[Two patients with hypertrophic cardiomyopathy showing regionally increased washout of 123I-MIBG from the thick myocardium].
123I-MIBG scintigraphy was performed in two patients with hypertrophic cardiomyopathy. These patients showed marked asymmetrical wall thickening in the left ventricle. The findings of 123I-MIBG scintigraphy in the thickened wall were regional increased washout and defect in the delayed images with preserved 201Tl uptake. This mismatched finding, which is correlated with ventricular tachycardia, gives useful information for follow-up of the patients with HCM.
