Direct ablation and excision of myocardial scar in post-myocarditis ventricular aneurysm

Cardiac Aneurysm with Ventricular Tachycardia and Subsequent Excision of Aneurysm

W ITH the introduction of ventriculo11 plasty the importance of diagnosis of ventricular aneurysm has increased.1' 2 Prior to operation the subject of the following case report had episodes of ventricular tachycardia controlled with difficulty by continuous quinidine administration. Following excision of the ventricular aneurysm there were no further episodes despite the omission of quinidine. ...

Predictors of Success in Ablation of Scar-Related Ventricular Tachycardia

During ablation of re-entrant ventricular tachycardia (VT) 3-dimensional mapping systems are now used to properly delineate the scar tissue and aid ablation of scar-related VT. The aim of our study was to outline how the mode of ablation predicts success and recurrence in large scar-related VT. When comparing patients with recurrence and patients with no recurrence, univariate analysis showed t...

A Prospective Study of Ripple Mapping the Post-Infarct Ventricular Scar to Guide Substrate Ablation for Ventricular Tachycardia.

BACKGROUND Post-infarct ventricular tachycardia is associated with channels of surviving myocardium within scar characterized by fractionated and low-amplitude signals usually occurring late during sinus rhythm. Conventional automated algorithms for 3-dimensional electro-anatomic mapping cannot differentiate the delayed local signal of conduction within the scar from the initial far-field signa...
