revasc = revascularization, cd-TVR = clinically driven target vessel revascularization, CoCr-BP-BES = cobalt-chromium biodegradable polymer Biolimus A9-eluting stent, MACE = major adverse cardiac events, MI = myocardial infarction, POCE = patient-oriented composite endpoint, SS-BP-BES = stainless steel biodegradable polymer Biolimus A9-eluting stent, and TVF = target vessel failure.
