Abstract:
Tetralogy of Fallot with restrictive ventricular septal defect and suprasystemic right ventricular pressure is an uncommon anomaly with high mortality rate. Very few such cases have been reported pre-operatively. This report describes echocardiographic features of five patients with restrictive ventricular septal defect due to flap valve in tetralogy of Fallot. In all the five cases, accessory or excessive tricuspid valve tissue obstructed the defect. Recognition of restrictive ventricular septal defect in tetralogy of Fallot is important because it appears to have poor prognosis.
