ABSTRACT

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 <0.001. Saphenous vein graft PCI was performed in 17% of patients with prior CABG surgery. Number of vessels treated was lower in patients with prior CABG surgery compared with patients without prior CABG surgery, 1.66 ± 0.56 versus 1.89 ± 0.64, respectively, p <0.001. Achievement of TIMI 3 flow post PCI and overall PCI success was similar in the two groups. Overall mortality at 30 days was similar in patients with prior CABG surgery compared with patients without prior CABG surgery, 6.75% versus 6.61%, respectively, p = 1.0. In conclusion, in this high-risk cohort of patients underwent hemodynamically supported PCI, prior CABG surgery was not associated with worse outcome. The use of hemodynamic support appears to mitigate the increased risk of PCI associated with prior CABG.
