Personalized External Aortic Root Support (PEARS) for Neo-aortic Valve Insufficiency After Arterial Switch Operation

Historically neo-aortic root dilatation following the arterial switch operation (ASO) has been managed with aortic root replacement with either a mechanical aortic prosthesis or valve-sparing operations in select patients with a salvageable valve (1). Both procedures require cardiopulmonary bypass (CPB), cardioplegic arrest and reimplantation of the coronaries. Anticoagulation for a mechanical prosthesis imposes a lifelong risk of thromboembolic and bleeding events and is a burden on patient quality of life.
