• (1) We performed right heart catheterization and direct left atrial puncture. The calculated blood volume by dye dilution method was divided into 3 parts; i.e. the blood volume from the pulmonary artery to the brachial artery, from the left atrium to the brachial artery and from the pulmonary artery to the left atrium.(2) The true lung blood volume, true left atrial blood volume and left ventricular-aortic blood volume were calculated by using above mentioned method of measurement. By this method, direct determination of the blood volume in the lung and left atrium became possible.(3) The true lung blood volume does not reveal marked increase in acquired valvular diseases, and no marked difference in it was noticed among each type of valvular lesions.(4) There was a relationship between the left atrial blood volume and the degree of dilatation of the left atrium determined by the X-ray findings.(5) The comparison of the left ventricularaortic blood volume and electro-cardiographic findings confirmed the fact that an increased load of left ventricle results in a increased blood volume.
