(FIT)-Module 4 Workshop 6: Electrocardiographic and Electrophysiological Correlations-Gerstenfeld Case 4 Question

Video Transcription

Video Summary

A 45-year-old woman with a 25% burden of symptomatic Premature Ventricular Contractions (PBCs) and a reduced ejection fraction (EF) of 45% is considered for catheter ablation after metoprolol proves ineffective. Activation mapping indicates early activation sites in the anterior interventricular vein (AIV) and the left coronary cusp, but none in the right ventricular outflow tract. Before proceeding with ablation, an angiogram is conducted due to the proximity of coronary arteries. Options for management include ablating at reduced power, switching to cryoablation, ablating at a safe site, or terminating the procedure to try medication like flecainide.
