A diagnosis of extremely thickened media of small pulmonary arteries was made when there were small pulmonary arteries in which the percentage wall thickness was 33% or greater, ie, when a + b ≥ 2c.

Case 8. Small pulmonary arteries with extremely thickened media from a patient who died 10 months after pulmonary artery banding. Each small artery has an extremely thickened media, and the luminal space is small, leaving room for only a few red blood cells (RBC) to pass through.

Case 10. The small pulmonary arteries show strongly hypertrophic media 4 months after operative repair. (RBC = red blood cells.)

Comparison of cardiac catheterization in the operative survivors versus deceased patients. Asterisks indicate late deaths. (PAMP = pulmonary arterial mean pressure; PASP = pulmonary arterial systolic pressure; PVR = pulmonary vascular resistance.)

6. Fig 5
The numerical percentage of small pulmonary arteries with percent wall thickness greater than 33% (percentage of thickened arteries) in 19 cases. Asterisks indicate cases in which pulmonary arterial pressure did not decrease.
