A case of lead helix winding tricuspid chordae tendineae

Abstract As left bundle branch pacing (LBBP) is more likely physiological pacing，which has emerged as a novel pacing strategy that uses the native conduction system to improve ventricular synchrony with stable pacing parameters. Operation process of the lead implanation was performed relatively complex, lack ofa standard operation may lead to serious consequences. Recently, we encountered a case of the lead helix was winding the tricuspid chordae. Radio frequency ablation effectively solved this problem without causing serious complications. It is an effective and reliable method to solve the problem of electrode winding chordae. This case provided more clinical experience in handing the operative complications.
