| Abstract | <要旨> 心RIアンジオグラフィを用いて右室における局所壁運動の観察方法を開発し, 各種心疾患に応用した. 方法はRAO30°, LAO40°にて, それぞれfirst pass, multi-gate法を併用し, 右室を(1)inflow, (2)sinus portion, (3)out flow, (4)septal, (5)lateralの5部位に, かつ収縮様式はnormalからdyskinesisに到る4段階として右室局所壁運動の評価を行なった. 本法は, 右心(圧, 容量)負荷疾患や心筋梗塞症例にて右室梗塞合併症例にて威力を発揮した. とりわけ, 右室梗塞症例では, 心エコー図, 右室造影所見と対比しても良好な結果が得られた. すなわち, 右室梗塞症例における右室の拡大, 収縮様式の低下を明瞭に捉えることができた. 今後, 心RIアンジオグラフィは, 非観血的に両心室における形態, 機能を評価する簡便な方法として有用な手段となると考えられる. |

| Abstract | [Summary] Radionuclide cardioangiography is a useful method to evaluate the left ventricular wall motion in various heart diseases. It has been also attempted to assess the right ventricular wall motion simultaneously by radionuclide method. In this tudy, using the combination of first-pass (RAO 30°)and multi-gate(LAO 40°)method, the site of right vetricle was classified in five. (1 inflow, 2 sinus, 3 outflow, 4 septal, 5 lateral)and the degree of wall motion was classified in four stages(dyskinesis, akinesis, hypokinesis, normal)according to the AHA committee report. These methods were applied clinically to forty-eight patients with various heart diseases. In the cases with right ventricular pressure or volume overload such as COLD, pulmonary infarction, the right ventricle was dilated and the wall motion was reduced in all portions. Especially, in the cases with right ventricular infarction, the right ventricular wall motion was reduced in the infarcted area. The findings of radiocuclide method were in good agreements with those of contrast right ventriculography or echocardiography. In conclusion, radionuclide cardioangiography is a useful and noninvasive method to assess not only the left but also the right ventricular wall motion. |
