there was a direct proportional relationship between the pulmonary valve annulus diameter and the cube root of the right ventricular volume ( r = 0.952 ) , as well as between sv and cross-sections of the right pulmonary artery ( rpac ; r = 0.916 ) , left pulmonary artery ( lpac ; r = 0.878 ) and descending thoracic aorta ( r = 0.962 ) .
