    Journal: Eur Heart J Case Rep; 2023 Nov; 7(11):ytad584. PubMed ID: 38025118.
    Abstract:
    BACKGROUND: Purulent pericarditis is rare in the modern era of antibiotics. However, it is a rapidly progressive, life-threatening disease with complications, including cardiac tamponade and left ventricular pseudoaneurysm. CASE SUMMARY: A 44-year-old female was admitted with a pontine haemorrhage. On the 25th day of admission, she developed a fever along with chest pain and dyspnoea. Transthoracic echocardiography and computed tomography revealed a large pericardial effusion, leading to the diagnosis of cardiac tamponade. Pericardiocentesis was performed, resulting in the drainage of 750 mL of blood-stained fluid. Blood and pericardial fluid cultures were positive for Staphylococcus aureus; therefore, ceftriaxone was administered. On the 49th day, she became febrile again, and computed tomography showed increased pericardial effusion. Transthoracic echocardiography confirmed the large pericardial effusion and revealed a pseudoaneurysm on the inferior of the left ventricular wall, with blood flowing from the pseudoaneurysm into the pericardial space. Urgent surgical intervention was performed to repair a myocardial defect as a left ventricular pseudoaneurysm had ruptured in the pericardium. The patient recovered and was transferred to another hospital for rehabilitation after 108 days of hospitalization. DISCUSSION: Purulent pericarditis can be a lethal complication; therefore, careful follow-up and strict adherence to therapeutic strategies, including the use of imaging technologies such as echocardiography, are important.
