| Abstract | 「要旨」下後壁梗塞に合併した右室梗塞症例11を対象として心RIアンジオグラフィ, 心筋シンチグラフィなどの核医学的方法を用いて検討した. この結果, 右室梗塞症例にて以下の特徴ある所見が得られた. 心RIアンジオグラフィでは, 右室駆出分画の低下(平均36.5%)および右室1〜5segmentにおける局所壁運動の低下を認めた. また, 右室腔の拡大した症例にて三尖弁閉鎖不全の合併を認めた. 心筋シンチグラフィでは後下壁に, とくに後壁中隔部位にて欠損像を全症例に認めた. また, 心エコー図右室短軸面からの検索, 右室造影所見ともよく一致し, 本法が有用なことが認められた. 本法は非観血的であり, 繰返し施行できるので, 診断のみならず経過観察, 予後判定に有用である. 「I. 緒言」急性心筋梗塞症において, 梗塞部位, 拡がりを精度高く把握することは診断のみならず予後判定に重要である. |

| Abstract | [Summary]Eleven cases of right ventricular infarction were studied using radionuclide angiography and myocardial perfusion imaging. And then, the radionuclide diagnosis of right ventricular infarction was compared with the results of echocardiography and contrast right ventriculography. The characteristic findings of right ventricular infarction were as follows. 1. By radionuclide cardioangiography, the value of RVEF (mean RVEF 39%) were decreased significantly. And the right ventricular wall motion showed hypokinesis or akinesis in 5 segments of right ventricle. In all cases, infero-posterior segments of left ventricle showed akinesis according to the combination of infero-posterior myocardial infarction. 2. In myocardial perfusion imaging, in all cases, the perfusion defects were shown in the inferior, posterior, and postero-septal region of left ventricle and in coronary arteriograms. The main portion of right coronary artery had complete occulusion with the impairements of left ascending artery. 3. In comparison with echocardiography and contrast right ventriculography, radionuclide diagnosis of right ventricular infarction was good agreements with other findings. In conclusion, the noninvasive diagnosis of right ventricular infarction using radionuclide angio-cardiography and myocardial perfusion imaging were useful method in addition to the hot scan by 99mTc-phyrophosphate. |
