Abstract
The relation between flow velocity and the pressure decrease is evalua ted in Blalock-Taussig shunts used in congenital heart surgery and is related to the flow conditions and geometries of the shunts studied. T he authors propose that the flow conditions within the shunt as well a s shunt dimensions need to be taken into account when using Doppler ve locimetry to predict pressure drops across these shunts.
