Longevity and Durability of Atrioventricular Valve Repair in Single-Ventricle Patients

Although significant AVVR developed in most patients within 1 year of repair, the need for repeat valve repair is relatively low if ventricular function is preserved. Ventricular function after repair did not predict late survival but was related to the longevity of AVV competence and subsequent risk for reintervention.
