Long-term angiographic and clinical outcome of patients undergoing multivessel coronary stenting.
BACKGROUND
Randomized clinical trials have shown that multivessel coronary angioplasty is feasible and provides similar long-term survival as bypass surgery in selected patients. However, the higher need for repeat intervention, in particular, coronary artery bypass graft surgery, remains a problem. The objective of this study was to test the hypothesis that multivessel stenting is safe and effective in reducing the need for repeat interventions, in particular, the need for bypass surgery.


RESULTS
Between March 1993 and June 1995, 100 consecutive patients (243 lesions) had multivessel coronary stenting. High-pressure stent optimization was used in all patients. Procedural success was achieved in 97% of lesions; 2 patients (2%) required emergency bypass surgery. Angiographic follow-up was obtained in 89% of patients at 5.2+/-2.5 months. Angiographic restenosis occurred in 22% of the lesions, but 37% of patients had > or = 1 lesion with restenosis. Clinical follow-up was obtained in all patients at 21 +/- 10 months: target lesion revascularization was needed in 30 patients (30%), repeat angioplasty in 28 patients (28%) and coronary bypass surgery in 2 patients (2%); the overall survival rate was 96% (2% noncardiac death).


CONCLUSIONS
Multivessel coronary stenting can be performed with high success rate and low need for emergency bypass surgery. Compared with historical results with multivessel percutaneous transluminal coronary angioplasty, patients who undergo multivessel stenting need less repeat interventions, in particular, less coronary bypass surgery and have similar long-term survival.
