Abstract | 「要旨」 心房中隔欠損症 (33症例 : 年齢46土12歳) を用い, 心RIアンジオグラフィのファースト・パス法により右室駆出分画 (RVEF) を求め, 心カテーテル法による平均肺動脈圧 (mPA) と比較した. 心房中隔欠損症では, 僧帽弁疾患および閉塞性肺疾患とは異なり, RVEFはmPAを反映していなかった (相関係数 : r = -0.42) . しかし肺体血流量比 (Qp/Qs) が2.0以下の症例では, 相関係数 r = -0.71 で RVEF は mPAを良く反映していた. 心房中隔欠損症の RVEF の低下には, mPA と Qp/Qs の両者の関与が示唆された. 「I. はじめに」 右心機能の評価として右室駆出分画の測定は右心室の負荷を表す指標の一つである. しかし, 左心室と違ってその形態が複雑なことにより, 心血管造影法・超音波法では右室容積の測定は困難で未だ確立された方法はない. |

Abstract | [Summary] Right ventricular ejection fraction (RVEF) assessed by cardiac radionuclide angiography has been applied to evaluate right ventricular function such as ischemic, valvular and congenital heart disease. Using this modality, previous reports also suggest that there is good correlation between RVEF and mean pulmonary arterial pressure (mPA) from catheterization findings in mitral valvular disease and chronic obstructive lung disease. In this study, cardiac RI angiography were performed on 33 adult patients with atrial septal defect (ASD) . RVEF is not so good correlation (r = -0.42) with mPA, but in cases within pulmonary to systemic ratio (Qp/Qs) less than 2.0 limits, there is good correlation between RVEF and mPA (n = 9, r = -0.71) . As a conclusion, in ASD, both afterload assessed by mPA and preload assessed by Qp/Qs decrease RVEF. |
