Displacement of left ventricle in atrial septal defect.
Catheterization and biplane cineangiography were performed in 28 patients with atrial septal defect. The left and right ventricular volume in end-systole and end-diastole were estimated with a computed method. The relation between the left and right stroke volume ratio and the posterior displacement of the left ventricle was analysed. A statistically highly significant positive correlation between the angle of the long axis of the left ventricle and the shunt was established.
