Key result
Catheter ablation procedures, aided by advanced imaging and electroanatomic mapping technologies, offer effective suppression of drug-refractory ventricular tachycardia in structural heart disease.
Technological advancements in imaging and mapping are enhancing the efficacy of catheter ablation for complex ventricular arrhythmias.
Supports ablation consideration in refractory VT; leaves open need for RCTs to confirm long-term benefits.
PURPOSE OF REVIEW: Drug-refractory ventricular tachycardia in the setting of structural heart disease results in frequent implantable cardioverter defibrillator therapies and an increased risk of heart failure. Management requires catheter ablation procedures for effective suppression of the arrhythmia. RECENT FINDINGS: Imaging and electroanatomic mapping technologies provide new insights into the myocardial structural abnormalities responsible for ventricular tachycardia. Integration of imaging data with three-dimensional mapping systems coupled with improved targeting of abnormal electrical signals may improve the ablation outcomes. New ablation tools show promise for the effective ablation of previously unreachable myocardial ventricular tachycardia circuits. SUMMARY: Catheter ablation procedures have evolved over the last 2 decades. Improved technology may contribute to more widespread utilization of catheter ablation in the future.
