Infective Endocarditis of the Left Main to Right Atrial Coronary Cameral Fistula

A 7-year-old female child presented with pyrexia of unknown origin. She had received an empirical regimen of antibiotic for possible endocarditis. Evaluation included multiple imaging supports and blood culture. She had left main coronary artery to right atrium coronary cameral fistula, restricted patent ductus arteriosus, vegetation at the right atrial exit of fistula and negative blood culture. Ongoing fever more than 2 weeks, oscillating vegetation in the echo and histopathological evidence of healing vegetation suggested definite diagnosis of infective endocarditis. She was treated successfully by surgical closure of fistula from the right atrial approach. Device closure in this case would have resulted in a large residual cul-de-sac with or without tiny residual high-velocity jets, either being a threat for future enlargement, rupture of the residual aneurysmal sac, thromboembolism, prolonged anticoagulation, and infective endocarditis.
