  • Look Inside

Chest roentgenograms were taken in 30 patients (pt) with atrial septal defect (ASD, mean 37 y/o), 54 pt with primary pulmonary hypertension (PPH 29 y/o) and 100 normals (31 y/o) as control. The method used consisted of measurement of the following 5 items on posteroanterior chest roentgenograms ob-tained by routine method. (1) Ao : width of the aortic knob from the midline, (2) DPA : width of the pulmonary artery from the midline, (3) PL : the point of union of the external border of the upper lobe artery with the pars interlobaris was identified as point L and the sum of horizontal distance of the right and left L to the midline was defined as PL, (4) dPA : width of the descending branch of the right pulmonary artery (PA), (5) maximum transverse dia-meter of the heart. (1) and (2) was divided by a half thoracic diameter (T/2) and (3) and (5) by (T). Cor-relation of these items and pulmonary hemodynamics was also examined.

In Ao/(T/ 2), ASD showed significantly smaller value compared with other groups. All other para-meters took greater values in disease groups. DPA /(T/2) and PL/T correlated positively with PA pressure in both pt groups and in addition dPA in ASD. Pt with dPA≧30mm revealed mean PA pressure 30mmHg.

We conclude that chest roentgenogram can afford useful information for the diagnosis and noninvasive detection of pulmonary hemodynamics.
