ABSTRACT
A 68-year-old man presented with a six-month history of painless dysphagia, malnutrition, anorexia and vocal hoarseness. Signs of severe mitral regurgitation and preserved left atrial dimensions were discovered on transthoracic echocardiography. However, electrocardiography and chest radiography were strongly suggestive of left atrial enlargement. Further investigations confirmed extrinsic compression of the oesophagus, which caused the dysphagia. Computed tomography of the throrax revealed a giant left atrium that was not appreciated on echocardiography. Hoarseness was found to be caused by right recurrent laryngeal nerve palsy. Ortner’s syndrome, which describes the occurrence of vocal hoarseness due to a cardiopulmonary disease that results in the compression of the left recurrent laryngeal nerve, is usually associated with severe mitral stenosis. Herein, we report an unusual case of Ortner’s syndrome caused by a giant left atrium, which resulted from severe mitral regurgitation, causing extrinsic oesophageal compression and right recurrent laryngeal nerve palsy. Physicians should remain cognisant of cardiovascular disorders as uncommon causes of painless dysphagia or vocal hoarseness.
