    Abstract:
    BACKGROUND: The Lecompte (REV) procedure is used to correct abnormal ventriculoarterial connections in patients with congenital heart diseases; it avoids the need for an extracardiac conduit for pulmonary outflow tract reconstruction. The present study aimed to investigate effectiveness and criteria of the REV procedure in children with abnormal ventriculoarterial connections. METHODS: Thirty-eight children (mean age, (2.2 +/- 1.7) years; mean weight, (11.5 +/- 3.8) kg) with abnormal ventriculoarterial connections who had an REV procedure in our hospital from January 1998 to May 2006 were studied. Only 10 patients had the usual anteroposterior relationship of the two great arteries. The infundibular septum between the two semilunar valves was aggressively resected to enlarge it and construct a straighter left ventricular outflow tract and a wide tunnel between the ventricular septal defect (VSD) and the aorta. Eighteen cases had the original REV procedure; 20 had a modified REV procedure. RESULTS: All patients are alive; none developed severe complications. The postoperative right ventricular (RV) to left ventricular (LV) pressure ratio was 0.20-0.45. Five patients had RV dysfunction; 2 patients had a pressure gradient in the RV ventricular outlet of 30.0-34.5 mmHg; 3 cases had a 37.5-47.3 mmHg pressure difference in the RPA. All patients had an RV pressure less than half the systemic pressure. These gradients' magnitudes in all patients were consistent with the post-operative RV to LV pressure ratio (P < 0.05). During the follow-up (mean, (4.2 +/- 0.6) years), 2 patients had an RPA pressure gradient of 24.0-29.3 mmHg which abated to less than 10 mmHg after two years. CONCLUSIONS: The REV procedure provides satisfactory short- to medium-term results. It may be superior to the Rastelli procedure for treating ventriculoarterial connection abnormalities; it allows early, complete anatomic repair and reduces the need for late re-operation, since no extracardiac conduit is needed. Longer follow-up is needed to determine long-term outcomes.
