Abstract: | Abstract We report the case of a 52-year-old man who presented with a cardiac metastasis of myxoid liposarcoma invading the atrioventricular sulcus. The tumor was arising from the anterior wall of the right atrium and basal right ventricle. After complete resection of the tumor (14 × 7.5 × 6 cm, 279 g), the annulus had no strong supporting tissue because of invasion of the atrioventricular sulcus. The tricuspid valve was reconstructed with reinforcement of the annulus using an autologous pericardial strip. The defect of the right atrial wall was reconstructed with a pericardial patch. After the reconstruction, echocardiography showed grade 1 tricuspid regurgitation. Although the patient had a small metastasis to the lung after surgery, he is doing well after 31-month follow-up. We believe that it is justified to perform aggressive resection with annuloplasty, when it is feasible, for cardiac metastasis of myxoid liposarcoma. |
