Key result
Surgical resection of a giant RA myxoma and tricuspid annuloplasty resolves right heart failure.
Why the study?
Right atrial myxoma is a rare anomaly that can rarely obstruct right cardiac blood flow, prompting the report of a rare giant case causing right heart failure from tricuspid valve obstruction.

Surgical resection is an effective and appropriate treatment for giant right atrial myxoma causing tricuspid valve obstruction and right heart failure.
Supports surgical resection for symptomatic giant right atrial myxoma; extends sparse case reports but leaves open need for larger series.
BACKGROUND: Right atrial myxoma is a rare anomaly. 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. CASE PRESENTATION: 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 mm × 63 mm 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. The postoperative course was uneventful and the patient was discharged on postoperative day 5. CONCLUSION: Giant right atrial myxoma is a rare cause of tricuspid valve stenosis and right heart failure. Surgical resection is the most appropriate treatment option and should be performed as soon as possible after diagnosis.

Numaguchi et al. (2020) conducted a case report in Giant right atrial myxoma (n=1). Surgical resection and tricuspid valve annuloplasty was evaluated on Successful surgical excision and recovery. Surgical resection of a 57 mm × 63 mm giant right atrial myxoma, along with tricuspid valve annuloplasty, successfully treated right heart failure in a 59-year-old woman.
