Effects of a Proximal Seal System on Neurologic Outcomes of Off-Pump Coronary Artery Bypass Grafting.

Effects of a Proximal Seal System on Neurologic Outcomes of Off-Pump Coronary Artery Bypass Grafting. Int Heart J. 2019 Apr 25;: Authors: Kim DJ, Lee SH, Joo HC, Yoo KJ, Youn YN Abstract Severe aortic atherosclerosis is a risk factor for stroke during coronary artery bypass grafting (CABG). The purpose of this study was to evaluate the incidence of postoperative neurologic complications after off-pump CABG (OPCAB) with a proximal seal system (Heartstring).From January 2011 to December 2014, 729 patients underwent isolated OPCAB. The cohort was divided into two groups (Heartstring [HS] and aortic no-touch [NT]). The severity of aortic atherosclerosis (Katz grade) was evaluated by intraoperative epiaortic ultrasonography (EUS). The primary endpoints were postoperative neurologic complications (early stroke and minor events (delirium, transient ischemic attack, and syncope) ), and the secondary endpoints were late major adverse cardiac and cerebrovascular events (MACCEs) and death.The mean age of all patients was 65.1 ± 9.5 years, and a severe Katz grade (IV or V) was demonstrated to be an independent risk factor of long-term mortality (HR 3.53; 95% CI 1.06-11.75; P = 0.04) and MACCEs (HR 2.41; 95% CI 1.19-4.92; P = 0.02), but no significant differences were found for early stroke (0.9% versus 1.7%; P = 0.53) and minor neurologic complications (14.6% versus 9.9%; P = 0.05) between the groups regardless of the Katz grade. The 5-year ove...
