Safety and feasibility of a systematic transradial-access program for percutaneous coronary intervention in chronic total occlusions

Abstract Aims To evaluate the safety and feasibility of a transradial-access PCI program in CTO and its impact on angiographic and clinical results and in-hospital stay length. Methods Retrospective single-centre cohort-study including 237 consecutive patients undergoing CTO-PCI. From November 2018 onwards, a transradial-access program and all first-attempt CTO-PCI procedures were systematically performed via the radial artery. 47 patients included in the transradial-access CTO-PCI program were compared to a historical cohort of 190 CTO-PCI patients, employing transfemoral access mainly: n=150 (78.9%). Results Mean age was 66.9±11.4 and 199 (83.9%) patients were male, Table 1. Mean J-CTO score (2.5±1.1) was similar in both groups. Successful revascularization was achieved in 208 (87.8%) cases overall, without differences between both cohorts. No differences in periprocedural complications between both groups existed, but in-hospital complications were numerically lower in the transradial cohort (4.3% vs 13.7%, p=0.072). Mean hospital-stay was lower in the transradial-access group (0.89±1.4 vs 2.2±3.2 days, p<0,001). Same-day discharge was successfully accomplished in 56% of elective patients in the transradial-access program, Figure 1. Conclusion A transradial program for CTO-PCI is safe and effective in most CTO. Adoption of a transradial protocol for CTO-PCI allows same-day hospital discharge in over half of elective procedures and reduces in-hospital stay length. Figure 1.
