Tricuspid Valve Regurgitation Following Temporary or Permanent Endocardial Lead Insertion, and the Impact of Cardiac Resynchronization Therapy

BACKGROUND: While some studies indicate that permanent pacemaker implantation is associated with development of tricuspid regurgitation (TR), other studies indicate no association.Little is known about the impact of temporary lead insertion during ablation procedures, or whether therapy (CRT) prevents TR post-device implantation. HYPOTHESIS: We hypothesized that permanent, but nottemporary endocardial leads, are associated with development of …
