Abstract

Variations in the anatomy of the atrial septum can confound the transcatheter closure of atrial septal defects and patent foramen ovale. While lipomatous hypertrophy of the atrial septum is not frequently encountered, attempts to use standard atrial septal occlusion devices in such patient can lead to malapposition and continued shunt. Some operators have suggested that atrial septal hypertrophy is a relative contraindication to transcatheter-based closure techniques. We present a novel technique exploiting the features of the Amplatzer muscular ventricular septal defect occluder to treat atrial septal defects in the setting of lipomatous hypertrophy of the atrial septum in two patients.
