Key result
F18-FDG Cardiac PET/CT and Technetium-99-m-MIBI SPECT were compared for assessing myocardial viability before CABG, but no quantitative results are reported in the abstract.
Why the study?
Preoperative myocardial viability defines outcomes in patients with poor LVEF undergoing CABG, making accurate preoperative assessment crucial for acceptable postoperative results.
Does F 18 -FDG Cardiac PET/CT compared to Technetium-99-m-MIBI SPECT improve the assessment of myocardial perfusion and viability in patients with poor LVEF before CABG?
Observational
Yes
Does F 18 -FDG Cardiac PET/CT compared to Technetium-99-m-MIBI SPECT improve the assessment of myocardial perfusion and viability in patients with poor LVEF before CABG?
This prospective multicenter study aims to compare F18-FDG PET/CT and Tc-99m-MIBI SPECT for assessing myocardial viability in patients with poor LVEF prior to CABG.
Answers are grounded in this paper and cite their sources.
Comparison of FDG-PET/CT and MIBI-SPECT for viability before CABG yields no quantitative results; leaves open whether either improves selection or outcomes in low-LVEF patients.
Objectives: Coronary artery bypass graft (CABG) surgery has been safely practiced on cases with poor left ventricular ejection fraction (LVEF). Although adversely effects of surgery with higher mortality and morbidity rates, preoperative myocardial viability defines outcome. Thus, it is crucial to determine preoperative left ventricular myocardial tissue viability for acceptable postoperative results in this group of patients. This multi-center prospective study focuses of assessment of myocardial perfusion and viability by comparison of two different nuclear medicine imaging techniques; technetium 99-m-methoxy-isobutyl-isonitrile single photon emission computed tomography (Technetium-99-m-MIBI SPECT) and cardiac fluorodeoxyglucose positron emission tomography-computed tomography (F 18 -FDG Cardiac PET/CT).
