Key result
A map-directed regional surgical approach significantly reduced the recurrence of ventricular tachycardia compared to localized subendocardial resection (4% vs 38%, p=0.04).

Does a map-directed regional surgical approach reduce the recurrence of ventricular tachycardia compared to localized subendocardial resection in patients with ischemic heart disease?
Absolute Event Rate: 4% vs 38%
p-value: p=0.04
Krafchek et al. (1986) conducted a cohort in Recurrent sustained ventricular tachycardia or ventricular fibrillation (n=46). Map-directed regional procedure (excision and/or cryoablation) vs. Localized subendocardial resection was evaluated on Recurrence of ventricular tachycardia (p=0.04). A map-directed regional surgical approach significantly reduced the recurrence of ventricular tachycardia compared to localized subendocardial resection (4% vs 38%, p=0.04).
