INTRODUCTION: Minimal data exists on the Advisor™ HD Grid (HDG) catheter and the Precision™ electroanatomic mapping system (EAM) for ventricular arrhythmia (VA) procedures. Using the HDG catheter the EAM uses the HD wave mapping and best duplicate software to compare the maximum peak-to-peak bipolar voltages within a small zone independent of wavefront direction and catheter orientation. The study aimed to summarise the procedural experience for VAs using the HDG catheter. METHODS: Clinical and procedural characteristics of VA ablation procedures were retrospectively reviewed that used the HDG catheter and the Precision™ EAM over a 12-month period. RESULTS: Twenty-two patients, 18 with sustained ventricular tachycardia and 4 with premature ventricular contractions were included. Clinically indicated left and/or right ventricular (LV, RV, respectively), and aortic maps were created. LV substrate maps (n=13) used a median 1700 points (IQR25-75% 1427-2412) out of a median 18,573 (IQR25-75% 15,713-41,067) total points collected. RV substrate maps (n=11) used a median 1435 points (IQR25-75% 1114-1871) out of a median 16,005 (IQR25-75% 11,063-21,405) total points collected. Total point utilisation, used vs collected, was 9%. Mean mapping time was 43±17mins (substrate 34±18mins; activation/pace mapping 9±13mins). Acute success was achieved in 56 (86%) and short-term success achieved in 16 patients (73%) at median follow up of 145 days [IQR25-75% 62-273 days]). There were no procedural complications. CONCLUSION: HD wave mapping using the novel HDG catheter integrated with the Precision™ EAM is safe and feasible in VA procedures in the LV, RV and Aorta. Mapping times are consistent with other multi-electrode mapping catheters. This article is protected by copyright. All rights reserved. This article is protected by copyright. All rights reserved.
