Serial multidetector computed tomography assessment of left ventricular reverse remodeling, mass, and regional wall stress after restrictive mitral annuloplasty in dilated cardiomyopathy.

Abstract

Our findings indicate that ventricular reverse remodeling occurs soon after restrictive mitral annuloplasty.

In contrast, myocardial reverse remodeling (ie, regression of myocardial hypertrophy) occurs over time between the early and late postoperative periods.

Our data also suggest that the late improvement in left ventricular systolic performance might be attributable to a decrease in the left ventricular afterload.
