Abstract

Background: Cardiac catheterization via the trans-radial approach (TRA) has shown several advantages over the trans-femoral approach (TFA) but with a concern of higher radiation exposure. Considering the growing experience with TRA, this study compares patient's radiation during coronary angiography using TRA versus TFA.

Methods: This study included consecutive patients undergoing coronary angiogram over a year at tertiary hospital performed by experienced operators through radial or femoral access. Parameters compared between the two routes included fluoroscopy time (FT), cineangiography time (CT), cini-sequences (CS), and patient radiation exposure quantified by Air Kerma (AK) and Dose Area Product (DAP).

Results: A total of 910 patients were studied, with 461 (50.6%) undergoing coronary angiography (CAG) via TFA and 449 (49.4%) via TRA. The mean age was similar between the femoral (54.07) and radial groups (53.7) years (P = 0.33), with slightly lesser proportion of males in the femoral group (74.62% vs 79.73%; P = 0.06). The mean (SD) DAP and AK were 15.71 (7.05) Gy·cm² and 258.3 (99.9) mGy for the femoral group, compared to 20.76 (9.48) Gy·cm² and 352.2 (151.5) mGy for the radial group (both P < 0.001). The mean (SD) FT, CT, and CS were 1.32 (0.94) minutes, 40.4 (9) seconds, and 5.93 (1.22) for the femoral group, compared to 2.19 (1.67) minutes, 44 (10) seconds, and 6.17 (1.26) for the radial group (all P < 0.01).

Conclusion: Coronary angiography via TRA is associated with increased patient's radiation. Future studies should investigate strategies to reduce radiation exposure in trans-radial procedures.

期刊介绍： Indian Heart Journal (IHJ) is the official peer-reviewed open access journal of Cardiological Society of India and accepts articles for publication from across the globe. The journal aims to promote high quality research and serve as a platform for dissemination of scientific information in cardiology with particular focus on South Asia. The journal aims to publish cutting edge research in the field of clinical as well as non-clinical cardiology - including cardiovascular medicine and surgery. Some of the topics covered are Heart Failure, Coronary Artery Disease, Hypertension, Interventional Cardiology, Cardiac Surgery, Valvular Heart Disease, Pulmonary Hypertension and Infective Endocarditis. IHJ open access invites original research articles, research briefs, perspective, case reports, case vignette, cardiovascular images, cardiovascular graphics, research letters, correspondence, reader forum, and interesting photographs, for publication. IHJ open access also publishes theme-based special issues and abstracts of papers presented at the annual conference of the Cardiological Society of India.
