Fluoroscopy Integration Module Enhanced Localization of Intramural Premature Ventricular Complex in Ethanol Ablation.

Aims: The Fluoroscopy Integration Module (FIM) is a novel feature in electroanatomic mapping systems that enhances real-time visualization of coronary venous anatomy during mapping and ablation of intramural premature ventricular complexes (PVCs). This report demonstrates the clinical utility of FIM in guiding side branch vein selection and precise ethanol ablation targeting for intramural PVCs.

Methods and results: The target venous branch was selected under FIM guidance in patients with intramural PVCs where RF ablation failed. Ethanol was applied to the venous branch extending to the center of the intersection of ablation tags or early activation areas where transient suppression occurred.

Conclusion: The fluoroscopy integration module significantly improves procedural precision in targeting intramural PVCs, facilitating effective ethanol ablation and optimizing clinical success.
