Differences in right and left ventricular remodeling after transcatheter closure of atrial septal defect among adults

Abstract

"Shrinkage" of the RV and "expansion" of the LV occurred soon after the procedure, even in elderly patients. Device closure of ASDs caused rapid improvement of LV function, but RV function underwent transient deterioration, probably due to delayed changes in RV ventricular mass in the face of acute volume reduction in this aged cohort.
