Twenty-five years of catheter ablation of ventricular tachycardia: a look back and a look
forward Page 1 Twenty-five years of catheter ablation of ventricular tachycardia: a look back …

Highlights•Postinfarction ventricular tachycardia (VT) caused by a reentrant circuit is an
important clinical problem.•Catheter ablation may not prevent VT because of difficulty in …

Background Mechanisms of scar-related ventricular tachycardia (VT) are largely based on
computational and animal models that portray a 2-dimensional view. Objectives The authors …

Worldwide,∼ 4 million people die from sudden cardiac death every year caused in more
than half of the cases by ischaemic cardiomyopathy (ICM). Prevention of sudden cardiac …

Arrhythmias originating in scarred ventricular myocardium are a major cause of death, but
the underlying mechanism allowing these rhythms to exist remains unknown. This gap in …

Background: Fast ventricular tachycardias (VTs) have historically been attributed to shorter
path lengths with smaller reentrant circuit dimensions in animal models. The relationship …

Objectives: This study reports the use of a novel “Lumipoint” algorithm in ventricular
tachycardia (VT) ablation. Background: Automatic mapping systems aid rapid acquisition of …

Background: After myocardial infarction, the infarct border zone (BZ) is the dominant source
of life-threatening arrhythmias, where fibrosis and abnormal repolarization create a …

Background: There has been increasing awareness of the 3-dimensional nature of
ventricular tachycardia (VT) circuits. VT circuits in patients with ischemic cardiomyopathies …

The fundamental hypothesis of substrate mapping for scar-mediated ventricular tachycardia
is that surrogates of the isthmus can be identified and targeted with ablation during sinus …
