Abstract:
PURPOSE: We investigated the operative outcome after bypass surgery in patients selected using viability criteria on F-18 FDG PET. MATERALS AND METHODS: Rest-24hr delay redistribution imaging of Tl-201 SPECT and F-18 FDG PET were performed in 11 patients. Seven of these 11 patients (6 men, 1 woman) were evaluated to have viable myocardium by F-18 FDG PET. Changes in symptoms and left ventricular ejection fraction (LVEF) after operation were evaluated. RESULTS: In seven of 11 patients, a significant amount of viable myocardium was found on F-18 FDG PET and Tl-201 SPECT. Severity of both chest pain and dyspnea improved markedly in all patients. Mean LVEF improved from 22% to 32%. CONCLUSION: F-18 FDG PET could be used to select the patients who will benefit from coronary artery bypass surgery.
