Study report a 42-years-old female came with complaints of dyspnoea on exertion, and recurrent cough for past one year. She gives history of significant weight loss for the past 6 months. Trans thoracic echocardiogram showed large pedunculated myxoma measuring 28*18 mm attached to posterior wall of right atrium extending into right ventricle and outflow tract. Computed tomography pulmonary angiogram showed acute bilateral pulmonary thromboembolism with left upper lobe infarct. She underwent complete removal of the tumour along with patch of atrial wall with pulmonary embolectomy using Fogarty baloon catheter through median sternotomy. Her postoperative course was uneventful. This case is reported for its rarity of presentation of right atrial myxoma with pulmonary embolism.
