Key result
Catheter ablation techniques and indications for ventricular tachycardia depend heavily on the underlying pathophysiology, particularly in the setting of ischemic heart disease.
Why the study?
What are the indications and techniques for catheter ablation of ventricular tachycardia across different underlying pathophysiologies?
What are the indications and techniques for catheter ablation of ventricular tachycardia across different underlying pathophysiologies?
This review provides a comprehensive overview of the indications and techniques for catheter ablation of ventricular tachycardia based on underlying pathophysiology.
May inform substrate-specific VT ablation in ischemic disease; leaves open prospective trials to standardize indications across etiologies.
Ventricular tachycardia (VT) may be secondary to many different underlying pathophysiologies. The nature of the underlying disorder determines amenability to catheter ablation, thus, dictating the circumstances under which it should be undertaken. The differing substrates also influence the choice of techniques that are used. The most intensively studied clinical subgroup of VT is re-entrant VT in the setting of ischemic heart disease. The approach to ablation in such patients is discussed in detail. Subsequent discussion focuses on other clinically encountered varieties of VT and the ablation methods used in each individual disease state.
