Perioperative and Long-term Results With Mapping-Guided Subendocardial Resection and Left Ventricular Endoaneurysmorrhaphy
Key result
Mapping-guided subendocardial resection combined with endoaneurysmorrhaphy resulted in 0% operative or 30-day mortality and improved left ventricular function in patients with recurrent VT.
Why the study?
Does mapping-guided subendocardial resection combined with left ventricular endoaneurysmorrhaphy improve survival and reduce ventricular tachycardia inducibility in patients with coronary artery disease, left ventricular aneurysms, and malignant ventricular tachyarrhythmias?

Endoaneurysmorrhaphy with mapping-guided subendocardial resection safely and effectively treats recurrent ventricular tachycardia while improving left ventricular function in patients with LV aneurysms.
Cite This Study
Rastegar et al. (1996) conducted an observational in Recurrent ventricular tachycardia (n=25). Mapping-guided subendocardial resection and left ventricular endoaneurysmorrhaphy was evaluated on Operative or postoperative (30-day) mortality. Mapping-guided subendocardial resection combined with endoaneurysmorrhaphy resulted in 0% operative or 30-day mortality and improved left ventricular function in patients with recurrent VT.
