Imaging findings
Black blood MRI showed significant right heart enlargement and enlarged main pulmonary artery, with preferential enlargement of the left pulmonary artery. Cine MRI demonstrated a jet of accelerated flow going upward into the RVOT and main PA (stenosis) and another jet going downward (regurgitation). The pulmonic valve itself was dysmorphic, appearing bicuspid or with an atretic leaflet.
Key takeaways
This case showed classic findings of combined pulmonic stenosis and regurgitation, likely congenital given the patient's young age (30s). The preferential enlargement of the left pulmonary artery is a characteristic finding in pulmonic stenosis, often caused by the jet hitting the left PA. The dysmorphic valve confirmed the structural abnormality.
