Feasibility and Safety of Left Ventricular Endomyocardial Biopsy via Transradial Access: Technique and Initial Experience

Background: Endomyocardial biopsy constitutes an essential part of the diagnostic algorithm in patients with heart failure of unknown origin, but usually requires transfemoral access. Methods and Results: Here, we describe a novel method that allows interventional cardiologists to obtain left ventricular biopsies via transradial access with a 7.5F sheathless multipurpose (MP1.0) guiding catheter. This approach was successfully conducted in 37 consecutive patients at our institution with only one intraprocedural minor complication (ventricular fibrillation during insertion of the guiding catheter). Conclusions: Transradial access to obtain left ventricular endomyocardial biopsies is a feasible and safe option for experienced radial operators. (C) 2015 Wiley Periodicals, Inc.
