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 th...Continue Reading

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
