Differential Regurgitation in Branch Pulmonary Arteries After Repair of Tetralogy of Fallot

Abstract

PR after repair of TOF is commonly associated with differential regurgitation in the branch pulmonary arteries, which is usually greater in the LPA. Although the cause of this disparity requires further investigation, those patients with a significant unilateral contribution to total PR may be amenable to localized techniques to reduce regurgitation.
