When present, it can rarely cause blood flow obstruction in the right cardiac chamber depending on its size and location. We herein report a rare case of a giant right atrial myxoma, which caused right heart failure due to tricuspid valve obstruction, along with our treatment experience.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Case presentation<\/jats:title>\n<jats:p>A 59-year-old woman was admitted to our hospital for palpitations and edema of the lower extremity. Computed tomography image and transthoracic echocardiography showed a 57\u2009mm \u00d7 63\u2009mm giant tumor obstructing the tricuspid valve inflow. The tumor was excised surgically and the residual septal defect was repaired with a Dacron patch. Tricuspid valve annuloplasty was performed additionally.
