Figure 3: Post-Operative Reverse Remodeling

The LV volume (A) and EF (B) were calculated with the area-length method. 1 week, 1 month, 6 months, 1 year, and 2 years indicate 1 week, 1 month, 6 months, 1 year, and 2 years after mitral surgery, respectively. The dotted line in the graphs indicates the number of remaining survivors was less than one-half of the initial number of patients (i.e., more than one-half died at that time). *Significantly different from baseline (Pre). #Significantly different from the prior study. D/L (C) = ratio of left ventricular diameter and length; EF = ejection fraction; ESWS/ESVI (E) = end-systolic wall-stress per indexed end-systolic volume (mm Hg/ml/m2); Mass (D) = indexed LV mass (g/m2); MR = mitral regurgitation; Pre = pre-operative baseline data.
