| Abstract | 「要旨」心室中部肥大型心筋症(MVO)は稀な病型であるため, 核医学検査による診断および病態解析の意義は明らかでない. そこでわれわれの経験した心尖部心室瘤を合併したMVOの一例にタリウム心筋シンチグラムとRIアンギオグラフィを施行し, その有用性を検討した. 前者により心室中部肥大と心筋障害の程度の把握が可能であり, 後者により左室内腔の砂時計様変形と位相遅延を伴った心尖部心室瘤の診断が容易であった. さらに心尖部の容量曲線を検討すると通常の心筋梗塞後の心室瘤と異なり, 心室中部閉塞機転に基づくasynchronyの存在が心室瘤形成上重要な役割を演じていることが示唆された. 核医学的手法はMVOの診断上有用であり, さらに病態解析上も重要な示唆を与える検査法と考えられた. 「I. はじめに」心室中部肥大型心筋症(MVO)は, 1976年Falicovが肥大型閉塞性心筋症の一亜型として最初に報告し, X線左室造影のhour-glass appearanceと, 左室中部で生じる心内圧較差を特徴として記載している. |

| Abstract | [Summary] 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. |
