    Abstract:
    OBJECTIVES: To report the incidence and predictors of moderate/severe radial artery spasm (RAS) in patients undergoing cardiovascular percutaneous procedures through a transradial approach (TRA) in centers with TRA expertise. BACKGROUND: Data regarding the actual rate of clinically meaningful RAS are limited due to difference in study designs and operator expertise. METHODS: The RAS registry, an international (14 centers from Argentina, Chile, India, Indonesia, Macedonia, The Netherlands and United States of America) registry that included 1,868 patients undergoing TRA cardiovascular procedures (63.5% diagnostic and 56.5% therapeutic).All selected centers used TRA as default strategy in the cardiac catheterization laboratory. Throughout 2012, each center included all consecutive TRA cases (during a 2-month period) into a dedicated database covering clinical characteristics as well as procedural topics related to TRA patterns and RAS occurrence. RESULTS: The incidence of moderate/severe RAS was 2.7%. Only 0.7% of patients required crossover (8 to transfemoral and 5 to contralateral TRA). Patients with moderately/severe spasm were more frequently females, had a history of dyslipidemia, received more often a 7F sheath and more puncture attempts than patients without spasm. By multivariate analysis, the need for more than one attempt and the use of a 7 F sheath were independent predictors of the development of moderate/severe RAS. CONCLUSIONS: The incidence of moderate/severe RAS is low in centers with a default TRA. Its development appears to be strongly related to the numbers of puncture attempts and the use of large sheaths.
