Abstract :
The aim of the study was to determine whether pulmonary valve (PV) haemodynamics are affected by congenital aortic valve disease (CAVD). A large amount of retrograde to antegrade flow was seen in patients with a dilated MPA, which was also shown in the 3D velocity profiles. This would appear to suggest that PV haemodynamics downstream of the valve can be affected by CAVD. However, the normal cardiac index (CI), systolic and diastolic flow suggests that the PV is not compromised in patients with CAVD
