Five patients with cardiovascular disease presented with hoarseness due to left recurrent laryngeal nerve palsy. One had secundum atrial septal defect, one had ventricular septal defect, two had mitral stenosis and the other had aortic aneurysm. All except the patient with aortic aneurysm had pulmonary artery dilatation and moderate to severe pulmonary hypertension. Four patients' hoarseness resolved after successful interventional therapy. As for the patient with the aortic aneurysm, hoarseness persisted; the patient died before surgery. We postulate that the dilated pulmonary artery or aortic arch was responsible for the compression of the left recurrent laryngeal nerve.
5例心血管疾病患者因左侧喉返神经麻痹出现声音嘶哑。1例患有继发孔房间隔缺损，1例患有室间隔缺损，2例患有二尖瓣狭窄，另1例患有主动脉瘤。除主动脉瘤患者外，所有患者均有肺动脉扩张及中度至重度肺动脉高压。4例患者在成功进行介入治疗后声音嘶哑症状消失。至于主动脉瘤患者，声音嘶哑持续存在；该患者在手术前死亡。我们推测扩张的肺动脉或主动脉弓是导致左侧喉返神经受压的原因。
