Rhythm Interventions Online 2025 | On-Demand Sessions: Rhythm Interventions Online

This session, led by Devi Nair (Jonesboro, US), focuses on achieving safe and precise pulse field ablation and TEE guided left atrial closure within a low fluoroscopy workflow. The operator demonstrates how intracardiac echo and electroanatomical mapping can maintain contact assessment, lesion overlap and anatomic clarity when fluoroscopy is minimised. The panel discusses practical strategies for pulmonary vein isolation, the need for careful overlap on the roof and posterior wall and the impact of oedema on appendage anatomy. The case then moves to left atrial closure, where the value of selective fluoroscopy for device deployment, alignment and depth assessment is emphasised. Faculty explore how centres balance TE, ICE and limited contrast use to avoid compromising safety or device positioning. The discussion provides detailed procedural insights for combining PFA and LA closure efficiently while preserving imaging quality and procedural confidence.
