Mycotic Pseudoaneurysms of the Coronary Arteries.

Background: Mycotic coronary artery aneurysms are rare and are often fatal without early recognition and prompt surgical management.

Methods: We present a case of mycotic pseudoaneurysm of the left main coronary artery (LMCA) after disseminated methicillin-sensitive Staphylococcus aureus (MSSA) bacteraemia. A review of the literature in regards to the surgical management of coronary artery mycotic pseudoaneurysms was conducted.

Results: There were 26 reported cases of surgical management of coronary artery mycotic pseudoaneurysms. Coronary artery bypass surgery (CABG) and excision was the most common management (73.1% of cases reviewed).

Conclusions: This case highlights the difficultly in diagnosing mycotic coronary artery pseudoaneurysms.
