Pulmonary Valve Function Late After Ross Procedure in 443 Adult Patients

Abstract

Background: Limited data exist on long-term pulmonary valve function after the Ross procedure. This study sought to determine the long-term function of the pulmonary valve in 443 consecutive adult patients who underwent a Ross procedure. Methods: All 443 patients who underwent a Ross procedure between November 1992 and March 2018 were reviewed retrospectively. All underwent pulmonary valve replacement using a cryopreserved pulmonary allograft. Freedom from the study's outcomes were calculated using Kaplan Meier survival. Risk factors for valve failure were analyzed using Cox regression. Results: Mean age at time of operation was 39 years (range: 15-66 years). There was 1 (0.2%, 1 of 443) ope..
