title: [Treatment of ventriculo-pulmonary disconnections with prosthetic conduits. Long-term results].
abstract: Between 1973 and 1989, 81 consecutive patients aged 2 to 42 years old, with ventriculo-pulmonary discontinuity, were treated by implantation of prosthetic conduits. The initial pathology was Tetralogy of Fallot (33%), complete transposition of the great arteries (20%), truncus arteriosus (17%), double outlet right ventricle (17%) and atrioventricular discordance with L malposition of the great arteries (10%). The overall early mortality was 22% (18 cases) and 14% (5 cases) in the 36 patients operated after 1982. Sixty three patients were followed up for 3 months to 16 years; there were 8 late deaths which occurred spontaneously or at reoperation. Postoperative catheterisation was carried out in 33 cases; the average ventriculopulmonary systolic pressure gradient was 40 +/- 26 mmHg. Six patients were reoperated to change the conduit, on average 6 years +/- 23 months after the first operation. Five other patients underwent endoluminal dilatation of a stenosed conduit which delayed reoperation to change the conduit in 3 cases. Prosthetic conduits have been extensively used in patients with ventriculo-pulmonary discontinuity because they are readily available. However, because of progressive degradation of the prostheses between the 5th and 10th postoperative years, other therapeutic solutions should be considered, i.e. endoventricular repair when possible and, in other cases, the use of aortic homografts.
