The presence of significant myocardial viable segments before revascularization will offer better prognosis with reduced mortality and morbidity. However, the usage of F18-FDG PET\/CT myocardial viability study in the presurgical risk stratification is limited.<\/jats:p>\n <\/jats:sec>\n \n Objective:<\/jats:title>\n The objective of the study is to predict perioperative mortality with hibernating viable myocardial (HVM) segments established by F18-FDG PET\/CT in comparison with EuroSCORE II in patients with LV dysfunction undergoing coronary artery bypass grafting surgery.<\/jats:p>\n <\/jats:sec>\n \n Materials and Methods:<\/jats:title>\n A prospective, observational study included 75 patients of chronic ischemic coronary artery disease with ejection fraction \u226440%. Tc-99m sesta-methoxyisobutylisonitrile myocardial perfusion single photon emission CT\/CT and myocardial viability with F18-FDG PET\/CT at rest were performed. Mortality risk stratification was done according to the EuroSCORE II. Patients were followed for post-coronary artery bypass graft surgery (CABG) 30-day mortality. Mortality observed by HVM segment groups were compared with EuroSCORE II predicted mortality.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n Receiver operating curve for 30-day mortality prediction with HVM segments and EuroSCORE II was constructed. It showed that a cutoff of <4 HVM segments (area under the curve [AUC] = 0.7) had a sensitivity of 85%, whereas EuroSCORE II (AUC = 0.4) had only 28.6% sensitivity. EuroSCORE II underestimated perioperative risk in patients with <4 viable segments, that is 5 times higher risk was observed in patients with <4 viable segments.<\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n HVM segments established by F18-FDG PET\/CT had independently predicted mortality postoperatively. Hence, including F18-FDG PET\/CT for viability assessment along with EuroSCORE II in preoperative risk assessment for revascularization by CABG in patients with LV dysfunction provided better risk stratification.<\/jats:p>\n
