Positron emission tomography (15O-water 11C-acetate 11C-HED) risk markers and nonsustained ventricular tachycardia in hypertrophic cardiomyopathy

摘要

The objectives of the study were to describe positron emission tomography (PET) parameters, using the tracers O-water at rest/stress, C-acetate, and C-HED, with regard to nonsustained ventricular tachycardia (NSVT) in hypertrophic cardiomyopathy (HCM). PET offers quantitative assessment of pathophysiology throughout the left ventricular segments, including the endocardium/epicardium. The potential use PET in risk stratification remains to be elucidated. NSVT provides a marker for sudden cardiac death.
