More Than 25 Years of Experience With the Ross Procedure in Children: A Single-Center Experience

Background. Aortic valve replacement in children represents an important challenge. Concerns regarding pulmonary autograft and homograft longevity requiring reoperations are well recognized. Very long-term outcomes after the Ross procedure are still unknown. We reviewed our experience with the Ross procedure, aiming to define very long-term survival rate and freedom from reintervention. Methods. This was a single-center retrospective cohort including 63 consecutive children who underwent the Ross procedure. Median follow-up duration was 20.5 years. Time-related events were assessed using KaplanMeier estimator. Results. There were 51 (81%) boys, mean age 10.1 +/- 5.8 years. Isolated aortic stenosis was the most common diagnosis (n = 29, 46%) and 34 (54%) patients previously underwent cardiac surgery. There was 1 (1.6%) in-hospital death. Overall survival at 5, 15, and 25 years was 96.7%, 94.4%, and 94.4%, respectively. Freedom from any autograft-related reintervention was 98.1%, 86.4%, and 61.2% at 5, 15, and 25 years, respectively. Fifteen (24%) patients underwent autograft reoperations. Among them, 10 (67%) patients underwent valve-sparing autograft reoperation. Freedomfromany pulmonary conduit reintervention was 93.2%, 58.2%, and 28.3% at 5, 15, and 25 years, respectively. Thirty (46.6%) patients underwent conduit reintervention (8 percutaneous, 22 surgical replacements). Conclusions. The pediatric Ross procedure is associated with excellent long-term survival. Ross-related reinterventions are more than twice as common on the pulmonary homograft than on the autograft. (C) 2020 by The Society of Thoracic Surgeons.
