Radiofrequency catheter ablation for postinfarct ventricular tachycardia remains an adjunctive rather than primary therapy, with ongoing uncertainties regarding its long-term effectiveness.
Catheter ablation for postinfarct ventricular tachycardia remains an adjunctive therapy with uncertain long-term curative efficacy.
Continues to position ablation as adjunctive for postinfarct VT; leaves open long-term effectiveness for randomized trials.
Catheter mapping and radiofrequency ablation of postinfarct sustained ventricular tachycardia (VT) remain one of the greatest challenges for the electrophysiologist. Although there were no major breakthroughs during the past year, several refinements and clarifications of existing mapping criteria were published. In addition, initial reports appeared describing new mapping systems and ablation technologies that may significantly impact the way ablation studies are performed as well as the way in which they affect success rates. Uncertainties remain as to how effective catheter ablation will be as a longterm cure for this type of VT. For the foreseeable future, catheter ablation in postinfarct VT will remain adjunctive rather than primary therapy.

Miller et al. (1999) conducted a review in postinfarct sustained ventricular tachycardia. Radiofrequency catheter ablation was evaluated. Radiofrequency catheter ablation for postinfarct ventricular tachycardia remains an adjunctive rather than primary therapy, with ongoing uncertainties regarding its long-term effectiveness.
