【摘要】 目的:三维超声心动图评估不同年龄段和性别主动脉瓣二叶畸形(bicuspid aortic valve malformation,BAV)的应用价值。方法:超声心动图检测我院2012年6月至2014年9月70例BAV患者,根据年龄段分为4组,≤20岁年龄组7例,21-40岁年龄组14例,41-60岁年龄组30例,≥60岁年龄组19例;根据性别分为2组,男性42例,女性28例。测量不同病例分组的主动脉窦部及升部内径、室间隔厚度、左心功能及左房横径,比较主动脉瓣狭窄、关闭不全、钙化及脱垂四个合并症发生率。结果:在心脏结构指标方面,年龄段分组室间隔厚度≥60岁年龄组12.37±1.64 mm高于≤20岁年龄组10.43±2.22 mm和21-40岁年龄组11.00±1.92 mm;左房横径41-60岁年龄组38.73±7.95 mm和≥60岁年龄组40.05±9.71 mm高于≤20岁年龄组29.86±1.86 mm。性别分组左心功能女性64.18±6.04%高于男性58.71±11.28%。在合并症发生率方面年龄段分组主动脉瓣狭窄41-60岁年龄组80%、≥60岁年龄组84%高于21-40岁年龄组50%,性别分组狭窄男性81%大于女性54%,关闭不全女性79%大于男性50%。结论:三维超声心动图诊断BAV可获得更加全面、具体、直观的诊断信息,BAV的超声表现与患者年龄段和性别密切相关。更多还原

【Abstract】 Objective: To assess three-dimensional echocardiographic application value of different ages and gender on bicuspid aortic valve malformation(BAV). Methods: Echocardiography in our hospital from June 2012 to September 2014 detected 70 cases of BAV patients, which were divided into 4 groups according to the age, ≤20 age group 7 cases, 21-40 age group 14 cases, 41-60 age group 30 cases, and ≥60 age group 19 cases; which were divided into 2 groups, 42 cases in male, 28 cases in female according to the gender. Measurement of different cases on internal diameterand of Aortic sinus and ascending aorta, interventricular septum thickness,left ventricular function and left atrial diameter, four complication rates were compared with aortic stenosis, regurgitation, calcification and prolapse. Results: In cardiac structure, age groups on interventricular septal thickness in ≥60 age group 12.37±1.64 mm is higher than ≤20 age group 10.43±2.22 mm and 21-40 age group 11.00±1.92 mm; left atrial diameter in 41-60 age group 38.73±7.95 mm and ≥60 age group 40.05±9.71 mm are higher than ≤20 age group 29.86±1.86 mm. Gender groups on left ventricular function in female 64.18±6.04% is greater than male 58.71±11.28%. In complication rates, age groups on aortic stenosis in 41-60 age group 80%, ≥60 age group 84% are higher than 21-40 age group 50%, gender groups on stenosis in male 81% is greater than female 54%, regurgitation in female 79% is greater than male 50%. Conclusion: Three dimensional echocardiography in the diagnosis of BAV can obtain more comprehensive and specific, intuitive diagnostic information, ultrasonography in patients with BAV is closely related to the age and gender.更多还原
