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.

Background: Removal of cardiac implantable electronic devices (CIEDs) is strongly recommended for CIED-related infections, and leadless pacemakers (LPs) are increasingly used for reimplantation. However, the optimal timing and safety of LP implantation after CIED removal for infection remains unclear.This systematic review and meta-analysis aimed to assess complication rates (all-cause mortality and reinfection) when LP implantation was performed simultaneously with or after CIED removal.

Article Synopsis
- Single-chamber right ventricular leadless pacemakers are already established, and the new right atrial leadless pacemakers allow for dual-chamber pacing.
- A 58-year-old male with dizziness and complete heart block received a single-chamber leadless pacemaker, and during an upgrade to dual-chamber pacing, 3D CT image fusion was used for safe implantation.
- The combination of CT imaging and fluoroscopy may improve procedural safety, increase success rates, and decrease the time spent using fluoroscopy.
Advanced Speckle-Tracking Echocardiography Could Play a Crucial Role in the Diagnosis of Post-Implanted Cardiomyopathy Associated with a Leadless Pacemaker System.

A leadless pacemaker (LP) is a modern alternative to a transvenous pacemaker, allowing certain complications to be avoided; however, some cannot be eliminated. To highlight the essential role of advanced speckle-tracking echocardiography (STE) in diagnosing pacing-induced cardiomyopathy (PICM) caused by an LP. A 79-year-old male, after LP implantation a year earlier, was admitted due to heart failure (HF).
