Angiographic stent thrombosis at coronary bifurcations: short- and long-term prognosis

摘要

Stent thombosis is a rare, but potentially fatal complication of percutaneous coronary intervention (PCI). Although premature discontinuation of dual antiplatelet therapy has been identified as the most common cause of angiographic stent thrombosis, technical misadventures also contribute to causation of stent thrombosis (ST) [1]. Inadequate stent apposition, malapposition or stent strut fractures have been associated with stent thrombosis. With the advent of better stent technology, such as thinner struts, easier deliverability, better visibility and more novel drug-coated stents have enabled interventional cardiologists to undertake PCI in patients with higher risk lesions. Bifurcation lesions are a much higher risk lesion subset. As newer
