P6520Outcomes of the trans radial approach PCI in a single tertiary center over a decade of adoption and

Abstract Background/Introduction The trans-radial approach (TRA) has been increasingly adopted for the use of percutaneous coronary interventions (PCI), with reported clinical benefits. Little is known regarding the change in outcomes over time. Purpose To assess the temporal trends of TRA PCI in a single tertiary center over a decade. Methods From a database of 21,763 consecutive PCI's, we analyzed 15,429 patients in 2 periods – 2008 to 2012 (period 1) and 2013 to 2017 (period 2). We examined the proportions of use of TRA, the influence on in-hospital outcomes and adjusted long-term effects. Results The rate of TRA rose from 15.9% in period 1 to 69.1% in period 2, including in specific situations such as acute coronary syndrome, chronic total occlusion, bifurcation, calcified lesions and unprotected left main PCI. In-hospital rates of bleeding were lower for TRA vs. TFA (1.8% vs. 5.1%, overall, p
