Pulsed field ablation of the premature ventricular contractions originating from the medial free wall of the right ventricular outflow tract infundibulum: a case report.

ABSTRACT:

Background

Premature ventricular contractions (PVCs) originating from the infundibular region of the right ventricular outflow tract (RVOT) may be challenging to ablate due to thin myocardial wall and proximity to the coronary arteries in this region. In such anatomically sensitive regions, the use of radiofrequency (RF) energy may carry a risk of collateral injury or prove ineffective. We present a case report describing successful ablation of infundibular PVCs using pulsed field ablation (PFA).

Case summary

A 38-year-old female with highly symptomatic, monomorphic PVCs was referred for repeat ablation following a previously ineffective procedure performed with RF energy. Intracardiac mapping localized the earliest ventricular activation to the medial free wall infundibulum
