Surgical angioplasty of the coronary trunks: an alternative to bypass techniques.
OBJECTIVE
To test the value of surgical angioplasty of the coronary trunks as an alternative to bypass techniques.


METHODS
Surgical angioplasty of the coronary trunks was performed in 12 patients (mean age 59 +/- 9 years), of whom nine underwent right coronary trunk angioplasty, five underwent left main coronary artery angioplasty, and two patients underwent bilateral coronary trunk angioplasty. A transpulmonary approach to the left main coronary artery was used. The patch consisted of saphenous vein in the first two patients but in the rest pericardium was preferred. Associated bypass procedures to the other coronary network using internal mammary or gastroepiploic arteries were performed in six patients, and one patient had a concomitant aortic valve replacement.


RESULTS
No early mortality (30-day) or morbidity was observed and all procedures were successful. A 15-day angiographic study revealed an excellent result in all 14 angioplasties. After 6 months, all patients were free of symptoms during exercise stress testing (maximum level of exercise 140 +/- 20 W). One patient with a recurrence of angina underwent a second operation after 1 year because of left anterior descending coronary artery occlusion after bilateral angioplasty. Another angiographic study was obtained after 1 year in three other patients, which showed excellent results (four angioplasties controlled). After a mean follow-up period of 17 +/- 7 months (range 6-31), all patients were symptom-free, and with the exception of the one reoperation, no cardiac events were reported.


CONCLUSIONS
Provided that contraindications (calcifications, involvement of the distal bifurcation) are respected, surgical angioplasty of the coronary trunks is safe, restores physiologic coronary perfusion, is economical with bypass material, and provides good results.
