Infective endocarditis is associated with significant morbidity and mortality, with valvular destruction and congestive heart failure being more common in patients with echocardiographically discernible vegetations. The transoesophageal approach affords consistently high quality images with excellent structural resolution. Two-hundred and eighty-one patients with clinically suspected infective endocarditis were studied, to evaluate the prognostic value of ascertaining the site of vegetations. Among them were 118 patients with vegetations attached to the aortic or mitral valve. These patients were followed for a mean period of 14 months. Mitral valve vegetations were associated with a significantly higher incidence of embolic events than vegetations on aortic valves (25% vs 9.7%). The incidence of abscess formation was higher in aortic than in mitral valve endocarditis (6% vs 0%), as were the need for surgical intervention (11% vs 5.5%) and mortality (1.6% vs 0%) respectively). Bivalvular endocarditis was associated with an increased rate of complications: embolism (50%), abscess formation (15%), surgery (35%) and mortality (10%). By multivariate analysis, echocardiographically accessible risk factors for subsequent embolism were a vegetation size of more than 10 mm and mitral valve involvement. Risk factors associated with in-hospital fatality were embolism, a vegetation size of more than 10 mm, and Staphylococcus aureus infection. Our data suggest that the site influences both the rate and the type of complications. Precise echocardiographic visualization of vegetations helps to stratify patients into a high-risk sub-group, perhaps warranting early prophylactic surgical intervention. Transoesophageal echocardiography may play an important role in assessing the clinical outcome for these patients.

We report the case of a female neonate born at 40 weeks' gestation with no known risk factors. On postnatal day 27, she was transferred to the pediatric intensive care unit and intubated for cardiorespiratory failure; she was diagnosed with group B streptococcus infective endocarditis. Mitral valve vegetations did not improve with antibiotic therapy. Mitral valve surgery was performed on postnatal day 36. A mechanical mitral valve with short-segment polytetrafluoroethylene skirt was inserted into the supra-annular position; gentian violet was applied to the sewing ring and skirt. She was discharged from the hospital after 6 weeks with good cardiac function and normal sinus rhythm.
