Why the study?
Does catheter endocardial mapping accurately localize the origin of ventricular tachycardia compared to intraoperative mapping in patients undergoing surgery?
Does catheter endocardial mapping accurately localize the origin of ventricular tachycardia compared to intraoperative mapping in patients undergoing surgery?
Catheter endocardial mapping is an accurate method for localizing the origin of ventricular tachycardia, predicting the site within 4-8 cm2 of intraoperative mapping.

May inform preoperative VT localization for surgery; leaves open validation against contemporary ablation systems.
