Vascular access site and outcomes in 58,870 patients undergoing PCI with a previous history of coronary bypass surgery: results from the British Cardiovascular Interventions Society National database

Mamas, Mamas; Nolan, James



Using the British Cardiovascular Intervention Society percutaneous coronary intervention (PCI) database, access site choice and outcomes of patients undergoing PCI with previous coronary artery bypass grafting (CABG) were studied.

Given the influence of access site on outcomes, use of radial access in PCI-CABG warrants further investigation.

Data were analyzed from 58,870 PCI-CABG procedures performed between 2005 and 2014. Multivariate logistic regression was used to identify predictors of access site choice and its association with outcomes.

The number of PCI-CABG cases and the percentage of total PCI increased significantly during the study period. Femoral artery (FA) utilization fell from 90.8% in 2005 to 57.6% in 2014 (p < 0.001), with no differences in the rate of change of left versus right radial use. In contemporary study years (2012 to 2014), female sex, acute coronary syndrome presentation, chronic total occlusion intervention, and lower operator volume were independently associated with FA access. Length of stay was shortened in the radial cohort. Unadjusted outcomes including an access site complication (1.10% vs. 0.30%; p < 0.001), blood transfusion (0.20% vs. 0.04%; p < 0.001), major bleeding (1.30% vs. 0.40%; p < 0.001), and in-hospital death (1.10% vs. 0.60%; p = 0.001) were more likely to occur with FA access compared with radial access. After adjustment, although arterial complications, transfusion, and major bleeding remained more common with FA use, short- and longer-term mortality and major adverse cardiac event rates were similar.

In contemporary practice, FA access remains predominant during PCI-CABG with case complexity associated with it use. FA use was associated with longer length of stay, and higher rates of vascular complications, major bleeding, and transfusion.
