Hoarse voice, first symptom of severe pulmonary hypertension

Abstract Hoarseness of voice resulting from left recurrent laryngeal nerve (RLN) palsy. Ortner's or cardiovocal syndrome, is a rare clinical entity manifesting by hoarseness of voice due to left RLN palsy, secondary to cardiovascular disease. Dilated main pulmonary artery may lead to nerve compression between the aorta and pulmonary artery within the aortic window. We report a rare case of a patient suffering from hoarseness of voice that was the first symptom of unknown severe pulmonary arterial hypertension.
