Key result
A shared isthmus was identified in 43% (23 of 54) of pleiomorphic, hemodynamically tolerated ventricular tachycardias in postinfarction patients.

What is the prevalence of a shared isthmus in postinfarction patients with pleiomorphic, hemodynamically tolerated ventricular tachycardias?
Population
19 postinfarction patients with 54 pleiomorphic, hemodynamically tolerated ventricular tachycardias.

May support shared isthmus targeting in select cases; leaves open whether ablation outcomes improve in prospective studies.

What is the prevalence of a shared isthmus in postinfarction patients with pleiomorphic, hemodynamically tolerated ventricular tachycardias?
In postinfarction patients with pleiomorphic, hemodynamically stable VT, a shared isthmus is present in approximately 40% of VTs, providing a target for successful radiofrequency ablation.
Bogun et al. (2002) conducted an observational in Postinfarction with pleiomorphic, hemodynamically tolerated ventricular tachycardias (n=19). Radiofrequency ablation was evaluated on Prevalence of a shared isthmus. A shared isthmus was identified in 43% (23 of 54) of pleiomorphic, hemodynamically tolerated ventricular tachycardias in postinfarction patients.
