Human bites are an infrequent cause of emergency department visits and hospital admissions. There are rarely published cases of complicated infection, such as infective endocarditis. We present a rare case of a patient with acute infective endocarditis in a healthy native valve and purulent pericarditis from a human bite. A 40-year-old man with obesity suffered deep human bites by an adult woman, with two deep lesions in the anterior thorax and one superficial lesion in the upper abdomen and admitted in intensive care unit with septic shock and a persistent aortic murmur. Echocardiography described evidence of vegetation, perforation and severe regurgitation of aortic valve. Scanner described moderate pericardial effusion. Cardiac surgery was performed, with evidence of purulent pericardial effusion after pericardiotomy, and subsequently aortic valve replacement with a 25mm bioprosthesis. The patient showed positive progress.
