We report a case of sudden onset of angina 11 years after implantation of a No. 8 Model 2300 Starr-Edwards cloth-covered aortic valve prosthesis for aortic stenosis and insufficiency. At operation the cloth covering one strut of the metal cage was tenuously attached to the ring of the prosthesis, with its free end completely occluding the right coronary artery ostium. The valve was replaced and the obstructing foreign body removed, re-establishing the patency of the right coronary artery.
scite is a Brooklyn-based startup 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 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.
