Little data are available on access strategy outcomes for cardiac catheterizations in patients with prior coronary artery bypass graft surgery (CABG). We investigated the effect of transradial access (TRA) and transfemoral access (TFA) on short-term major vascular complications (MVC) and long-term major adverse cardiovascular events (MACE). In this single-center, retrospective cohort study, 1084 patients met our inclusion criteria (TRA = 469; TFA = 615). The cumulative incidence for the primary safety endpoint MVC at 30 days (a composite of major bleeding, retroperitoneal hematoma, dissection, pseudoaneurysm, and arteriovenous fistula) was lower with TRA (0.7% vs 3.0%, P <.01) and this difference remained significant after propensity score adjustment (odds ratio: 0.24; 95% CI, 0.07-0.83; P =.024). The cumulative incidence for the primary efficacy endpoint MACE at 36 months (a composite of all-cause mortality, myocardial infarction, stroke, and urgent target vessel revascularization) was 28.6% with TRA and 27.6% with TFA, respectively. Kaplan-Meier curves showed no difference for the primary efficacy endpoint (P =.65). Contrast use (mL) was significantly lower with TRA (130 [100-180] vs 150 [100-213], P <.01). In conclusion, in patients with prior CABG, TRA was associated with significantly fewer short-term MVC and contrast use, but not with a difference in long-term MACE, compared with TFA.
