Background: Damage to the tricuspid valve (TVD) is now considered either a major or minor complication of the transvenous lead extraction procedure (TLE). As yet, the risk factors and long-term survival after TLE in patients with TVD have not been analyzed in detail. Methods: This post hoc analysis used clinical data of 2631 patients (mean age 66.86 years, 39.64% females) who underwent TLE procedures performed in three high-volume centers. The risk factors and long-term survival of patients with worsening tricuspid valve (TV) function after TLE were analyzed. Results: In most procedures (90.31%), TLE had no negative influence on TV function, but in 9.69% of patients, a worsening of tricuspid regurgitation (TR) to varying degrees was noted, including significant dysfunction in 2.54% of patients. Risk factors of TLE relating to severe TVD were: TLE of pacing leads (5.264; p = 0.029), dwell time of the oldest extracted lead (OR = 1.076; p = 0.032), strong connective scar tissue connecting a lead with tricuspid apparatus (OR = 5.720; p < 0.001), and strong connective scar tissue connecting a lead with the right ventricle wall (OR = 8.312; p < 0.001). Long-term survival (1650 ± 1201 [1–5519] days) of patients with severe TR was comparable to patients without tricuspid damage related to TLE. Conclusions: Severe tricuspid valve damage related to TLE is relatively rare (2.5%). The main risk factors for the worsening of TV function are associated with a longer lead dwell time (more often the pacing lead), causing stronger connective tissue scars connecting the lead to the tricuspid apparatus and right ventricle. TVD is unlikely to affect long-term survival after TLE.
