Leadless Pacemaker Pitfalls: Navigating Implantation and Postprocedure Challenges.

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.
