Pott shunt

A Pott 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 descending thoracic aorta and the left pulmonary artery.

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