OBJECTIVES: We aimed to investigate the feasibility and safety of @entity285 septal ablation (ASA) via transradial approach using a sheathless guiding catheter. BACKGROUND: Although ASA is conventionally performed via the femoral artery, there is a potential risk of @entity548 and other @entity455 . The transradial approach may be associated with a lower rate of such complications. A sheathless guiding catheter, with an advanced hydrophilic coating along its full length, could reduce radial @entity432 and @entity2473 . METHODS: We enrolled 14 consecutive @entity1 with @entity1121 treated with ASA via the radial access at Sendai Kousei Hospital from December 2012 to May 2014. Left radial access was used for the sheathless guiding catheter, while right radial access was used for monitoring left ventricular pressure with a 4 Fr diagnostic catheter. A temporary pacemaker was inserted via the right jugular vein. RESULTS: Procedural success rate was 93% (13/14 @entity1 ). The left ventricular outflow tract pressure gradient at rest was reduced from a median of 128 mm Hg (interquartile range, 49-147 mm Hg) at baseline to a median of 16 mm Hg (interquartile range, 13-26 mm Hg) at 30-day follow-up (P=.01). The New York Heart Association functional class improved from a median of II (II-III) at baseline to a median of I (I-I) at 30-day follow-up (P=.01). There were no cases of access-site complication, including radial @entity432 and @entity2473 . CONCLUSIONS: The transradial approach using a sheathless guiding catheter was feasible and safe for ASA.
