Transcatheter occlusion of ventricular septal defect.

The patent ductus arteriosus occlusion device (Rashkind-USCI) was employed to occlude a residual ventricular septal defect after Fontan procedure in a patient with hypoplastic right ventricle, ventricular septal defect, and pulmonary stenosis. There was significant right-to-left shunting across the ventricular septal defect, with cyanosis exacerbated by exercise. After placement of the 17 mm occlusion device, the right-to-left shunt was markedly diminished, and the cyanosis resolved. Occlusion of ventricular septal defects in patients with complex congenital heart disease may be performed with the patent ductus arteriosus occluder in selected instances.
