| Abstract | 「要旨」不整脈源性右室異形成症(ARVD)7例について心プールシンチグラフィを施行し, 両心室における駆出分画に加え, 位相振幅解析により局所壁運動異常の分析を行った. 対照群14例に比し, ARVD群では有意なRVEFの低下(38±10%)を認めた. 位相解析イメージでは, 右室流出路に位相の著明に遅延した部位が認められ, 位相ヒストグラムで位相値標準偏差の増大を認めた. また, 位相イメージにより著明な遅延を示した部位は, 心エコー図, 右室造影などの検査により病変の示唆された部位に一致し, 電気生理学的検査にても同部位が心室頻拍のfocusと考えられた. このように心プールシンチグラフィは, 非観血的に右室の形態, 機能異常を評価しうるため, ARVDの診断において有用である. |

| Abstract | We evaluated right and left ventricular function in 7 cases of arrhythmogenic right ventricular dysplasia (ARVD) by radionuclide cardioangiography. The right and left ventricular ejection fraction (RVEF, LVEF) were calculated. And, phase and amplitude images were also obtained from gated blood pool scan. Mean RVEF was 38+-10% in patients with ARVD and 56+-5% in control subjects (p<0.001), respectively. In patients with ARVD, the phase image indicated the delay in the inferior wall of right ventricular inflow tract. Average of the standard deviation of the phase histogram was 31 degrees in patients with ARVD and 5 degrees in control subjects (p<0.001). The delayed site in the phase image was correlated to the site, in which was suggested the lesion by two-dimensional echocardiography and right ventriculography. It was also correlated to the site, in which was suggested the focus of ventricular tachycardia by electrophysiological examination. In conclusion, radionuclide method provides useful information in the diagnosis of patients with ARVD. |
