Mapping of a postinfarction left ventricular aneurysm–dependent macroreentrant ventricular tachycardia

Year: 2015

Type: article

Abstract: Activation mapping of ventricular tachycardia (VT) is rarely accomplished owing to limited temporal and spatial resolution, unacceptably long mapping time, and hemodynamic instability.1 Entrainment mapping is a reasonable approach to identify targets for ablation in patients with tolerated postinfarction reentrant VTs; however, it often does not allow delineation of the entire VT circuit.2,3 Introduction of newer mapping technologies capable of rapid and high-resolution electroanatomic mapping may allow detailed activation mapping of macroreentrant VTs, enhancing our understanding of macroreentrant circuit geometry and electrophysiology to facilitate ablation.
