[Conservative surgery in rheumatic aortic insufficiency].

The mechanism of rheumatic aortic regurgitation is retraction of the three cusps leading to lack of coaptation. The authors describe a technique of aortic valve repair by extension of the cusps using autologous pericardium, undertaken in 52 patients (mean age 21 +/- 5 years) and report the short and medium term results. There were no operative deaths or reoperation for technical failure.

[Correction by a calcium inhibitor of a coronary spasm occurring during aortocoronary bypass].

A case of recurrent coronary artery spasm after coronary revascularization under cardiopulmonary bypass is related. The spasm, which occurred under nitroglycerin perfusion, was suspected on the ECG tracing and confirmed during immediate reoperation. It was successfully treated with bepridil, a calcium-channel blocking agent.
