A Case of Dyspnea in a Patient with a Previous Coronavirus Disease Infection: Pulmonary is not always the Cause

Myxoma is the most common benign primary tumor of the heart. Diagnosis of cardiac myxoma is difficult as it presents itself with varying nonspecific symptoms, and an echocardiography can easily diagnose it. Sometimes, it can cause cardiac syncope and thromboembolic events. A woman with a recent infection by severe acute respiratory syndrome coronavirus-2 was admitted to our hospital with respiratory symptoms: dyspnea and tachypnea; cardiac symptoms: atrial fibrillation; and neurological symptoms: syncope. Initially, she performed brain computed tomography (CT) and CT angiography value. Transthoracic echocardiogram and transesophageal echocardiogram showed an atrial mobile mass. Chest X-ray did not show any interstitial lesions. Therefore, urgent cardiac surgery was performed to remove the mass. The histological examination confirmed the presence of a cardiac myxoma. Our experience could show the importance of early diagnosis and prompt surgical treatment to prevent stroke.
