Pacemaker lead-induced tricuspid stenosis treated with percutaneous valvotomy

Area of Science:

• Cardiology
• Cardiac Electrophysiology
• Interventional Cardiology

Background:

• Tricuspid stenosis is an infrequent complication following ventricular pacemaker electrode implantation.
• Few documented cases exist in medical literature, highlighting its rarity.

Observation:

• An 18-year-old male presented with severe tricuspid stenosis.
• The condition developed 15 years after receiving an endocardial VVI pacemaker for complete atrioventricular block.
• The initial cardiac issue was a surgically repaired ventricular septal defect.

Findings:

• Percutaneous balloon valvuloplasty was successfully performed in this case.
• The procedure effectively treated the severe tricuspid stenosis.

Implications:

• Percutaneous balloon valvuloplasty is a feasible and successful treatment for pacemaker-induced tricuspid stenosis.
• This case expands the understanding of managing rare cardiac complications associated with long-term pacemaker use.
• Highlights the importance of monitoring for valvular complications in patients with implanted cardiac devices.
