Letter by Berruezo et al regarding article, "Impact of local ablation on interconnected channels within ventricular scar: mechanistic implications for substrate modification".
BACKGROUND The extent to which channels within scar are interconnected is not known. The objective of the study was to evaluate the impact of local ablation of late potentials (LPs) on adjacent and remote areas of slow conduction with simultaneous multipolar mapping. METHODS AND RESULTS Analysis was performed on consecutive patients referred for ablation of scar-mediated ventricular tachycard...

متن کاملA 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...
متن کاملPrognostic Value of Scar Imaging for€Substrate Ablation of Ventricular€Tachycardia
SEE PAGE 353 C atheter ablation for ventricular tachycardia (VT) in ischemic heart disease is considered standard therapy in patients with recurrent, sustained monomorphic ventricular tachycardia, usually after failed antiarrhythmic therapy. Many centers worldwide use pre-procedural imaging with cardiac magnetic resonance (CMR) to assess the “scar substrate” in patients with ischemic and non-is...
متن کاملApplication of ripple mapping to visualize slow conduction channels within the infarct-related left ventricular scar.
BACKGROUND Ripple mapping (RM) displays each electrogram at its 3-dimensional coordinate as a bar changing in length according to its voltage-time relationship with a fiduciary reference. We applied RM to left ventricular ischemic scar for evidence of slow-conducting channels that may act as ventricular tachycardia (VT) substrate.
