Abstract

Objective

To assess the guiding role of transesophageal echocardiography (TEE) intraoperatively and its evaluative function postoperatively during left atrial appendage occlusion (LAAO) in patients with non-organic heart disease (NOHD).

Methods

In this retrospective observational study, a total of 48 patients with NOHD who underwent LAAO in the Department of Cardiology at The First People's Hospital of Lanzhou City from April 2020 to September 2022 were recruited. TEE findings during and after the procedure, cardiac chamber size, and cardiac function parameters at different surgical stages, postoperative occlusion efficacy, and complications were recorded. The application value of TEE in LAAO for patients with NOHD was evaluated.

Results

Comparative analysis TEE-measured the maximum diameter of the LAAO (22.37 ± 3.86 mm) was significantly smaller than X-ray angiographic measurement (23.45 ± 4.22 mm; p < 0.05). One month after radiofrequency ablation, TTE revealed a statistically significant reduction in left atrial diameter (p < 0.05). Four cases (8%) exhibited minor peri-device leak (< 3 mm), and no major complications occurred.

Conclusion

TEE shows significant application value for monitoring anatomical changes, guiding device sizing, and detecting peri-device leaks during and after LAAO for patients with NOHD.

经食管超声心动图在非器质性心脏病左心耳闭塞的指导和评价中的作用

目的探讨经食管超声心动图（TEE）在非器质性心脏病（NOHD）患者左心耳闭塞（LAAO）中的术中指导作用及术后评价功能。方法本回顾性观察研究共招募了2020年4月至2022年9月在兰州市第一人民医院心内科接受LAAO治疗的48例NOHD患者。记录术中及术后TEE检查、不同手术阶段心室大小、心功能参数、术后封堵效果及并发症。评价TEE在NOHD患者LAAO中的应用价值。结果tee测得的LAAO最大直径（22.37±3.86 mm）明显小于x线血管造影测得的LAAO最大直径（23.45±4.22 mm）；p < 0.05)。射频消融1个月后，TTE显示左房内径减小有统计学意义（p < 0.05）。4例（8%）出现轻微的器械周围泄漏（3mm），未发生重大并发症。结论TEE在NOHD患者LAAO期间及术后监测解剖变化、指导器械尺寸、检测器械周围泄漏等方面具有重要的应用价值。

期刊介绍： The ANNALS OF NONINVASIVE ELECTROCARDIOLOGY (A.N.E) is an online only journal that incorporates ongoing advances in the clinical application and technology of traditional and new ECG-based techniques in the diagnosis and treatment of cardiac patients. ANE is the first journal in an evolving subspecialty that incorporates ongoing advances in the clinical application and technology of traditional and new ECG-based techniques in the diagnosis and treatment of cardiac patients. The publication includes topics related to 12-lead, exercise and high-resolution electrocardiography, arrhythmias, ischemia, repolarization phenomena, heart rate variability, circadian rhythms, bioengineering technology, signal-averaged ECGs, T-wave alternans and automatic external defibrillation. ANE publishes peer-reviewed articles of interest to clinicians and researchers in the field of noninvasive electrocardiology. Original research, clinical studies, state-of-the-art reviews, case reports, technical notes, and letters to the editors will be published to meet future demands in this field.
