Abstract

BACKGROUND: The outcomes of distal radial access (dRA) in chronic total occlusion percutaneous coronary intervention (CTO-PCI) have received limited study. METHODS: We compared the clinical, angiographic, and procedural characteristics of 120 CTO-PCIs performed via dRA access with 2625 CTO-PCIs performed via proximal radial access (pRA) in a large, multicenter registry. RESULTS: The dRA group had lower mean PROGRESS-CTO score than the pRA group (1.0 ± 1 vs 1.2 ± 1, respectively; P=.05), while J-CTO score (2.4 ± 1.2 vs 2.3 ± 1.3; P=.43) and PROGRESS-CTO Complications score (2.8 ± 1.8 vs 2.6 ± 1.9; P=.16) were similar in the dRA vs pRA groups, respectively. Technical success was similar in the 2 groups (90% dRA vs 86% pRA; P=.14). Concomitant use of femoral access did not alter procedural success. The incidence of major periprocedural adverse cardiac events was similar in the 2 groups (0.8% dRA vs 2.4% pRA; P=.26), whereas the incidence of tamponade requiring pericardiocentesis was lower with dRA (0% dRA vs 4.69% pRA; P<.001), as was air kerma radiation dose (median, 1.7 Gy; interquartile range [IQR], 0.97-2.63 Gy in the dRA group vs median, 2.27 Gy; IQR, 1.2-3.9 Gy in the pRA group; P<.001). CONCLUSIONS: Use of dRA in CTO-PCI is associated with similar procedural success and risk of complications as compared with pRA.
