Determinants of incomplete left ventricular mass regression following aortic valve replacement for aortic stenosis

Abstract:

Objective: Incomplete regression of left ventricular hypertrophy (Abn‐LVMI) following AVR for aortic stenosis (AS) may decrease long‐term survival. In this prospective study, we identified the pbkp_redictors of Abn‐LVMI. Methods: Between 1990 and 2000, 529 patients undergoing AVR for AS had clinical and hemodynamic data collected prospectively. Preoperative and annual postoperative transthoracic echos were employed to assess left ventricular mass index (LVMI) and hemodynamics. Abn‐LVMI was defined as the 75th percentile of the lowest postoperative LVMI (>128 mg/m2, n = 133). All other patients were included in the normal regression group (N‐LVMI). Univariate and multivariable logistic regression analyses were used to determine the pbkp_redictors of Abn‐LVMI. Results: Preoperative hypertension, diabetes, coronary disease, valve size, mean postoperative gradients, effective orifice area, and patient …
