OBJECTIVES: We sought to understand the factors modulating left heart reverse remodeling after aortic valve replacement, the relationship between the preoperative symptoms and modulators of left heart remodeling, and their influence on long-term survival. METHODS: From October 1991 to January 2008, 4264 patients underwent primary aortic valve replacement for aortic stenosis. Changes in the time course of left ventricular reverse remodeling were assessed using 5740 postoperative transthoracic echocardiograms from 3841 patients. RESULTS: Left ventricular hypertrophy rapidly declined after surgery, from 137 ± 42 g/m(2) preoperatively to 115 ± 27 by 2 years and remained relatively constant but g..View full abstract
