Abstract:
Perventricular device closure has become an important management adjunct for ventricular septal defects deemed inoperable and difficult to address in the catheterization laboratory. Complications directly related to the procedure are rarely reported, and all have been manifest in the periprocedural period. We present the case of a 6-week-old boy who underwent perventricular closure of a muscular ventricular septal defect and had a left ventricle pseudoaneurysm identified 10 months later during catheterization to close residual septal defects. We describe the subsequent percutaneous coil embolization of the pseudoaneurysm and clinical follow-up.
