Idiopathic Ventricular Tachycardia

Idiopathic ventricular tachycardia (VT) is an important cause of morbidity and less commonly, mortality in patients with structurally normal hearts. Appropriate diagnosis and management are predicated on an understanding of the mechanism, relevant cardiac anatomy, and associated ECG signatures. Catheter ablation is a viable strategy to adequately treat and potentially provide a cure in patients that are intolerant to medications or when these are ineffective. In this review, we discuss special approaches and considerations for effective and safe ablation of VT arising from the right ventricular outflow tract, left ventricular outflow tract, left ventricular fascicles, papillary muscles, and moderator band.

Automated summary

Idiopathic ventricular tachycardia (VT) is a significant cause of morbidity and sometimes mortality in patients with structurally normal hearts. Proper diagnosis and treatment rely on understanding the mechanism, cardiac anatomy, and associated ECG patterns. Catheter ablation is an effective strategy for patients who cannot tolerate medications or when medications are ineffective. This review discusses specific approaches and considerations for safely and effectively ablating VT arising from various locations.
