The transradial approach during transcatheter structural heart disease interventions: a review. (February 2015) - Allende, Ricardo
Abstract Aims To review the safety and feasibility of a transradial (TR) approach during transcatheter structural or congenital heart disease interventions when utilized as either as a primary or secondary arterial access site. Methods and Results Studies and case reports published between 2002 and 2014 utilizing the TR access during transcatheter structural and congenital heart disease interventions during alcohol septal ablation (ASA), ventricular septal defect (VSD), renal denervation (RD), paravalvular leak (PVL) closure, transcatheter aortic valve implantation (TAVI, secondary access) and endovascular repair of aortic coarctation (ERAC, secondary access) were evaluated. Access‐site (femoral vs. TR) vascular and bleeding complications were assessed. Femoral access complications ranged from 0·16% to 40%, with an overall incidence of 2·2% (56/2521). There were 18 reports or studies specifically evaluating the utility of TR access in the context of transcatheter structural heart disease interventions (ASA: 3; VSD: 1; RD: 3; PVL closure: 1; TAVI: 7, ERAC: 3). The use of TR access either as primary or secondary access site was feasible and allowed the completion of the procedure in all cases. The overall incidence of access‐site complications following a TR approach was 0·5% (2/406 patients), with no major vascular or bleeding complications. Conclusions A TR approach during transcatheter structural heart disease interventions appears to be a safe, effective means of delivering high procedural success accompanied by lower bleeding complications compared with the transfemoral approach.
