| Abstract | 著者らは, (1)冠動脈再建術中の僧帽弁逆流(MR)の頻度と重症度, (2)MRの重症度の変化と左室機能, すなわち, 左室拡張末期面積, 収縮末期面積, 面積駆出率, 僧帽弁輪径, そして. 局所壁異常運動との関連について研究を行なった. 経食道心エコー・カラードプラ法により20例すべてに麻酔導入後MRを検出した. 15例はtrivial(生理的) MR, そして5例のみmild(軽度) MRであった. しかしながら, 体外循環後では8例のみがtrivialであり, 11例がmild MR, 1例がmoderate(中程度) MRであった. MR体外循環20例中9例(45%)で増加した. これら9例の患者では, (1)MRが増悪しなかった症例と比較して, 左室の拡張, 面積駆出率の低値を認め, (2)体外循環後の僧帽弁輪の拡大, (3)体外循環前後とも, 局所壁運動異常を認める頻度が高くかつ重篤な局所壁運動異常の存在が指摘された. |

| Abstract | 「Summary」We studied 1) incidence and degree of mitral regurgitation (MR) during coronary artery bypass surgery and 2) relationship between change in degree of MR and ventricular function, i.e., left ventricular end-diastolic and end-systolic area, area ejection fraction, diameter of mitral annulus, and regional wall motion abnormality (RWMA). Transesophageal color Doppler imaging detected MR in all 20 patients after induction of anesthesia ; 15 patients showed trivial MR, and only 5 had mild MR. However, 8 patients showed trivial, 11 mild, and 1 monderate MR following cardiopulmonary bypass (CPB). MR increased following CPB in 9 of 20 patients (45%). These 9 patients showed 1) an enlarged left ventricle and low area ejection fraction even before CPB compared with others without the increase in MR, 2) mitral annular dilatation in the post-CPB, and 3) more frequent and severe RWMA in both pre- and post-CPB. |
