Popis: | Background: /Purpose: Long-stenting, even with a second-generation drug-eluting stent (DES), is an independent predictor of restenosis and stent thrombosis in patients with long coronary lesions. Spot-stenting, i.e., selective stenting of only the most severe stenotic segments of a long lesion, may be an alternative to a DES. The purpose of this study is to compare the one-year clinical outcomes of patients with spot versus entire stenting in long coronary lesions using a second-generation DES. Method: This study is a randomized, prospective, multi-center trial comparing long-term clinical outcomes of angiography-guided spot versus entire stenting in patients with long coronary lesions (≥25 mm in length). The primary endpoint is target vessel failure (TVF) at 12 months, a composite of cardiac death, target vessel-related myocardial infarction, and target vessel revascularization (TVR). A total of 470 patients are enrolled for this study according to sample size calculations. This study will be conducted to evaluate the non-inferiority of spot stenting compared to entire stenting with zotarolimus-eluting stents (ZES). Results: This study is designed to evaluate the clinical impact of spot-stenting with ZESs for TVF due to possible edge restenosis or non-target lesion revascularization. Theoretically, spot-stenting may decrease the risk of TVR and the extent of endothelial dysfunction. Conclusion: This SPOT trial will provide clinical insight into spot-stenting with a current second-generation DES as a new strategy for long coronary lesions.
