Key result
A mobile papillary fibroelastoma of the aortic valve caused acute myocardial infarction by obstructing the coronary ostium, and symptoms resolved after surgical resection.
This case highlights that a mobile papillary fibroelastoma of the aortic valve can obstruct the coronary ostium, causing acute myocardial infarction, and can be successfully treated with surgical resection.
Papillary fibroelastoma warrants consideration in AMI with normal coronaries; single case leaves open diagnostic algorithm changes.
We present a case of a 75-year-old woman with typical myocardial infarction, however coronary angiogram was negative. Echocardiography identified the rare cause of chest pain, as a mobile mass of aortic valve was found to obstruct the coronary ostium. histopathology revealed a papillary fibroelastoma (PFE). Chest pain was relieved after surgical resection of the mass.
