A diabetic patient was admitted to our hospital for infective endocarditis with acute purulent pericarditis and diabetic ketoacidosis. Echocardiography revealed attachment of vegetation to the chordae tendineae in the left ventricle and pericaridial effusion. The vegetation was enlarged and pendulated for a few days despite maximal antimicrobial therapy. Surgical resection was desirable to decrease the risk of embolic complications and cardiovascular collapse. We could not open the heart because of accumulation of purulent pericardial fluid, and right renal infarction was complicated. We believe that the immunocompromised and hypercoagulable state due to diabetes caused these conditions.

Right-sided endocarditis is predominantly seen in patients with a history of intravenous drug abuse. However, it is well shown in the literature to be associated with patients containing foreign bodies such as pacemakers, central venous lines, and in those with congenital heart disease. In patients with pacemaker leads and in those with automatic implantable cardioverter defibrillators (AICDs), it is important to suspect foreign body infection when there are signs and indications of bacteremia. When these leads become infected, they can spread the infection to the tricuspid valve resulting in vegetations. The proper management is removal of the infected lead and foreign body along with a prolonged course of antibiotics. However, it is unusual and a relatively rare entity to see foreign body infection resulting from a wound ulcer resulting in not only endocarditis but also abscess formation on the tricuspid valve. Here we report a case of a 60-year-old male with recent AICD placement presenting as diabetic ketoacidosis due to tricuspid abscess formation as a result of a foot ulcer.

BACKGROUND In the modern antibiotic era, Streptococcus agalactiae infection of the endocardium and pericardial space is a rare occurrence. However, once the disease spreads it can lead to life-threatening illness despite advances in diagnostic and treatment modalities, partly because the symptoms and signs associated with pericarditis are frequently missing, and due to the rarity of the disease, diagnosis is often overlooked. We report an extremely rare case of purulent pericarditis caused by Streptococcus agalactiae. CASE REPORT A 65-year-old diabetic woman presented with generalized weakness, high-grade fever, and altered mental status. There were no signs or symptoms suggestive of cardiac tamponade on presentation. A computerized tomography (CT) scan of the chest showed a small pericardial effusion. She was managed for diabetic ketoacidosis and sepsis. An electrocardiogram was significant for new-onset atrial fibrillation. Her clinical status deteriorated rapidly as she developed acute hypoxic respiratory failure and shock. A bedside echocardiogram showed large pericardial effusion around the right ventricle and right ventricular diastolic collapse. She developed cardiac arrest, and during resuscitation bedside pericardiocentesis was done with drainage of 15 cc of serosanguineous fluid. However, the patient could not be revived. Subsequently, blood cultures grew Streptococcus agalactiae a day after she died. On autopsy, she was found to have findings of infective endocarditis and purulent pericarditis. CONCLUSIONS A high index of clinical suspicion is crucial when acute pericarditis is suspected, for early diagnosis and for timely initiation of appropriate therapy with antibiotics and aggressive pericardial drainage to prevent fatal outcome.
