Key result

Catheter ablation of ventricular arrhythmias guided by the Advisor HD Grid catheter achieved acute success in 86% and short-term success in 73% of patients, with no procedural complications.

Why the study?

Minimal data existed on the Advisor HD Grid catheter and Precision electroanatomic mapping system for ventricular arrhythmia procedures.

Is catheter ablation guided by a high-density grid catheter and Precision EAM system safe and feasible for treating ventricular arrhythmias?

Population

22 patients (18 sustained ventricular tachycardia, 4 premature ventricular contractions)

Key Points

To evaluate the safety, feasibility, and procedural outcomes of catheter ablation for ventricular arrhythmias using a high-density grid catheter integrated with electroanatomic mapping.
Retrospectively analyzed 22 consecutive patients (18 with sustained ventricular tachycardia, 4 with premature ventricular contractions) undergoing ventricular arrhythmia ablation over a 12-month period.
Performed electroanatomic mapping of the left ventricle, right ventricle, and aorta using the Advisor HD Grid catheter with high-density wave mapping and best duplicate software.
Substrate mapping used a median of 1,700 points (IQR 1,427–2,412) in the left ventricle (n=13) and 1,435 points (IQR 1,114–1,871) in the right ventricle (n=11), achieving a 9% point utilization rate with a mean mapping time of 43 ± 17 minutes.
Acute procedural success was achieved in 86% of procedures, and short-term success was maintained in 73% of patients (16/22) at a median follow-up of 145 days (IQR 62–273 days), with zero procedural complications.
