for any change in cellular contractile function that might be observed? Left ventricular volume overload was produced in 10 dogs by catheter transection of mitral chordae ...
