[A case of dilated cardiomyopathy with early back-diffusion of 123I-BMIPP].
A 28-year-old woman was pointed out cardiomegaly and diffuse hypokinesis of left ventricle by ultrasonography in community hospital. Coronary angiography showed normal coronary artery and, left ventriculography revealed diffuse hypokinesis (LVEF 40%). She was diagnosed idiopathic dilated cardiomyopathy by myocardial biopsy and other clinical information. Myocardial scintigraphy with 201Tl. revealed dilatation of left ventricle and diffuse inhomogeneous accumulation of 201 Tl. Dynamic 123I-BMIPP SPECT image 2 minutes after injection showed BMIPP accumulation in all segment, though, static image 15 minutes after injection indicated reduced BMIPP accumulation. These findings suggested existence of the early back-diffusion in inferior segment. Early back-diffusion of BMIPP may become a marker of abnormal fatty acid metabolism in patient with dilated cardiomyopathy.
