      Abstract

      Although recommended for a number of diagnostic and therapeutic procedures in patients at increased risk for infective endocarditis, antibiotic prophylaxis is generally not considered necessary for upper gastrointestinal endoscopy.1,2 Thus, the recent recommendation for antibiotic prophylaxis in transesophageal echocardiography3 is somewhat surprising. With the increasing number of transesophageal examinations, the matter clearly needs the cardiologists' attention. In this article, we report on the incidence and nature of positive blood cultures and smear samples from the echo probe of patients undergoing transesophageal echocardiography in our department.
