A 16-year-old girl was admitted with a 7-month history of recurrent fever, weight loss of 5 kg, and general poor health status. Blood culture was positive with Streptococcus viridans. Transthoracic echocardiography established an aneurysm of the root of left subclavian artery, associated with an aortic coarctation just before the origin of the left subclavian artery with a velocity of 4.8 cm/s. Three-dimensional echocardiography demonstrated the entire inner structure of the aneurysm. Computed tomography reconstruction confirmed the presence of aortic coarctation and mycotic aneurysm, it also revealed an aberrant right subclavian artery.
