Surgical implications of atrial septal defect complicating aortic balloon valvuloplasty.
An 80-year-old man underwent percutaneous transluminal balloon valvuloplasty for critical aortic stenosis. The procedure was performed by the antegrade atrial transseptal approach and was complicated by a persistent atrial septal defect. Symptoms recurred 6 months later, restenosis of the aortic valve was confirmed, and the atrial septal defect yielded a substantially greater left-to-right shunt. This complication of percutaneous transluminal balloon valvuloplasty poses important problems in hemodynamic assessment and operative management of patients who undergo subsequent aortic valve replacement.
