ST-elevation myocardial infarction from septic embolism secondary to prosthetic aortic valve endocarditis: a case report.

BACKGROUND

ST-elevation myocardial infarction (STEMI) is a cardiac emergency that requires prompt diagnosis and treatment. We describe a challenging and complex case of managing acute STEMI in a patient with severe anaemia, deranged clotting profile, and infective prodrome.

CASE SUMMARY

A 54-year-old Caucasian gentleman was referred by his general practitioner as an emergency after presenting with acute onset of chest pain. His electrocardiogram revealed anterior ST elevation. His past medical history includes a mechanical aortic valve, requiring anticoagulation, and a recent gastrointestinal bleed secondary to type C gastritis. His initial presentation was further complicated by severe anaemia, deranged clotting profile, and elevated infective markers. He required a prompt transfer to the catheterization laboratory to assess and stabilize the situation. We discuss the emerging challenges during treatment, particularly as the diagnosis of septic embolism from infective prosthetic valve endocarditis was unfolding, requiring urgent cardiac surgery.

DISCUSSION

Acute coronary vessel closure leading to STEMI from septic embolism secondary to prosthetic aortic valve endocarditis is very rare. It is essential to consider the whole picture of the presentation for timely diagnosis and tailored treatment.
