Methods: Forty-two patients with bifurcation lesions were included in our study. The primary endpoint was a 6-month MACE and angiographic stent patency was also evaluated by MS-CT coronarography. Results: Twenty-two patients (52.38%) were treated for acute coronary syndromes, 39 (92.85%) lesions were ''true bifurcations''. The 6-month clinical follow-up was performed in all patients.The 6-month MACE rate (cardiac death, myocardial infarction and target lesion revascularization) was 9.52% (95% CI: 2.66-22.62%); of these one patient (2.38%; 95% CI: 0.06-12.57%) died intensity projection; PCI, percutaneous coronary intervention; MACE, major adverse cardiovascular events; ISR, in-stent restenosis; TVR, target vessel revascularization; LM, left main stem; LAD, left anterior descending artery; RD, diagonal branch; LCx, left circumflex artery; OM, obtuse marginal branch; RCA, right coronary artery; PDA, posterior descending artery; SB, side branch; RAO, right anterior oblique view; LAO, left anterior oblique view.
