Abstract:
Objective To evaluate the safety and efficacy of stenting in unprotected left main coronary artery lesions.Methods From December 2001 to April 2006,43 patients with mean ages of 62.79?11.26(45-86)years underwent unprotected left main coronary artery stenting.There were 4 cases(9.3%)with previous history of myocardial infarction,30 cases(69.8%)with hypertension and 5 cases(11.6%)with diabetes mellitus.Results Altogether 56 coronary stents were deployed in 43 patients.Isolated LMCA stenosis was found in 4 cases(9.3%),and in 39 patients(90.7%)there was multivessel disease in combination.There was ostial lesion in 11 cases(25.6%),and with mid shaftlesion in 6 cases(13.9%).Bifurcation lesion was found in remaining patients.Stents were successfully implanted into LMCA in 43 cases without complication during the procedure.In-hospital MACE developed in 2 cases(4.7%),including 1case of TLR(2.3%)and 1 death(2.3%).The patients were followed up for 2-53 months.MACE developed in 4 cases(9.5%),all were TLR.There were no significant difference in the rate of in-hospital and follow-up MACE,as well as recurring symptom among sites of the lesion.The cardiac event-free survival was 93.3% 6 months after PCI,89.4% 9 months after PCI,and 84.5% one year after PCI.Conclusion With the improvement of PCI strategies and intervention devices,coronary stenting can be safely applied for the treatment of LMCA lesions with satisfactory in-hospital and long-term outcomes in the experienced center.
