Summary
A novel three-step snare technique successfully guided a leadless pacemaker across a rigid tricuspid annuloplasty ring. This method ensured stable septal fixation, overcoming delivery challenges in a complex cardiac patient.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Medical Device Technology
Background:
- Leadless pacemaker implantation can be technically difficult in patients with prior cardiac surgery, particularly after tricuspid annuloplasty with rigid rings.
- Standard delivery techniques may fail to navigate the rigid annuloplasty ring, preventing successful pacemaker implantation.
- Complex patient histories, including prior valve repair and Maze procedures, add to the challenge of cardiac device implantation.
