Key result
Left ventricular endomyocardial biopsy via transradial access was successfully conducted in 37 consecutive patients with only one intraprocedural minor complication (ventricular fibrillation).
Why the study?
Is left ventricular endomyocardial biopsy via transradial access feasible and safe in patients with heart failure of unknown origin?
Observational (n=37)

Is left ventricular endomyocardial biopsy via transradial access feasible and safe in patients with heart failure of unknown origin?
Transradial access for left ventricular endomyocardial biopsy is a feasible and safe alternative to the traditional transfemoral approach for experienced operators.
Supports feasibility of transradial LV endomyocardial biopsy; leaves open need for comparative trials versus transfemoral.
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.

Schulz et al. (2015) conducted an observational in Heart failure of unknown origin (n=37). Left ventricular endomyocardial biopsy via transradial access was evaluated on Feasibility and safety (intraprocedural complications). Left ventricular endomyocardial biopsy via transradial access was successfully conducted in 37 consecutive patients with only one intraprocedural minor complication (ventricular fibrillation).
