Navigating Risks in Arrhythmia Management: Safety and Therapy Options
This chapter delves into the complexities and safety concerns surrounding procedural therapy for severe heart conditions, focusing on VT ablation. It emphasizes the need for informed consent and careful consideration of both procedural and drug therapies, such as amiodarone, in treatment decisions.

Episode notes
Join CardioNerds EP Council Chair Dr. Naima Maqsood and Episode Lead Dr. Jeanne De Lavallaz as they discuss the results of the VANISH2 Trial with expert faculty Dr. Jeff Healey and Dr. Roderick Tung. Audio editing by CardioNerds academy intern, Grace Qiu.
The VANISH2 trial enrolled 416 patients with ischemic cardiomyopathy, an ICD in place, and recurrent episodes of sustained monomorphic ventricular tachycardia (VT) to receive either first-line VT catheter ablation or antiarrhythmic drug therapy with the primary composite outcome of death from any cause, appropriate ICD shock, ventricular tachycardia storm (meaning at least 3 ventricular tachycardia events within 24hrs) or treated ventricular tachycardia below the detection limit of the ICD. The study population had a mean age of 68 years, with 94% being men and predominantly of white ethnicity. On average, 14 years had elapsed since their last myocardial infarction, with approximately 60% having undergone percutaneous coronary intervention at the time. The mean ejection fraction was 34%.
