Subpulmonary obstruction from aneurysmal ventricular septum: In a child with dextrocardia and congenitally corrected transposition of the great arteries

Abstract

3-year-old boy underwent evaluation for dextrocardia. Echocardiograms showed features of corrected transposition physiology, a perimembranous, ventricular septal defect (VSD) (Fig. 1), and aneurysmal tissue beneath the pulmonary valve that caused severe subpulmonary stenosis (Figs. 2–4). Eighteen months after VSD closure and resection of the aneurysmal tissue, the patient was asymptomatic with only mild residual pulmonary outflowtract obstruction.
