Waterston shunt

Dr Jeremy Jones and A.Prof Frank Gaillard et al.

A Waterston shunt is a form of palliative surgery performed in patients with tetralogy of Fallot prior to the ability to repair the defect. It consists of a shunt formed between the ascending aorta and the right pulmonary artery.

This does not relieve the right ventricular outflow obstruction, but simply improves pulmonary blood flow and improves cyanosis.

A significant demerit of this shunt is that it is not a controlled shunt, if anastomosis is too large it may lead to pulmonary vascular disease due to excessive blood flow to the lung.

Congenital heart disease

There is more than one way to present the variety of congenital heart diseases. Whichever way they are categorised, it is helpful to have a working understanding of normal and fetal circulation, as well as an understanding of the segmental approach to imaging in congenital heart disease.
