Efficacy of biventricular pacing on myocardial glucose metabolism in a patient with heart failure using 2-deoxy-2(18F)fluoro-d-glucose positron emission tomography: a case report

摘要

A 61-year-old-male with dilated cardiomyopathy and congestive heart failure was treated by implantation of a biventricular pacemaker. Myocardial glucose metabolism was evaluated by positron emission tomography with 2-deoxy-2[18F]fluoro-d-glucose (FDG) during atrial-right ventricular pacing or atrial-biventricular pacing. Percentage uptake of FDG decreased in the lower septal area of the left ventricle during right ventricular pacing, but the decrease was improved during biventricular pacing (74.7% vs 91.6%). Biventricular pacing may improve myocardial glucose metabolism in patients with congestive heart failure.
