**8. Summary**

Transcatheter RVOT stenting is increasingly preferred over other palliative procedures as aorto-pulmonary shunts have a very unpredictable course post-operatively, especially neonatal BT shunts. The risks of shunt thrombosis or pulmonary over circulation can influence the post-operative recovery, shunt leads to disruption and distortion of the pulmonary arteries which can significantly impact the definitive repair at a later date. RVOT stenting establishes a more physiological flow to pulmonary arteries and encourages equal growth of small pulmonary arteries providing a better surgical substrate for subsequent repair.
