Background: In the recent years percutaneous treatment of the left main stem (LM) has gained a precise role as a result of consistent scientific evidence vs. coronary artery bypass. A self-apposing stent offers an improved adaptation to the vessel wall, especially in case of tapered vessels; aim of this study was to investigate the role of a novel self-apposing, sirolimus-eluting stent (Stentys, France) for the treatment of LM coronary artery disease. Methods and results: MATISSE is a retrospective, multicenter registry, which enrolled 151 patients treated with the device at 17 international centers. Primary study endpoint was the occurrence of major adverse cardiovascular events (MACE), a composite endpoint of cardiac death, target lesion revascularization (TLR) and target-vessel myocardial infarction, at 9 months clinical follow-up. Secondary endpoints included procedural success, the single determinants of MACE and stent thrombosis. Lesions were located in distal LM bifurcation in 84% of the patients. Procedural success was achieved in 150 patients. The average follow-up length was 348±52 days. MACE occurred in 14 (9.3%) patients with 2 (1.3%) cardiac deaths. TLR occurred in 8 patients (5.3%). There were 2 cases of definite stent thrombosis, 1 acute and 1 very late. Conclusions: a self-apposing stent, when used for LM PCI in a real world, high risk population, showed good immediate procedural results with low rates of adverse events at mid-term follow-up.

Abstract

Background: In the recent years percutaneous treatment of the left main stem (LM) has gained a precise role as a result of consistent scientific evidence vs. coronary artery bypass. A self-apposing stent offers an improved adaptation to the vessel wall, especially in case of tapered vessels; aim of this study was to investigate the role of a novel self-apposing, sirolimus-eluting stent (Stentys, France) for the treatment of LM coronary artery disease. Methods and results: MATISSE is a retrospective, multicenter registry, which enrolled 151 patients treated with the device at 17 international centers. Primary study endpoint was the occurrence of major adverse cardiovascular events (MACE), a composite endpoint of cardiac death, target lesion revascularization (TLR) and target-vessel myocardial infarction, at 9 months clinical follow-up. Secondary endpoints included procedural success, the single determinants of MACE and stent thrombosis. Lesions were located in distal LM bifurcation in 84% of the patients. Procedural success was achieved in 150 patients. The average follow-up length was 348±52 days. MACE occurred in 14 (9.3%) patients with 2 (1.3%) cardiac deaths. TLR occurred in 8 patients (5.3%). There were 2 cases of definite stent thrombosis, 1 acute and 1 very late. Conclusions: a self-apposing stent, when used for LM PCI in a real world, high risk population, showed good immediate procedural results with low rates of adverse events at mid-term follow-up.
