Utility of Doppler Echocardiography in the Evaluation of Aortic Homograft Valved Conduit Function in Children: Need for Segmental Conduit Interrogation

To assess the utility of Doppler echocardiography in evaluation of aortic homograft valved conduit function, 10 consecutive pediatric patients had Doppler examination of aortic homograft valved conduits associated with follow‐up cardiac catheterization. General correlation was found between the Doppler‐derived peak systolic pressure gradient across the aortic homograft valved conduit and cardiac catheterization (r = 0.65, P < 0.05, SEE =...
