The angle through which an upright subject must be rotated in the left anterior oblique position in order to separate the left lower cardiac border (left ventricle) from the vertebral column is the angle of clearance of the left ventricle. Wilson1first used this term and determined this angle by means of a rotating turntable. In 119 normal children ranging in age from five to 15 years, she...Bibliography1.
