The Impact of a Residual Atrial Communication in Patients Undergoing Complete Repair for Tetralogy of Fallot: A Propensity Score Matched Analysis

Surgeons may leave a residual atrial-level communication during complete repair of Tetralogy of Fallot (TOF) in anticipation of restrictive right ventricle physiology or as routine practice. We investigated the impact of closing the interatrial communication at the time of definitive TOF repair.
