Careful Auscultation after Detection of Bacteremia Leading to a Diagnosis of Patent Ductus Arteriosus in Adult

抄録

A 40-year-old woman visited our emergency room (ER) with fever and shaking chills. Blood cultures for suspicion of urinary tract infection revealed bacteremia two days later. Since Streptococcus mitis was detected, infective endocarditis was strongly suspected. In addition to her history of dental calculus removal, careful cardiac auscultation revealed a continuous murmur, leading to the existence of patent ductus arteriosus (PDA). PDA was confirmed by echocardiography and 3D-CT angiography. The patient was successfully treated by antibiotics and then received transcatheter PDA closure. Careful auscultation after detection of bacteremia led to a diagnosis of PDA.
