Understanding lesion assessment and tissue response in PFA.
In this clip from Revolt Against the Ordinary: Transforming AF Outcomes Through Durable Lesions and Controlled Energy Delivery, Ivo Roca-Luque discusses the role of the PI index in evaluating lesion quality during pulsed field ablation.
He explains how the index incorporates multiple factors, including application number, contact stability and local impedance changes during energy delivery, providing insight into how tissue responds to ablation.
The discussion highlights how tissue response can complement procedural parameters, supporting interpretation of lesion formation and depth during PFA.
A practical perspective on emerging tools designed to support controlled energy delivery and durable lesion assessment.
