31P MRS can noninvasively
reflect the in vivo energy metabolism without using ionizing radiation. It
has been widely applied in the clinical studies of cardiac energetics under
different pathophysiological conditions. The aim of the present study was to evaluate
the myocardial energetics in 30 patients with moderate or severe degenerative
mitral regurgitation (DMR) using 31P MRS.
