Comparison of the Right and Left Distal Radial Access for Coronary Procedures

Abstract

Distal radial coronary access is effective. This study examined if the access location affects vascular access and procedure success. A prospective database was created to compare rDRA and lDRA using propensity score matching. “Access time, coronary procedure success, radial spasm, ionising radiation exposure, and patient comfort were observed. The rDRA and lDRA compared 182 of 385 procedures. Approach success was comparable (97.6%vs.97.6%, p=1.0), access time (sec) was shorter (39 (25-60)vs.50 (29-90); p=0.0026), and procedural success was 100% vs. 100% (p=1.000). Radial spasm was not statistically significant (2.2%vs.6.62%, p=0.150). There were no significant differences between the groups in dose-area product (32 (20-57.1) Gy.m2 vs. 32.5 (19.4-46.3) Gy.m2; p=0.487) or fluoroscopy time (min; 4.4 (2.6-9)vs.4.3 (2.5-7.5); p=0.215.”No study population had vascular access concerns. Those undergoing coronary procedures spent about same time in the catheterization laboratory after switching to the rDRA as they did with the lDRA, but the rDRA required less time to get access to the heart.
