Novel use of intravascular lithotripsy for coral reef aorta: a case report.

Background: The coral reef aorta (CRA) is a rare disease of extreme calcification in the juxtarenal aorta. These heavily calcified exophytic plaques grow into the lumen and can cause significant stenoses, leading to visceral ischaemia, renovascular hypertension, and claudication. Surgery or percutaneous intervention with stenting carries a high risk of complications and mortality.
