Leadless Pacemaker Pitfalls

Year: 2025

Type: article

Abstract: BACKGROUND: Leadless pacemakers (LPs) are implanted into the right ventricular septum, eliminating intravascular complications associated with traditional pacemakers. They attach to the myocardium using 4 curved, self-expanding nitinol tines. CASE SUMMARY: Our case highlights the rare occurrence of LP dislodgement into the pulmonary artery and the delayed development of a traumatic right ventricular apical pseudoaneurysm. DISCUSSION: LPs were designed to reduce the lead- and pocket-related complications that can be seen with conventional pacemakers. However, LPs carry a risk of dislodgement and embolization into the pulmonary artery compared with conventional pacemakers. TAKE-HOME MESSAGES: This case explores the complexities and risks involved in both the implantation and retrieval of LPs in high-risk patient populations and highlights the importance of meticulous technique in retrieving an acutely embolized LP from the right PA.
