Area of Science:

  • Cardiology
  • Electrophysiology
  • Medical Imaging

Background:

  • Intramural premature ventricular complexes (PVCs) present a challenge for ablation.
  • Radiofrequency (RF) ablation may be ineffective for certain PVC morphologies.
  • Accurate visualization of coronary venous anatomy is crucial for targeted therapy.

Purpose of the Study:

  • To evaluate the clinical utility of the Fluoroscopy Integration Module (FIM).
  • To demonstrate FIM's role in guiding ethanol ablation for intramural PVCs.
  • To assess FIM's effectiveness in selecting target venous branches.

Main Methods:

  • Utilized the Fluoroscopy Integration Module (FIM) for real-time visualization.
  • Guided selection of target venous branches in patients with intramural PVCs unresponsive to RF ablation.
  • Administered ethanol ablation to selected venous branches based on FIM guidance and electroanatomic mapping data.

Main Results:

  • FIM successfully guided the selection of target venous branches for ethanol ablation.
  • Ethanol ablation was precisely targeted to areas identified via FIM and electroanatomic mapping.
  • This approach demonstrated efficacy in treating intramural PVCs where RF ablation had failed.

Conclusions:

  • The Fluoroscopy Integration Module (FIM) significantly enhances procedural precision for intramural PVC ablation.
  • FIM facilitates effective ethanol ablation by improving targeting accuracy.
  • The integration of FIM optimizes clinical success rates in managing complex PVCs.
