Right Ventricular Diastolic Function 15 to 35 Years After Repair of Tetralogy of Fallot

Abstract

Isolated right ventricular restriction late after tetralogy of Fallot repair is common. Although it reflects abnormal hemodynamics, the A wave contributes to forward pulmonary arterial flow and shortens the duration of pulmonary regurgitation. Consequently, there is less cardiomegaly and improved exercise performance in those patients.
