Abstract:
Objective To evaluate the acute and long-term results of stenting for left main coronary artery (LMCA) bifurcation lesions. Methods Forty consecutive patients with LMCA bifurcation lesion and normal left ventricular function were included. Sirolimus-eluting stents were performed in all patients. Results (1)The average diameter of LMCA was (0.81?0.48)mm before stenting and increased to (3.53?0.22)mm after stenting.(2)The procedural success rate was 100.0%. In-hospital events including stent thrombosis,Q-wave myocardial infarction,and emergency bypass surgery did not occur in any patients,and non-Q-wave MI in one patient (2.5%).(3)Clinical follow-up was obtained in all patients at (8.43?3.24) months. There were no death and no myocardial infarction during follow-up. The major adverse cardis events rate was 20.0%.(4)The angiographic follow-up rate was 67.5% (27 of the 40 eligible patients),and the restenosis rate was 18.5% (parent vessel only 11.1%,side branch only 3.7%,and both 3.7%).(5)Different type of operation had no influence on restenosis rate during angiographic follow-up. Conclusion Sirolimus-eluting stent implantation for LMCA bifurcation stenosis appears safe and effective with regard to acute and midterm complications.
