Background: The aim of this study is to investigate the role and method of intracardiac echocardiography (ICE) in left bundle branch pacing. Subjects and Methods: A total of 12 patients who underwent ICE-guided left bundle branch pacing from February 2018 to June 2018 in the Department of Cardiology of the First People's Hospital of Yunnan Province were enrolled in this observational case analysis. The study was approved by the Institutional Ethical Committee of the First People's Hospital of Yunnan Province, China (approval No. KHLL2019-KY018). The patients' sex, age, weight, disease history, and the results of color Doppler echocardiography were recorded before surgery. The duration of surgery, X-ray exposure, pacing parameters (threshold, perception, and impedance), electrocardiogram characteristics, pacing parameters, clinical symptoms, and echocardiographic results were recorded after surgery. Results: The left bundle branch pacing guided by ICE was successfully in all 12 patients. There were four cases of sick sinus syndrome, six cases of atrioventricular block, and two cases of atrial fibrillation with long R-R interval. The mean operation time was 1.75 ± 0.28 hours, and the X-ray exposure was 61.2 ± 13.6 mGy. The implantation time of left bundle branch electrode was 1.23 ± 0.24 hours, and X-ray exposure of left bundle branch electrode implantation was 48.9 ± 12.3 mGy. There was no electrode dislocation, pneumothorax, or infection after operation. Two of them had a small hematoma of the pacemaker pocket, and hematoma disappeared after compression. Conclusion: This study demonstrates the feasibility of ICE guidance for left bundle branch pacing, which may increase the success rate and reduce the risk of surgery. |
