Atrioventricular Synchronous Pacing Using a Leadless Ventricular Pacemaker: Results From the MARVEL 2 Study.

Implantation of leadless pacing systems in patients early after tricuspid valve surgery: A feasible option.

Dual-chamber pacing using a hybrid transvenous and leadless pacing approach.

First percutaneous Micra leadless pacemaker implantation and tricuspid valve repair with MitraClip NT for lead-associated severe tricuspid regurgitation.Accelerometer-based atrioventricular synchronous pacing with a ventricular leadless pacemaker: Results from the Micra atrioventricular feasibility studies.This was performed after TLE for severe lead-related TR. DISCUSSION: We present the first case of successful implementation of AV sequential pacing using a dual-pacemaker approach involving the use of an AAI pacemaker and a Micra AV device.

A Micra AV was implanted allowing for atrioventricular (AV) synchronous pacing. The atrial lead was preserved and connected to and AAI device. Transvenous extraction of the right ventricular lead was performed. This was reserved as an option in the event of persistent severe TR. A decision was made to perform a TLE and implant a leadless pacemaker in an attempt to avoid open-heart surgery if possible. Her case was discussed in our multi-disciplinary team meeting. Echocardiography revealed severe lead-related TR. Her medical history included a dual-chamber pacemaker implantation for sinus node dysfunction 14 years ago. CASE SUMMARY: A 66-year-old woman presented with a year-long history of exertional dyspnoea, peripheral oedema, and postural neck pulsations.

Placement of pacing leads across the TV is generally avoided in such circumstances. Multiple approaches to pacemaker implantation after transvenous lead extraction (TLE) or surgical TV repair have been described. This develops through several mechanisms including the failure of leaflet coaptation or direct damage to the TV or to its sub-valvular apparatus and can result in significant tricuspid regurgitation (TR).
