Compatibility of a novel temperature‐controlled, irrigated radiofrequency catheter with ultra‐high‐density mapping

BACKGROUND: Compatibility of DiamondTemp (DT) radiofrequency (RF) catheter with the Rhythmia mapping system has not been manufacturer‐reported nor its tracking accuracy reported. METHODS: Consecutive patients undergoing macroreentrant atrial tachycardia ablation guided by Rhythmia and ablated using...

Sumario:BACKGROUND: Compatibility of DiamondTemp (DT) radiofrequency (RF) catheter with the Rhythmia mapping system has not been manufacturer‐reported nor its tracking accuracy reported. METHODS: Consecutive patients undergoing macroreentrant atrial tachycardia ablation guided by Rhythmia and ablated using DT were prospectively enrolled. Following catheter configuration, ablation lines were performed and remapped to measure the RF tag to effective‐ablation‐line‐center (RFT‐ALC) distance. RESULTS: Among 20 consecutive patients (54 maps), 40 ablation lines were evaluated. Overall, the RFT‐ALC distance was 3.88 ± 2.95 mm, and the operator assessment of accuracy was high. No complications occurred. CONCLUSION: The use of DT catheter guided by the Rhythmia mapping system is feasible and accurate.
