Cardiovocal syndrome is a rare clinical diagnosis that signifies vocal cord palsy associated with various cardiovascular diseases. The radiological manifestations of six cases of clinically diagnosed cardiovocal syndrome are reviewed retrospectively. The common clinical presentation of these six cases was hoarseness that was due to left vocal cord palsy. By means of chest X-rays (CXR) and cardioangiography, four cases were respectively diagnosed to have atrial septal defect (n = 1), ventricular septal defect (n = 1) and mitral stenosis (n = 2), all of which were associated with a common radiological finding of dilatation of pulmonary trunk. The other two cases were separately diagnosed to have proximal descending aortic saccular aneurysm (n = 1) by means of CXR and angiography, and fusiform ascending aortic aneurysm (n = 1) by computed tomography and magnetic resonance image. All these radiological presentations of either aortic aneurysm or dilated pulmonary trunk were associated with encroachment of aorticopulmonary window for which the left recurrent laryngeal nerve was presumably compressed with the result of left vocal cord palsy. Hoarseness that is caused by these underlying cardiovascular diseases is correctable after treatment of the underlying diseases. Hence, clinicians and radiologists should pay attention to the radiological manifestations of patients whose chief complaints are hoarseness and cardiovocal syndrome.
心血管性发声障碍综合征是一种罕见的临床诊断，指与各种心血管疾病相关的声带麻痹。回顾性分析6例临床诊断为心血管性发声障碍综合征患者的影像学表现。这6例患者的常见临床表现为因左侧声带麻痹导致的声音嘶哑。通过胸部X线（CXR）和心血管造影，4例分别诊断为房间隔缺损（n = 1）、室间隔缺损（n = 1）和二尖瓣狭窄（n = 2），所有这些均伴有肺动脉主干扩张这一常见影像学表现。另外2例，1例通过CXR和血管造影分别诊断为降主动脉近端囊状动脉瘤，另1例通过计算机断层扫描和磁共振成像诊断为升主动脉梭形动脉瘤。所有这些主动脉瘤或扩张的肺动脉主干的影像学表现均与主动脉肺窗受压有关，推测左侧喉返神经因此受压，导致左侧声带麻痹。由这些潜在心血管疾病引起的声音嘶哑在治疗潜在疾病后是可纠正的。因此，临床医生和放射科医生应注意以声音嘶哑为主诉的患者及心血管性发声障碍综合征患者的影像学表现。
