title: A case of intra-cardiac right-sided mural infective endocarditis associated with ventricular septal defect despite prophylactic antibiotics: a case report.
abstract: Bacterial endocarditis secondary to jet lesions from congenital heart disease is not uncommon, and has been reported on numerous occasions in the literature. These cases usually involve one or more cardiac valves. Our case is that of isolated intracardiac right-sided mural infective endocarditis associated with ventricular septal defect. Importantly, this patient had preceding dental work treated with antibiotic prophylaxis. This case highlights bacteraemia secondary to dental instrumentation versus routine oral hygiene. His presentation was predominantly that of respiratory symptoms and sepsis, and he was culture negative throughout his admission. The lesion was detailed on echocardiography and transoesophageal echocardiography, and treated conservatively. He has subsequently been referred for VSD closure.
