Imaging findings
The imaging demonstrates massively dilated pulmonary arteries. A key teaching point is the clear visualization of pulmonary artery atherosclerosis, with calcified atheromatous plaques visible in profile and in patches within these severely dilated pulmonary arteries. The patient also has an atrial septal occluder device in place.
Key takeaways
Severe pulmonary hypertension, regardless of etiology, can lead to marked dilation of the pulmonary arteries. Chronic severe hypertension promotes the development of pulmonary artery atherosclerosis, characterized by calcified atheromatous plaques within the pulmonary artery walls, which are a direct correlate of the severity and chronicity of the hypertension.
