Abstract

PURPOSE: The internal thoracic artery (ITA) has shown increased production of nitric oxide, which has beneficial effects on ventricular remodeling, among conduits of coronary artery bypass grafting (CABG). However, little is known about the impact of bilateral ITA strategy on postoperative left ventricle (LV) reverse remodeling as compared with single ITA, especially in patients with severely impaired LV function. METHODS: We retrospectively reviewed 126 propensity-matched patients with advanced ischemic cardiomyopathy (ICM) (left ventricular ejection fraction
