Tricuspid regurgitation and infective endocarditis as a cause of lead dislodgement in left bundle branch area pacing.

BACKGROUND

According to the current literature, there is no difference between left bundle brunch area pacing (LBBAP) and right ventricular apical pacing in terms of lead dislodgement and capture threshold elevation. However, there are no large-scale studies reporting the data about long-term lead stability in patients with severe tricuspid regurgitation.

METHODS AND

RESULTS

We present a case of lead dislodgement with possible infective endocarditis six months after implantation in a patient with severe tricuspid regurgitation who underwent LBBAP.

CONCLUSIONS

We concluded that severe preoperative tricuspid regurgitation may cause lead dislodgement, and infective endocarditis may be a facilitator or main reason of lead dislodgement in cases of LBBAP.
