Cardiovascular magnetic resonance in a pregnant patient with absent pulmonary valve syndrome.

We present a 22 year old Moroccan woman with chronic severe pulmonary regurgitation, who becomes symptomatic in her fourth month of pregnancy. Cardiovascular magnetic resonance, during pregnancy, revealed a large pulmonary aneurysm and turbulent blood flow in the pulmonary trunk with severe pulmonary regurgitation. After gestation, the branch pulmonary arteries were assessed with magnetic resonance angiography and the severely dilated pulmonary arterial trunk and valve were replaced by a pulmonary homograft. We briefly review this rare syndrome, the management of pulmonary regurgitation during pregnancy and the role of CMR during pregnancy.
