Patients with prior coronary artery bypass grafting (CABG) represent a high-risk cohort given associated medical conditions and worse outcome of saphenous vein graft compared with native vessel percutaneous coronary intervention (PCI). The goal of the current analysis was to compare clinical outcomes in 591 patients with and without prior CABG and multivessel coronary artery disease or unprotected left main disease and severely reduced left ventricular systolic function underwent Impella supported PCI from the PROTECT II randomized trial and the cVAD Registry. Patients with prior CABG surgery (n = 201) were compared with those without prior CABG surgery (n = 390). The primary end point of this analysis was overall mortality at 30 days. Patients with prior CABG surgery had greater Society of Thoracic Surgery mortality score compared with patients without prior CABG surgery, 7.6 ± 6.4 versus 5.1 ± 5.5, respectively, p
