systolic and diastolic diameters of the right and left pulmonary arteries ( rpad , lpad ) , descending thoracic aorta ( dtad ) , right ventricular infundibulum ( rvid ) , and pulmonary and aortic valve roots at the proximal , commissural and distal levels were estimated from angiocardiograms in 24 infants , children , and adolescents without heart disease , and correlated with body surface area ( bsa ) , stroke volume ( sv ) , cardiac output ( co ) , and ventricular volumes .
