Intracardiac fistulas are rare complications of infective endocarditis. We report an unusual case of successful surgical repair of intracardiac fistula between the left ventricle and the left atrium in the course of infective endocarditis in a 20-year-old patient. According to this we conclude that timely diagnosis, proper antibiotic treatment, and early surgical intervention should improve the outcomes of infective endocarditis complications.
