Aortic valve replacement in patients with severe aortic regurgitation and reduced left ventricular ejection fraction.
Aortic Regurgitation and Reduced Left Ventricular Ejection Fraction To the Editor: Chaliki et al1 have presented data in patients with severe aortic regurgitation (AR) with normal left ventricular (LV) ejection fraction (LVEF 50%; n 73). “Mild” LVEF reduction (35% to 50%; n 134) and “markedly” low LVEF ( 35%; n 43) who were operated on between 1980 and 1995. In February of 1980,2 we documented ...
متن کاملEffect of Preoperative Ejection Fraction
Ninety-three patients with aortic valve disease were evaluated to determine the effect of the preoperative left ventricular ejection fraction (EF) on the results of aortic valve replacement (AVR). Forty-six patients had aortic stenosis (AS), 16 had aortic insufficiency (Al), and 31 had mixed aortic stenosis and insufficiency (MX). Immediate and long-term survival curves in AS and MX, and in AS ...
متن کاملImpact of preoperative left ventricular ejection fraction on long-term survival after aortic valve replacement for aortic stenosis.
BACKGROUND The survival of patients who undergo aortic valve replacement (AVR) for severe aortic stenosis with reduced preoperative ejection fractions (EFs) is not well described in the literature. METHODS AND RESULTS Patients undergoing AVR for severe aortic stenosis were analyzed using the Northern New England Cardiovascular Disease Study Group surgical registry. Patients were stratified by...
متن کاملPreoperative left ventricular ejection fraction and left atrium reverse remodeling after mitral regurgitation surgery
BACKGROUND Left atrium enlargement has been associated with cardiac events in patients with mitral regurgitation (MR). Left atrium reverse remodeling (LARR) occur after surgical correction of MR, but the preoperative predictors of this phenomenon are not well known. It is therefore important to identify preoperative predictors for postoperative LARR. METHODS We enrolled 62 patients with chron...
متن کاملInfluence of preoperative left ventricular contractile reserve on postoperative ejection fraction in low-gradient aortic stenosis.
BACKGROUND Dobutamine stress hemodynamics (DSH) has the potential to stratify operative risk in low-gradient aortic stenosis (AS), but little is known about the relation between left ventricle contractile reserve and postoperative left ventricular ejection fraction (LVEF). We sought to assess the value of DSH to predict postoperative improvement in LVEF. METHODS AND RESULTS Sixty-six consecut...
