Midventricular hypertrophy (MVO) is a rare and complicated myocardial disease. Its pathophysiology and prognosis remain unknown, and few nuclear cardiological findings for MVO were reported. On a 44-year old man with MVO, thallium-201 (Tl) myocardial scintigraphy and gated blood pool scintigraphy (GPS) were performed to evaluate their usefulness. GPS revealed a characteristic hour-glass deformity of the left ventricular cavity, apical aneurysm and asynchrony due to obliteration of the midventricle. Anteroseptal hypertrophy in midventricle and myocardial damage in apico-inferior region were detected by Tl. Thus, nuclear cardiological studies are proved to be useful and essential in not only diagnosis but also evaluating pathophysiology and observing natural history noninvasively.
心室中部肥厚（MVO）是一种罕见且复杂的心肌病。其病理生理学和预后尚不清楚，关于MVO的核心脏病学研究结果报道较少。对一名患有MVO的44岁男性进行了铊-201（Tl）心肌闪烁显像和门控心血池显像（GPS），以评估其效用。GPS显示左心室腔呈特征性的沙漏样变形、心尖部室壁瘤以及由于心室中部闭塞导致的不同步。Tl检测到心室中部前间隔肥厚以及心尖下区域的心肌损伤。因此，核心脏病学研究不仅在诊断中，而且在无创评估病理生理学和观察自然病史方面都被证明是有用且必要的。
