Anatomic repair of anomalies of ventriculo-arterial connection (REV). Results of a new technique in cases associated with pulmonary outflow tract obstruction.
From November 1980 to November 1986, 63 patients aged 4 months to 13 years (mean 3.4 years) underwent repair of anomalies of ventriculo-arterial connection with ventricular septal defect and pulmonary outflow tract obstruction, using a technique (REV) first described by us in 1982. The selection of patients was based on preoperative criteria, namely the measurement of the distance between the tricuspid and the semilunar valves. These measurements enabled us to select from patients with an abnormal ventriculo-arterial connection, those in whom the anomaly could be repaired by intra-ventricular partition alone. In the remaining cases, REV was indicated in the presence of pulmonary stenosis. The principles of the technique are: (1) resection of the infundibular septum creating a large, direct and subarterial communication between the left ventricle and the aorta; (2) construction of a straight left ventricle to aorta tunnel by intraventricular partition; (3) direct anastomosis of the pulmonary trunk to the right ventricle. There were 12 hospital deaths (19%). The mean follow-up was 32 months. One patient died suddenly 1 year after repair. Six patients required reoperation. All survivors are in NYHA class I, except for 3 patients who are in class II. No stenosis of the left ventricular outflow tract was found but 5 patients had a significant pressure gradient at the pulmonary outflow tract level. Our present experience suggests that in properly selected patients, REV allows anatomic repair in a wide variety of anomalies of the ventriculo-arterial connection associated with VSD and pulmonary outflow tract obstruction with an acceptable rate of mortality and morbidity.
