| Abstract | 「要旨」僧帽弁疾患33例を対象に99mTc標識赤血球による平衡時マルチゲート心プールシンチグラムを行い, 安静時と運動負荷時の右室駆出分画(RVEF)を算出するとともに, これらの値と心カテーテル法により求めた平均肺動脈圧(mPAP)との関係について検討した. 運動負荷時のRVEFは安静時よりも有意に低下した. 安静時のRVEFとmPAPとの間に有意な相関はみられなかったが, 運動負荷時のRVEFとmPAPとの間, 安静時に対する運動負荷時のRVEFの変化率(ΔRVEF)とmPAPとの間にはいずれも有意な負の相関が認められた. 運動負荷時の右室の駆出能は右室後負荷に強く影響されることが明らかとなるとともに, 平衡時心プールシンチグラムから算出したRVEFの値から平均肺動脈圧を推定することも可能であり, 本法は僧帽弁疾患の右室後負荷の評価において有用な検査法と考えられる. |

| Abstract | [Summary] Right ventricular function at rest and during exercise was studied in 33 patients with mitral valve disease by equilibrium gated radionuclide angiography using 99mTc in vivo labeled red blood cells. Radionuclide measurements of right ventricular ejection fraction (RVEF) were correlated with mean pulmonary arterial pressure (mPAP). RVEF decreased significantly with exercise. There was no significant correlation between RVEF at rest and mPAP. However, mPAP showed significant negative correlation with RVEF during exercise and with the changes of RVEF from rest to exercise. It is concluded that RVEF during exercise in mitral valve disease is affected by right ventricular afterload, and the measurements of RVEF at rest and during exercise by equilibrium gated radionuclide angiography is useful to assess right ventricular afterload. |
