Formation of ventricular aneurysm after endocarditis in a child with methicillin-resistant Staphylococcus aureus (MRSA) bacteremia

Pancarditis: an unusual complication of a group B streptococcal infection

Pancarditis is a rare condition with a poor prognosis combining endocarditis, myocarditis with abscess formation, and purulent pericarditis. Diagnosis is often delayed and the clinical signs are predominantly those of the embolic complications. Literature is scarce. We present a unique and rare case of pancarditis, complicating a Streptococcal B infection in an immunocompetent, healthy, 54 year-old woman. The evolution was favourable under medical therapy alone and thanks to multimodality cardiac imaging diagnosis and follow-up.

Bacterial pancarditis with myocardial abscess: successful surgical intervention in a 14-month-old boy

A 14-month-old boy with a structurally normal heart presented with signs of cardiac tamponade caused by purulent pericarditis. During his hospital stay, mitral and tricuspid valve endocarditis developed, and a ventricular septal abscess expanded despite appropriate, prolonged antibiotic therapy for methicillin-resistant Staphylococcus aureus. The day before scheduled surgical correction, the abscess ruptured, creating a septal aneurysm. Surgical intervention resulted in an excellent outcome. Throughout the patient's 67-day hospitalization, the use of echocardiography was crucial in monitoring and diagnosis. In addition to reporting this case, we discuss our diagnostic and treatment considerations. To our knowledge, this is only the 4th report of S. aureus bacterial pancarditis with myocardial abscess.

Post-infective pericarditis left ventricular pseudoaneurysm: a case report and review of literature

Post-infective pseudoaneurysm of the left ventricle in children is very rare, with only five cases reported in English medical literature so far. Patients usually have a short history of infection by Staphylococcus aureus. Timely surgical intervention has generally a good outcome. We present a case of post-infectious pseudoaneurysm in a 2-year-old girl with a review of literature.

Unusual left ventricular pseudoaneurysm in a child after disseminated bacterial infection

Left ventricular pseudoaneurysms are rare in children. A six-year-old boy developed left ventricular pseudoaneurysm despite successful control of sepsis. The pseudoaneurysm was diagnosed by two-dimensional echocardiography and detailed by computed tomography. The child underwent successful surgical correction with partial excision and plication of the aneurysmal sac.

Update on Epidemiology and Treatment of MRSA Infections in Children

In 2000-10 the epidemiology of pediatric MRSA infections in the United States was transformed with an epidemic of CA-MRSA infections. We review the epidemiology of MRSA in the community and in the health care setting, including intensive care units, among infants and CF patients, and in households as well as the impact that the CA-MRSA epidemic has had on hospitalization with MRSA infections. Risk factors for carriage, transmission, and initial and recurrent infection with MRSA are discussed. New studies on the treatment of pediatric MRSA infections and on the efficacy of MRSA decolonization are reviewed.
