The ventricular tachycardia (VT) catheter ablation procedure has evolved substantially in recent years. Progress in the field permits effective treatment of complex ventricular arrhythmias previously not amenable to catheter ablation.
Catheter ablation is now indicated for many patients with multiple VT morphologies, non-tolerated and non-sustained VTs that had been previously considered unmappable. Advances in mapping/ablation technology, including new energy sources for ablation and both contact and non-contact mapping systems, have been key to extending indications and improving outcomes.1 2 There is also increasing interest in pre-procedural and intra-procedural cardiac imaging techniques, such as intracardiac echocardiography (ICE), contrast enhanced cardiac magnetic resonance (CE-CMR), contrast enhanced multidetector CT (CE-MDCT) or positron emission tomography (PET-CT). These techniques can provide both anatomic and scar location/extent information. Although no trial data have shown that imaging can improve VT ablation results, its use is widely accepted in clinical practice (figure 1).
