Introduction
Saphenous vein graft (SVG) intervention remains technically challenging and is associated with higher rates of in-hospital morbidity and mortality compared with percutaneous coronary intervention (PCI) of native coronary arteriesarteries. This is largely because of the friable, degenerated atheromatous and thrombotic debris that develop when SVGs deteriorate. Progression of disease outside the stented segment can also lead to high rates of target vessel revascularization (TVR). The long-term clinical outcomes of first- (f-DES) and second-generation (s-DES) drug-eluting stents (DES) in SVGs has not been adequately studied.
Objective
To compare the long-term clinical results i.e target lesion revascularization (TLR) TVR and major adverse cardiac events (MACE) of f-DES and s-DES.
