Valve-sparing double root replacement after the Ross procedure

Abstract

Abstract An inherent limitation of the Ross procedure is long-term two valve disease which will require repetitive reintervention. In this case, a 31-year-old man who had underwent Ross operation due to congenital bicuspid valve 20 years before, underwent double root replacement: valve sparing root reimplantation concomitant with the right ventricular outflow tract (RVOT) reconstruction with a bioprosthesis for severe RVOT stenosis. Although the diameter of autograft root was 42 mm and aortic insufficiency was mild, we added root surgery due to concerns regarding autograft root dilation in response to left ventricular volume load after RVOT reconstruction. The postoperative echocardiogram showed minimal aortic valve regurgitation and normal blood flow in the RVOT, and he was discharged from the hospital on the 17th day after the surgery. In this report, we present the outcomes of Valve-sparing double root replacement following Ross surgery.
