Disadvantageous closure of the interventricular communication in double outlet right ventricle.

摘要

A double outlet right ventricle was diagnosed in a 10 week old infant, in whom the ventricular septum was intact at the time of presentation. A large aneurysm of a membranous septal remnant was present, and this appears to be the first recorded instance of closure of a malalignment ventricular septal defect by such a mechanism.
