Safety and effectiveness of transthoracic echocardiography in left bundle branch area pacing surgery with a new type of pacemaker
Objective To explore the safety and effectiveness of transthoracic echocardiography in the left bundle branch area pacing surgery with a new type of pacemaker.Methods A retrospective study was conducted on 11 patients who suc-cessfully performed left bundle branch pacing using a new pacemaker in our hospital from February 2023 to December 2023.Basic case data such as gender,age,etiology,and conventional echocardiogram parameters were collected.2D-STI was used to obtain the maximum difference in peak time of longitudinal strain in 17 segments of the left ventricle during systole,peak strain dispersion,and standard deviation of radial strain peak time in 6 segments of the left ventricle The time difference between the peak radial strain of the left ventricular short axis anterior septum and posterior wall during systole.Results All cases were reported by charts according to International Case Report Rules.Eleven patients showed no com-plications such as ventricular septal hematoma,ventricular septal perforation,wire displacement,or rupture on ultrasound examination 3 days after surgery,and no decrease in resting state cardiac function measurement was observed.One patient showed a small amount of pericardial effusion,and all patients had varying degrees of tricuspid regurgitation.Postoperative left ventricular synchrony was good in all patients.Conclusion The application of a new pacemaker in pacing the left bun-dle branch area is safe and reliable.Transthoracic echocardiography can be used to observe the position of the implanted lead and left ventricular synchrony after implantation,and is worthy of clinical promotion.
