endocardial resection
Surgical removal of scarred or arrhythmogenic endocardial tissue to treat ventricular tachycardia.
Full Definition
Endocardial resection is a surgical technique used primarily in the treatment of ventricular tachycardia, particularly in patients with ischemic cardiomyopathy. The procedure involves the identification and removal of abnormal endocardial tissue, typically scar tissue from previous myocardial infarction, that serves as the substrate for reentrant arrhythmias. Using electrophysiologic mapping, surgeons identify the arrhythmogenic focus and perform precise resection while preserving viable myocardium.
Usage
Usage note: Distinguish from epicardial procedures; specify 'endocardial' to clarify the surgical plane.
