Background
Coral reef aorta (CRA) is a rare condition characterized by atherosclerosis and overt calcification of the aorta leading to severe luminal stenosis of the vessel. Most patients present with hypertension and intermittent claudication at the time of diagnosis. Risk factors associated with this condition are essentially the same as those associated with atherosclerosis. However, no unique condition seems to predispose an individual to develop CRA.
Case summary
We describe the case of a patient known for rheumatoid arthritis (RA) treated with long-term systemic corticosteroids who presented with a shock of unknown aetiology and left ventricular ejection fraction of 10%. Conventional and computed tomography angiography showed a CRA with subtotal lesion of the aortic arch that led to cardiogenic shock.
Discussion
Even though the exact aetiology of her condition will remain uncertain, RA and extended use of corticosteroids likely played a role in the development of this severe form of CRA.
Complex and higher-risk indicated percutaneous coronary interventions at times require mechanical circulatory support, most often with Impella devices. The use of such devices traditionally required additional arterial access site(s), increasing risk of vascular complications. The Single-access for Hi-risk percutaneous coronary intervention (SHiP) technique was described to overcome this issue but was limited to the use of 7F guides. Larger 8F guides often provide incremental support and space compared to 7F guides, sometimes needed in complex procedures. We described a modified SHiP technique using an 8 Fr guide delivered sheathless using Rotaglide.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
