PO-01-222 TRANSCATHETER RETRIEVAL OF DISLODGED MICRA PACEMAKER IN SURGICALLY-REPAIRED CONGENITAL ANATOMY

HeartRhythm

MARCH 31, 2025

A 27-year-old male with Tetralogy of Fallot, RV-PA conduit, TVR, AV block with TV-sparing dual pacemaker (RA and CS leads) and abandoned epicardial PM, presented with MSSA endocarditis and underwent emergent transcatheter valve-in-valve TVR. Subsequent sternotomy allowed TVR and leadless (Medtronic Micra AV) PM placement in the RV.

PO-01-085 NAVIGATING ANATOMIC CHALLENGES: A SNARE TECHNIQUE FOR SUCCESSFUL LEADLESS PACEMAKER IMPLANTATION

HeartRhythm

MARCH 31, 2025

Leadless pacemakers offer a promising alternative to traditional transvenous systems for patients at high risk of complications. We present a case where an innovative snare technique was employed to navigate difficult anatomy. We present a case where an innovative snare technique was employed to navigate difficult anatomy.

PO-FP-033 LONG-TERM OUTCOMES OF PERMANENT PACEMAKER IMPLANTATION AFTER HEART TRANSPLANTATION: A LARGE INSTITUTIONAL EXPERIENCE

HeartRhythm

MARCH 31, 2025

Up to 10% of patients require permanent pacemaker (PPM) implantation after orthotopic heart transplant (OHT). These patients present a challenge due to altered postsurgical anatomy and increased susceptibility to infection due to immunosuppression.

Leadless pacemakers are an alternative to transvenous devices for patients at high risk for lead-related complications. However, conventional implantation is done via femoral access, which may not be possible in cases with variant venous anatomy like interrupted IVC.

Snare‐Assisted Flexion of 27‐French Leadless Pacemaker Delivery Sheath: A Case Report

Journal of Cardiovascular Electrophysiology

JANUARY 24, 2025

ABSTRACT Introduction A leadless pacemaker (LLPM) was recommended for a patient with intermittent complete heart block and near-syncope. Methods and Results Delivery of LLPM is through a large sheath that has limited deflection and steerability. The ventricular LLPM was successfully fixated.

Methods We present the first described case of using two leadless pacing systems manufactured by separate companies implanted within the same patient to provide atrial and ventricular pacing due to complex congenital anatomy. Laser-lead extraction and temporary atrial pacemaker placement was performed.

HeartRhythm

MARCH 31, 2025

Patients with congenitally corrected transposition of the great arteries (ccTGA) develop complete heart block (CHB) necessitating permanent pacemakers (PPM). Given complex anatomy, access to coronary sinus may be challenging. Left bundle branch pacing (LBBAP) is an alternative to CRT, however, its effects in SRV remain unknown.

A temporary pacemaker was implanted, and she was admitted to the ICU with cardiogenic shock. Prompt cath to define the anatomy should be expedited. She was worked as a full code, and ROSC was achieved. She was taken to the cath lab, where she was found to have 100% in-stent restenosis of the proximal LAD. She could not be resuscitated.

To revise the anatomy lessons, this is the external jugular vein and this is the internal jugular vein. Thrombus can sometimes occur when there is a central venous catheter or a multiple pacemaker or defibrillator leads there that can cause thrombus formation. Obstruction could be due to tumour or even a thrombus.
