Catheter ablation effectively manages scar-related reentrant ventricular tachycardia in patients with structural heart disease by reducing arrhythmia recurrence and implantable defibrillator shocks.
This review outlines the pre-procedural planning, mapping, and ablation strategies for ventricular tachycardia in patients with structural heart disease.
Scar-related reentry is the most common mechanism of monomorphic ventricular tachycardia (VT) in patients with structural heart disease. Catheter ablation has assumed an increasingly important role in the management of VT in this setting, and has been shown to reduce VT recurrence and implantable cardioverter defibrillator (ICD) shocks. The approach to mapping and ablation will depend on the underlying heart disease etiology, VT inducibility and haemodynamic stability. This review explores pre-procedural planning, approach to ablation of both mappable and unmappable VT, and post-procedural testing. Future developments in techniques and technology that may improve outcomes are discussed.
