Infective endocarditis in intravenous drug users is uncommon in left-sided native valves. Adding to the rarity, in this case, is endocarditis from Candida species complicated by ST-elevation myocardial infarction. Embolic myocardial infarction has worse outcomes as compared to other etiologies, and the management of septic embolic myocardial infarction is rather challenging. The management of embolic myocardial infarction from Candida endocarditis vegetation includes antifungal therapy. The use of anti-thrombotic therapy and anticoagulation carries a significant risk of fatal neurologic complications and has been controversial, with limited observational data available. Among percutaneous coronary interventions, balloon angioplasty and stenting have been associated with multiple complications while aspiration embolectomy appears to be a safer option. Surgical management is considered if medical and interventional therapies fail or if there is an indication for valve replacement.

Methicillin-resistant staphylococcus aureus (MRSA) pericarditis is a rare life-threatening infection. A 46-year-old female with hypertension, acquired immunodeficiency syndrome (AIDS) and recurrent neck abscesses, presented with a neck abscess and sepsis. Bloody purulent drainage from the abscess was found and antibiotics were started. Drainage was positive for MRSA. Four days after, course was complicated by acute pericarditis and pericardial tamponade; pericardial fluid was drained and was positive for MRSA. Vancomycin was continued, and aspirin and colchicine were started. Two days later, there was a recurrent pericardial fluid collection with loculation. Surgery was thought to be dangerous in the setting of CD4 count of 12. She was managed conservatively thereafter, with vancomycin, aspirin and colchicine, and was successfully discharged from the hospital.
