Acute myocardial infarction caused by coronary embolization of a papillary fibroelastoma of the thoracic ascending aorta.
Papillary fibroelastomas (PFE) are benign endocardial masses and generally originate from the cardiac valves, while PFE arising from the ascending thoracic aorta are an uncommon clinical finding. We report the case of a 78-year-old female who presented to the emergency department with an acute ST segment elevation myocardial infarction. Urgent coronary angiography showed no significant coronary artery obstructive disease but left ventriculography revealed the presence of a highly mobile mass located in the proximal portion of the ascending thoracic aorta. We postulated that the clinical symptoms were caused by embolization from the aortic mass and surgical excision of the peduncle was performed. Histopathological examination revealed a PFE with thrombotic material. Nowadays, surgical excision of PFE remains, the treatment of choice for symptomatic patients with excellent short- and long-term results but recurrence of PFE following surgical excision has not been reported.
