Why the study?
Cardiac myxomas are rare tumors, with only 8% occurring in the right atrium, presenting diverse clinical manifestations and diagnostic challenges.
Surgical excision provides an effective diagnostic and curative approach for rare right atrial myxomas presenting with constitutional symptoms and atrial fibrillation.
Right atrial myxoma can cause syncope; this case extends sparse reports on rare locations but leaves open questions on routine evaluation.
Myxomas are rare tumors arising from the uncontrolled proliferation of mesenchymal cells. Among cardiac conditions, cardiac myxomas account for less than 0.1% of cases, with the majority found in the left atrium and only 8% in the right atrium. Atrial myxomas present with various clinical manifestations, including constitutional symptoms, symptoms caused by blood flow obstruction, and tumor embolism. This case report describes a 50-year-old male patient presenting with syncope, fatigue, and dyspnea, who had a history of well-controlled hypertension and atrial fibrillation. Physical examination, further diagnostic workup, and echocardiography led to a provisional diagnosis of right atrial myxoma. The patient underwent a median sternotomy, and the tumor was surgically excised, resulting in both diagnostic and curative outcomes. Histological analysis confirmed the diagnosis of myxoma. This case report contributes valuable insights into the presentation, diagnostic challenges, and treatment of atrial myxoma.
