Abstract
心疾患を有する患者では,その循環動態は種々の因子により容易に変化するものであり,一回の検査のみで決して正確にその患者の動態を表わしているとはいいがたい.この点コンピューターを用いたRI angio-cardiography(以下RCGと略す)は被曝線量も少く,生理的状態を損うことなく繰返し検査を行うことが出来る非観血的方法であり,心疾患者の術前術後の変化,治療経過観察に極めて有用である.従って,僧帽弁疾患におけるRCGによる右室,左室peak to peak time C(2)/C(1)比の解折は,上述の点後於て重要な臨床情報を提供すると考えられる.今回は僧帽弁疾患を中心としてこれらの点について若干の検討を試みた.

This report represents an extension of our use of a Scintillation (Anger) camera with computer processing (Toshiba DAP 5000-2) of data for evaluation of mitral valve disease (11 cases). For these studies we have administered 10 mCi of (99m)Tc intravenously and have followed its passage through the heart and lung using techniques for data acquisition: a 35 mm camera, a video tape system for data storage and replay for computer analysis using a DAP 5000-2. RI dilution curves recorded on the right ventricle, the left lung and the left ventricle were analyzed to obtain following parameters, namely interventricular peak to peak time, C(2)/C(1) ratio of each dilution curves. These data showed following: 1) Interventricular peak to peak time normal group (12 cases): 6.40 ± 1.18 seconds mitral valve disease (11 cases): 11.34 ± 3.69 seconds 2) a) C(2)/C(1) ratio of the right ventricle normal group: 0.45 ± 0.08 seconds mitral valve disease: 0.58 ± 0.17 seconds b) C(2)/C(1) ratio of the left ventricle normal group: 0.38 ± 0.09 seconds mitral valve disease: 0.49 ± 0.11 seconds c) C(2)/C(1) ratio of the left lung normal group: 0.45 ± 0.08 seconds mitral valve disease: 0.50 ± 0.12 seconds
