Catheter ablation flutter series#
This case series shows that HD-VGM mapping can quickly localize and terminate an atypical flutter circuit. ConclusionsĪblation of atypical atrial flutter is challenging and time consuming. 17.7 ± 7.7 min, p = 0.0021), and success in termination of the arrhythmia during the procedure (100 vs. In comparison to the control cohort, the study cohort had a shorter procedure time (135 ± 46 vs. With a mean follow-up 16 ± 9 months, 90% are in normal rhythm. The mean procedure time was 135 ± 46 min. A mean of 195 ± 75 s of radiofrequency (RF) energy was needed to terminate the arrhythmias. An average 3D anatomic mapping time of 12.39 ± 4.71 min was needed to collect 2996 ± 690 total points and 1016 ± 172 used mapping points. Twenty-six different atypical flutter circuits were evaluated. The results were compared to 21 consecutive historical control patients who had undergone an atypical flutter ablation without HD-VGM. HD-VGM was performed with a commercially available impedance-based mapping system to locate and successfully ablate the critical isthmus of each tachycardia circuit. Twenty-one patients presenting with 26 different atypical atrial flutter circuits after a previous catheter or surgical AF ablation were studied. This study aims to describe a novel method of High Density Activation Sequence Mapping combined with Voltage Gradient Mapping Overlay (HD-VGM) to quickly localize and terminate atypical atrial flutter.
