Key result
Surgery guided by intraoperative electrical activation mapping resulted in lower arrhythmia recurrence at 3 months compared to simple left ventricular aneurysm resection (17% vs 50%).

May reduce short-term recurrence after aneurysm resection; hypothesis-generating and requires randomized confirmation before practice change.
Cohort (n=65)
Does myocardial resection guided by intraoperative mapping reduce arrhythmia recurrence and improve survival compared to simple left ventricular aneurysm resection in patients with recurrent ventricular tachyarrhythmias?
Absolute Event Rate: 17% vs 50%
Surgery for ventricular tachycardia guided by intraoperative electrical mapping is more effective at eliminating arrhythmias and preventing arrhythmic death than blind left ventricular aneurysm resection.
Mason et al. (1982) conducted a cohort in recurrent ventricular tachyarrhythmias (n=65). Myocardial resection or incision guided by intraoperative electrical activation mapping vs. Simple left ventricular aneurysm resection was evaluated on Arrhythmia recurrence at 3 months. Surgery guided by intraoperative electrical activation mapping resulted in lower arrhythmia recurrence at 3 months compared to simple left ventricular aneurysm resection (17% vs 50%).
