A 17 year old girl with a congenital right coronary artery to coronary sinus fistula presented with recurrent septic pulmonary embolism secondary to tricuspid valve endocarditis. The diagnosis was made on the basis of echocardiography and cardiac angiography.
A 10-year-old girl with mild aortic regurgitation presented with cerebral infarction. Two-dimensional echocardiography showed vegetations on the septal wall of the left ventricular outflow tract without involvement of the aortic valve itself. After successful antibiotic treatment the patient developed an intra-cranial haemorrhage due to rupture of a large intracranial mycotic aneurysm. Consent for surgical treatment of the mycotic aneurysm was not obtained. Twelve months later repeat angiography showed that the aneurysm had undergone spontaneous obliteration.
A 6-year-old boy presented to a university hospital in Malaysia with infective endocarditis complicating cyanotic congenital heart disease. Blood cultures showed a gram-positive, aerobic, coryneform-like bacillus identified by the hospital laboratory as Corynebacterium xerosis, but a reference laboratory identified the organism as a toxigenic strain of Corynebacterium diphtheriae. The two laboratories concurred on all biochemical test results except for sucrose fermentation.
We present an interesting case of late-onset intracranial bleeding (ICB) as a complication of Streptococcus gordonii causing infective endocarditis. A previously healthy young woman was diagnosed with infective endocarditis. While she was already on treatment for 2 weeks, she had developed seizures with a localising neurological sign. An urgent non-contrasted CT brain showed massive left frontoparietal intraparenchymal bleeding. Although CT angiogram showed no evidence of active bleeding or contrast blush, massive ICB secondary to vascular complication of infective endocarditis was very likely. An urgent decompressive craniectomy with clot evacuation was done immediately to release the mass effect. She completed total 6 weeks of antibiotics and had postoperative uneventful hospital stay despite having a permanent global aphasia as a sequel of the ICB.
