摘    要:
目的利用超声心动图研究二叶主动脉瓣(BAV)患者胸主动脉的形态学特征。方法回顾性分析1991年4月至2006年2月诊断的273例BAV患者的超声心动图及临床资料。结果(1)无明显主动脉瓣(AV)病变的BAV患者的主动脉瓣环、窦部、窦管结合部、升主动脉较正常对照组明显增宽(P≤0.001);而二者胸降主动脉比较差异无统计学意义(P=0.061)。(2)BAV患者的AV排列位置对各级胸主动脉内径无影响(P〉0.05)。(3)主动脉瓣环、窦部内径与AV最大压力阶差、平均压力阶差呈低度负相关;主动脉瓣环、窦部、窦管结合部内径与AV反流程度呈低度正相关。结论BAV患者的胸主动脉可发生独立于血流动力学影响之外的扩张。AV的功能变化对胸主动脉内径影响略有不同。在临床上,主动脉内径可作为手术时机选择的参考指标。

Abstract:
OBJECTIVE: To observe the thoracic arota features in patients with bicuspid aortic valve (BAV) with echocardiography. METHODS: We retrospectively analyzed the echocardiographic features and clinical manifestations in 273 patients with BAV detected from 1991-04 to 2006-02. RESULTS: (1) Aortic dimensions of the anulus, the sinuses of valsalva, the sinotubular junction, the ascending aorta at the level of its largest diameter of 31 patients with functionally normal BAV were significantly increased compared that in control subjects (P < 0.01 to P < 0.001) while the dimension of the descending aorta posterior to the left atrium was similar between the two groups (P > 0.05). (2) There is no relation between the valval positions of BAV and aortic dimensions (P > 0.05). (3) The dimensions of the annulus as well as the sinuses of valsalva were negatively related to the aortic valve gradiet, and the dimension of the annulus, the sinuses of valsalva and sinotubular junction were positively related to the degree of aortic regurgitation in 273 patients with BAV (all P < 0.05). CONCLUSION: Our results show there is a hemodynamic independent thoracic aortic dilation in patients with functionally normal BAV. Gradient and aortic regurgitation are related to the dimension of the annulus, the sinuses of valsalva and sinotubular junction in patients with BAV.
