Balloon aortic valvuloplasty: Treatment of rapid deployment aortic valve replacement complicated by a paravalvular leak.

ABSTRACT

The Edwards Intuity Elite valve system was designed to facilitate minimally invasive surgery and streamline complex aortic valve replacements and has since gained more popularity. Despite the superior results shown with rapid deployment aortic valve replacement (RDAVR) utilizing this valve system, paravalvular leaks (PVL), as a complication, remains a concern. Currently, there is no universally agreed single treatment option. A 53-year-old male with a history of well-controlled diabetes mellitus and hypertension presented to the emergency room with a 1-month history of angina, syncope on exertion and dyspnea. On further workup, he was found to have severe aortic stenosis in the setting of a bicuspid aortic valve, with non-obstructive coronary artery disease. He proceeded to urgent RDAVR with a 23 mm Edwards Intuity Valve. Six months post-RDAVR he re-presented with dyspnea on exertion and near syncopal episodes. Postoperative transthoracic and transesophageal echocardiography revealed moderate to severe PVL posterior to the prosthetic aortic valve. Balloon valvuloplasty with a 25 mm True Balloon was performed. Resolution of the PVL was confirmed postprocedure both by angiography and echocardiography. The patient was followed for 1 year and remained symptom-free with evidence of mild PVL on surveillance echocardiography. In conclusion, multiple treatment options for RDAVR complicated by PVL exist; however mid to long-term outcome data are lacking. We presented one such case successfully treated with balloon aortic valvuloplasty.
