摘要
目的:利用CT三维成像技术研究心房颤动(房颤)患者左房结构的形态学特点。方法:利用西门子16层螺旋CT作36例房颤患者[23例男性,年龄(51±12岁)]与21例非房颤患者[12例男性,年龄(46±11)岁]的心脏扫描,研究左心房的结构形态学特点并作对比分析。结果:房颤组与非房颤组相比左心房容积和左心耳较大,差异有统计学意义;二者的左心耳位置、左心耳-肺静脉脊(房颤组:长2·8±0·5,宽0·4±0·1;非房颤组:长2·7±0·4,宽0·4±0·1)和左心房顶部的形态学特点无明显差异;房颤组肺静脉开口异常率高达17%,非房颤组为10%,2组相比较差异无统计学意义。结论:房颤患者有着较大的左心房和左心耳,在左心耳位置、左心耳-肺静脉脊、左心房顶部和肺静脉开口等特殊解剖结构上与非房颤患者无差别。这些发现对减少射频消融术并发症及改进手术方法等方面能提供有用信息。
Objective：Use 16-slice multidector computed tomography （CT） to investigate the anatomy of the left atrium （LA） of patients with atrial fibrillation （AF）. Methods： Multidetector CT scan was used to depict the left atrium in 36 patients with AF （23 males, age： 51±12 years） and 21 patients without AF （12 males, age=46 ±11 years）. Results： The area of left atrial appendage （LAA）, LA volume and distance of LA roof were greater in AF group than those in without AF group. The morphologic characteristics of LAA location, LAA ridge （AF group： length 2.8±0.5, width 0.4±0.1; without AF group： length 2.7±0.4, width 0.4±0. 1） and LA roof were described, there were no difference between two groups. The incidence of abnormal pulmonary venous （PV） orifice was 17% in AF group and 10% in without AF group, there was no significant difference between them. Conclusion：The LA and LAA were larger in patients with AF than those in patients without AF. Peculiar structure, including LAA location, LAA ridge, LA roof and PV orifice had no differences between two groups. These finding can provide very useful information for avoiding complication and improving the strategy of AF ablation.
