Wall thickness‐based adjustment of ablation index improves efficacy of pulmonary vein isolation in atrial fibrillation: Real‐time assessment by intracardiac echocardiography

Ablation index (AI) linearly correlates with lesion depth and may yield better therapeutic performance in pulmonary vein isolation (PVI) when tailored to a patient's wall thickness (WT) in the left atrium (LA).
