尽管左心房（LA）应变已使用经胸超声心动图（TTE）得到充分验证，但其使用经食管超声心动图（TEE）的可行性尚未研究。已知常规经食管视图由于左心房的后部位置而受到限制。在这里，我们测试的可行性和准确性的深经胃长轴LA聚焦视图的峰值心房纵向应变（帕尔斯）量化。这是一项对2018年至2020年期间接受择期心脏手术的患者进行的回顾性研究。TEE经胃深长轴切面与TTE四腔心房聚焦切面作为参考标准进行比较。LA面积、体积和帕尔斯独立定量。威尔康奈尔医学，一个单一的大型学术医疗中心。该人群包括42例接受心脏手术的患者，他们在14.9 ± 20.8天内进行了TTE和TEE。TTE，TEE，心脏手术。TEE衍生的帕尔斯与TTE衍生的帕尔斯密切相关（r=0.92，p<0.001），但绝对帕尔斯较低（20.7±6.0% vs. 25.7±6.8%; p<0.001）。TEE得出的平均心房长度与TTE得出的长度相似（5.18±0.61 cm vs. 5.24±0.61 cm;p=0.38），但平均LA面积显著较小（16.7±3.5 cm 2 vs. 18.9±3.7 cm 2; p<0.001），两种模式之间存在显著相关性（r分别为0.74、0.74;所有p<0.001）。该探索性研究支持TEE评估LA纵向应变的可行性。通过TEE与TTE得出的心房应变之间存在良好的相关性，尽管TEE上的值往往较小，并且值之间的偏倚高度可变，表明值不可互换。
Whereas left atrial (LA) strain has been well-validated using transthoracic echocardiography (TTE), its feasibility using transesophageal echocardiography (TEE) has not been studied. Conventional transesophageal views are known to be limited due to the posterior location of the LA. Here, we test the feasibility and accuracy of the deep transgastric long-axis LA focused view for peak atrial longitudinal strain (PALS) quantification. This is a retrospective study of patients who underwent elective cardiac surgery between 2018 to 2020. TEE deep transgastric long-axis view was compared to TTE 4-chamber atrial focused view as the reference standard. LA area, volume, and PALS were quantified independently. Weill Cornell Medicine, a single large academic medical center. The population comprised of 42 patients undergoing cardiac surgery who had a TTE and TEE within 14.9 ± 20.8 days. TTE, TEE, cardiac surgery. TEE-derived PALS strongly correlated with TTE derived PALS (r=0.92, p<0.001) though absolute PALS were lower (20.7±6.0% vs. 25.7±6.8%; p<0.001). Mean TEE-derived atrial length was similar to TTE-derived length (5.18±0.61 cm vs. 5.24±0.61 cm;p=0.38) but mean LA area was significantly smaller (16.7±3.5 cm2 vs. 18.9±3.7 cm2; p<0.001), with significant correlations between the two modalities for both (r=0.74, 0.74 respectively ;all p<0.001). This exploratory study supports the feasibility of TEE for assessing LA longitudinal strain. There is an excellent correlation between atrial strain derived via TEE vs. TTE although values tended to be smaller on TEE, and bias between values were highly variable, suggesting that values were not interchangeable.
