Abstract
We performed a literature search to identify the details of patients with right ventricular outflow tract obstruction caused by an aneurysm of the ventricular membranous septum in a perimembranous ventricular septal defect. Thirty-one cases with a median age of 29 years (range, 1-69 years) were studied. A right ventricle-pulmonary artery systolic pressure gradient ranged from 35 to 107 mm Hg (mean 69 mm Hg). An interventricular shunt was absent in eight patients: two children and six adults. It is necessary to monitor the size of an aneurysm of the ventricular membranous septum, whether or not an interventricular shunt is present.
