[Percutaneous angioplasty of unprotected left main coronary disease with implantation of systematic stenting. Immediate and mid-term results].
The authors report the immediate and medium term results of percutaneous angioplasty of unprotected left main coronary disease with systematic stenting. Between March 1994 and December 1998, out of 6,006 patients undergoing coronary angioplasty, 92 had significant unprotected left main stem disease. The majority of patients was male (74 men, 80%) with an average age of 74.3 +/- 8.1 years. Between March 1994 and October 1996, only patients with a surgical contraindication were treated by angioplasty (n = 39). After October 1996, the indications were extended to patients who did not have surgical contraindications (n = 53). During the hospital phase, 4 patients (4%) died (ventricular arrhythmia: 1, cardiogenic shock: 2, gastro-intestinal haemorrhage: 1). No non-fatal infarction with or without Q waves were observed, and no emergency coronary bypass surgical procedures were required. The angiographic success rate was 100%. During follow-up (7.3 +/- 5.8 months), 6 other patients died, 13 required a repeat coronary angioplasty, 4 for restenosis of the left main coronary artery, and 2 underwent coronary bypass surgery. The actuarial survival rate was 89 +/- 5% at 1 year and 85 +/- 17% at 3 years. Percutaneous angioplasty for unprotected left main coronary disease with systematic stenting was performed with acceptable hospital and medium term results.
