Abstract

In conventional conduit operations, longevity has been essentially limited by the inevitable need for conduit replacement. This study was undertaken to compare long-term results of the use of equine pericardial conduits, autologous pericardial conduits, and direct anastomosis repair. Between 1982 and 2001, 366 patients underwent primary establishment of right ventricle-pulmonary artery continuity at our institution. The mean age at the time of operation was 6.2 years (range, 4 days to 28 years) and mean weight was 17.2 kg (range, 1.6 to 61 kg). Three different repair techniques were used for connection: hand-made valved equine pericardial conduits (n = 179), autologous pericardial conduits (n = 71), and direct anastomosis without a conduit (n = 116). Mean follow-up period for early survivors was 8.6 years in the equine group, 6.1 years in the direct anastomosis group, and 5.1 years in the autologous pericardium group. Direct anastomosis repair (p = 0.0002) was associated with significantly better freedom from late events (conduit replacement or late death) than equine pericardial conduits. The hazard ratio was less with the autologous pericardium conduit than with the equine pericardium, but the difference was not statistically...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.
