Multimodality imaging of cor triatriatum sinister

Cor triatriatum sinister (CTS) is a very rare congenital cardiac malformation which the left atrium (LA) is divided into two chambers by a fold of tissue, a membrane, or a fibromuscular band. The anomaly is usually diagnosed in childhood, but in adult age is less common. Clinical symptoms can mimic mitral stenosis. We report a case of 54- year-old woman referred to our hospital for transoesophageal echocardiography (TEE). She had in history of dyspnea, headache, dizziness and effort intolerance for five years. 2D and 3D TEE revealed fibromembranous structure in the dilated LA. The membrane divided LA into two chambers (proximal chamber and distal chamber) Proximal chamber was receiving the pulmonary veins, and distal chamber contained left atrial appendage and mitral valve orifice. We found few fenestrations connecting the two chambers. Coronary angiography revealed normal coronary arteries. Multislice computed tomography confirmed diagnosis of CTS. The patients was referred to cardiac surgery. The atrial membrane was excised around its periphery. Recovery from the surgery was uneventful and she was asymptomatic on further hospital stay and follow-up. The diagnosis of CTS is paramount because of possibility of surgical repair with excellent long-term prognosis. 3D TEE is noninvasive method for comprehensive imaging and correct diagnosis of this rare congenital malformation.
