Abstract:
Objective To evaluate the immediate and long-term outcomes of left main bifurcation lesions using different stenting techniques.Methods 27 patients undergone unprotected left main coronary artery stenting had been analyzed.14 cases with simple stenting techniques and 13 cases with complex stenting techniques were involved.Results 40 coronary stents were deployed in 27 patients.The procedural success rate was 100%.No major adverse cardiac events(MACE)had developed in hospital.More true bifurcation lesions were involved in complex stenting group than in simple stenting group(84.6% vs 14.3%,P=0.0004),as well as multivessel lesions involved(100% vs 57.1%,P=0.0074).The residual ostial restenosis of left anterior descending artery(LAD)in complex stenting techniques group was more than that in simple stenting techniques group((4.29±4.25)vs(10.85±5.51),P=0.002).The residual ostial restenosis of left circumflex artery(LCX)in complex stenting group was less than that in simple stenting group((4.61±3.01)vs(13.63±11.21),P=0.009).The patients were followed up for 2～53 months.Angina pectoris recurred in 3 cases(11.1%)and target lesion revascularization(TLR)developed in 2 cases(7.41%).The total MACE happened in 2 cases(7.41%).There was no significant difference between complex stenting group and simple stenting group about symptom recurrence(7.1% vs 15.4%,P=0.59)and TLR(0 vs 15.4%,P=0.13).Conclusion Both simple and complex stenting techniques are feasible with better in-hospital and long-term outcomes.
