Right ventricular volume measurements were carried out in 20 patients after total correction of tetralogy of Fallot, 6 patients with a conduit and Hancock xeno-graft (G-1), S with an outflow patch (G-2), and 6 without or with a minimal right ventriculotomy and repair of pulmonary valve (G-3). Right ventricular end-diastolic volume index (RVEDVI) averaged 114±31, 155±57, and 115±28 ml/m2 in G-1, G-2 and G-3, respectively. Right ventricular ejection fraction (RVEF) averaged 0.42±0.11 in G-1, 0.53±0.04 in G-2 (p< 0.05, vs G-1) and 0.57±0.04 in G-3 (p<0.02, vs G-1).

14 patients in G-2 and G-3 were reorganized into G-A and G-B to evaluate right ventricular function with or without pressure overloading of the right ventricle. G-A consisted of 7 patients with right vent-ricular systolic pressure of more than 50 mmHg (74± 26) and G-B of 7 with those of less than 50 mmHg (39±4). There was no difference in RVEDVI and RVEF between G-A and G-B. RVEF was significantly lower in G-1 than G-A (p <0.02) and G-B (<0.05).

These results suggested that right ventricular pump function was depressed in patients with an extracardiac conduit between the right ventricle and the pulmonary artery.
