Catheter based therapy of cor triatriatum sinister - case report

Cor triatriatum sinister (CTS) is a rare cardiac congenital anomaly. Left atrium is separated by the membrane which is the cause of obstruction in blood flow from pulmonic veins to mitral valve, and mimicks the clinic manifestation of mitral stenosis with pulmonic congestion and pulmonary hypertension. Surgical resection of the membrane is the best option, but there is also possibility of transcatheter intervention. We here present the patient with the anomaly of CTS, who underwent cardiac catheterization and successful balloon dilatation of the orifice in the membrane with positive haemodynamic and clinical result.
