Key result
Noncontact mapping achieved a 100% acute success rate for guiding ablation of right ventricular outflow tract arrhythmias, which was higher than the success rate of a conventional approach.

Noncontact mapping may aid ablation of nonsustained RVOT arrhythmias; leaves open need for randomized comparison to conventional mapping.

Does noncontact activation mapping improve the success rate of catheter ablation in patients with RVOT tachycardia or ectopic beats compared to a conventional approach?
Noncontact mapping is a feasible and highly successful method for identifying the earliest endocardial activation and guiding ablation in RVOT arrhythmias, offering higher success rates than conventional approaches despite longer procedure times.
Ribbing et al. (2003) conducted an observational in Right ventricular outflow tract (RVOT) tachycardia and ectopic beats (n=33). Noncontact activation mapping vs. Conventional approach was evaluated on Acute success rate. Noncontact mapping achieved a 100% acute success rate for guiding ablation of right ventricular outflow tract arrhythmias, which was higher than the success rate of a conventional approach.
