Transcatheter closure of a ventricular septal defect following myectomy for hypertrophic obstructive cardiomyopathy.

Post-operative ventricular septal defect (VSD) following septal myectomy in patients with hypertrophic obstructive cardiomyopathy (HOCM) is a rare complication which may warrant closure. Repeat early sternotomy for surgical closure of the VSD seems undesirable and transcatheter VSD closure may be a valid alternative. We report the case of successful closure of a 10-mm VSD following surgical therapy for HOCM using an Amplatzer Muscular VSD Occluder.

Transcatheter closure of a 22 mm patent ductus arteriosus with an Amplatzer atrial septal occluder.

Transcatheter techniques for closure of patent ductus arteriosus (PDA) have been used for almost 40 years. We report a case of a 24-year-old female with a 22 mm PDA, congestive heart failure, and atrial fibrillation. She underwent transcatheter PDA closure with an Amplatzer atrial septal occluder (ASO).
