[Cardiac transplantation; results after 5 years].

After cardiac transplantation, long-term results were assessed in a group of 46 patients who survived more than 5 years after surgery. They were the survivors (50%) of a group of 92 patients who underwent transplantation before January 1990. On January 1995, mean follow-up was 82 +/- 14 months.

Early impairment of acetylcholine-induced endothelium-dependent coronary vasodilation is not predictive of secondary graft atherosclerosis.

Study Objective: To test the hypothesis that the magnitude of early constriction of coronary arteries to acetylcholine might be a useful predictor of secondary graft atherosclerosis.

Design: The responses of epicardial coronary arteries to stepwise intracoronary infusion of acetylcholine (10(-8)M to 10(-5)M) were compared in 7 control subjects and in 18 patients who had undergone transplants within 2 months after surgery.

Measurements And Results: Vessel dimensions (percent basal diameter) were measured by quantitative angiography.

[Cardiac surgery in chronic hemodialysed patients: immediate and long-term results].

Between 1979 and 1993, 50 patients (33 men and 17 women) receiving chronic haemodialysis, underwent 53 cardiac surgical procedures in the department. The mean age was 56 +/- 13 years. The average duration of preoperative dialysis was 82 +/- 63 months.

Donor/recipient aorta size mismatch in heart transplantation: a technical alternative.

A technical alternative is proposed to enable transplantation in cases of considerable size mismatch between donor and recipient aorta: interposition of a Dacron graft of intermediate diameter. This procedure was performed in a 56-year-old patient weighing 75 kg in whom a heart from a 40-kg donor was implanted.
