Follow-up of small muscular ventricular septal defects after surgical closure of large ventricular septal defect

ABSTRACT

Background: closure of ventricular septal defects [VSDs] in infancy due to pulmonary hypertension has greatly replaced pulrnonary artery banding. This approach has been extended to infants with multiple VSDs, closing large VSD and in many cases leaving small muscular VSDs behind. The hemodynamic relevance and rate of closure of these VSDs are unknown. The purpose of this study was to assess the outcome of infants with multiple VSDs after surgical closure of a large VSD leaving another small muscular VSD [s] behind
