title: Significant aortic regurgitation associated with transcatheter closure of perimembranous ventricular septal defects with a deficient aortic rim.
abstract: We report on two patients who developed significant aortic regurgitation during transcatheter closure of a perimembranous ventricular septal defect, both requiring further surgical intervention. Both patients were noted prior to the procedure to have limited subaortic margins to the defect. The potential mechanisms for development of aortic regurgitation in this setting are discussed.
