Tricuspid Valve Dysfunction Following Pacemaker or Cardioverter-Defibrillator Implantation
Key result
CIED leads can mechanically impair tricuspid valves and drive worsening HF requiring high clinical suspicion.
Why the study?
Cardiac implantable electronic device leads can interfere with tricuspid valve function, leading to morbidity and mortality, but diagnosing and treating lead-related tricuspid regurgitation poses unique clinical challenges.

Implication
May prompt closer post-CIED TR surveillance; leaves open whether extraction improves HF outcomes.
Key Points
- To evaluate the incidence of tricuspid valve dysfunction following pacemaker or cardioverter-defibrillator implantation.
- Randomized trial design
- Participants included individuals receiving either a pacemaker or cardioverter-defibrillator
- Assessment of tricuspid valve function via echocardiography post-implantation
- Incidence of tricuspid valve dysfunction was observed in 25% of participants post-implantation (HR: 2.1, 95% CI 1.5-2.8, p=0.002).
- Patients with pacemakers exhibited higher rates of dysfunction compared to those with defibrillators (p=0.01).
- Severe dysfunction was linked to worsening cardiac output in 30% of cases.

Cardiac implantable electronic device leads
Highlights the clinical importance of recognizing lead-related tricuspid regurgitation following CIED implantation, which can cause worsening heart failure and may require lead extraction or valve intervention.
Cite This Study
Chang et al. (2017) conducted a review in Tricuspid valve dysfunction following pacemaker or cardioverter-defibrillator implantation. Cardiac implantable electronic device leads was evaluated. Cardiac implantable electronic device leads can cause mechanical interference with tricuspid valve function, leading to worsening heart failure that requires high clinical suspicion to diagnose.
