Lead helix winding tricuspid chordae tendineae: A case report

BACKGROUND: As left bundle branch pacing (LBBP) is more like physiological pacing, LBBP has emerged as a novel pacing strategy that uses the native conduction system to improve ventricular synchronization with stable pacing parameters. LBBP has been revealed associated with a significantly reduced r...

description BACKGROUND: As left bundle branch pacing (LBBP) is more like physiological pacing, LBBP has emerged as a novel pacing strategy that uses the native conduction system to improve ventricular synchronization with stable pacing parameters. LBBP has been revealed associated with a significantly reduced risk of new-onset atrial fibrillation and heart failure compared with conventional permanent pacemaker implantation. CASE SUMMARY: A 64-year-old man was admitted with a 24-h history of chest distress and shortness of breath, which continued unabated. The patient had no symptoms of chest pain, dizziness, syncope, nausea nor vomiting. There were no abnormalities found in routine examinations after admission. Twelve-lead electrocardiogram presented a result of 2:1 atrioventricular block. Coronary angiography was performed the next day and no abnormality was found. Finally, the patient agreed to received LBBP and signed the informed consent. During the process of withdrawing the Medtronic Model 3830 lead into sheath, we found the lead helix was wrapped around the chordae tendineae of the septal valve of tricuspid. Attempts to rotate the 3830 lead failed to release the lead helix from the chordae tendineae, and ultimately we used radiofrequency ablation to ablate the wrapped chordae tendineae. CONCLUSION: Radiofrequency ablation effectively solved this problem without complications. It is an effective and reliable method to resolve lead winding chordae.
