Brucellosis endocarditis is a zoonosis infection of cardiovascular system with world-wide distribution, which is endemic in many provinces of the Iran. The present report describes an exceptional case of fistulization between the aorta and pulmonary artery by Brucella melitensis in a 34-year-old patient. He presented with the complaints of fever and weight loss and congestive heart failure. He was strongly positive for Brucellosis by serological reaction and conventional microbiological cultures from blood and valve tissue were positive. Echocardiography revealed aortic root abscess, cavity formation in aortic ring, large vegetation and native aortic valve destruction with aortic regurgitation and fistula from non-coronary sinus to pulmonary artery and pericarditis. The patient underwent open heart surgery with aortic valve replacement and transpulmonary fistula repair. The patient had uneven full postoperative recovery and with good general condition discharged to home in 16 th days of hospitalization.
