High-Density Mapping in Ventricular Tachycardia Ablation: A PentaRay® Study

摘要

BackgroundHigh-density mapping of ventricular tachycardia (VT) with PentaRay^® (Biosense-Webster) provides high resolution with discrimination of local abnormal electrograms and slow conducting channels. We evaluate the feasibility of PentaRay^® to characterize the anatomical substrate and assume an influence of the outcome despite limitations.
