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.
