Stent placement for ostial left anterior descending coronary artery stenosis: acute and long-term (2-year) results.
This study was performed to assess the acute and long-term results of elective stenting for the treatment of ostial left anterior descending coronary artery (LAD) stenosis. One hundred and eleven consecutive patients with ostial LAD stenting were included for this study. Follow-up angiography was performed at 6 months and clinical evaluation at regular intervals after stenting. Procedural success rate was 97.3%. Four patients developed non-Q myocardial infarction and one patient underwent emergency bypass surgery due to a large dissection after stenting. Angiographic restenosis rate was 26.1% (18/69), and target lesion revascularization rate 11.7%. The final luminal diameter after stenting was the only predictor of angiographic restenosis. Clinical follow-up was obtained in all patients at 21.5 +/- 16.0 months. Two patients died during the follow-up. Event-free survival rate was 84.6 +/- 3.8%. In conclusions, stenting with or without debulking atherectomy may be considered as an acceptable therapeutic option for the treatment of ostial LAD stenosis.
