目的记录64层心脏CT显示的左心房附件的数量和解剖形状的频率和变化。方法和材料回顾性分析了166例患者6个月内使用64层ECG门控CT扫描仪进行的冠状动脉CT血管造影采集协议所描述的左心房解剖结构（Siemens Medical Solutions）当地IRB豁免了本回顾性研究的知情同意书。结构小于5毫米的形状被排除在外，以及大的副肺veines.Results17（17）166例（10%）有18个附件左心耳（只有一个病人有两个）。15个附件位于沿着右上心房壁，测量值为0.9 × 0.6 × 0.5 cm 3 ± 0.2 × 0.2 × 0.1（1型）。3例位于左下心房壁沿着，较大（横截面0.9-2.5 cm）（2型）。右上附件大多形状像小憩室和左下的形状像平坦的花椰菜expansions.Conclusionsaccessory左心耳可视化在10%的166例患者在64层螺旋CT冠状动脉造影。
PurposeTo document the frequency and variations in number and anatomical shape of accessory appendages of the left atrium as seen on 64-slice cardiac CT.Methods and materialsRetrospective review of the anatomy of the left atrium as depicted by cardiac CT using the acquisition protocol designed for coronary CT Angiography and performed in 166 patients over a 6-month period with a 64-slice ECG-gated CT scanner (Siemens Medical Solutions). The local IRB provided a waiver of informed consent for this retrospective study. Structures less than 5 mm in shape were excluded, as well as large accessory pulmonary veins.ResultsSeventeen (17) of 166 patients (10%) had 18 accessory left atrial appendages (only one patient had two). Fifteen (15) accessory appendages were located along the right upper atrial wall and measured 0.9 × 0.6 × 0.5 cm3 ± 0.2 × 0.2 × 0.1 (Type 1). Three (3) were located along the left lower atrial wall, and were larger (0.9–2.5 cm cross-section) (Type 2). The right upper accessory appendages were mostly shaped like small diverticuli and the left lower ones were shaped like flat cauliflower expansions.ConclusionsAccessory left atrial appendages were visualized in 10% of 166 patients during 64-slice coronary CT angiography.
