The TricValve bicaval valve system has emerged as a transcatheter option for patients with severe symptomatic TR who are not candidates for surgery or orthotopic interventions. However, its safety in patients with preexisting cardiac implantable electronic devices (CIEDs) remains uncertain due to potential lead-related complications. This study aims to evaluate the feasibility and safety of TricValve implantation in patients with preexisting CIED, with particular focus on lead-related complications and the need for lead extraction or repositioning.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a multicentre retrospective study including 65 patients with pre-implanted CIED who underwent TricValve implantation between May 2023 and November 2024 at 23 international centres. Pre-procedural computed tomography and echocardiography were analysed to assess device interaction, lead positioning, and complications. The primary end-point was procedural safety, including lead-related events and the need for lead extraction or repositioning during intervention. Secondary end-points included echocardiographic outcomes, CIED\/non-CIED-related complications, and survival during follow-up of 159 days (interquartile range [IQR] 60-358 days).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>TricValve implantation was technically successful in all patients (100%). Periprocedurally, no lead extraction or repositioning was required. Lead-related complications occurred in 4 patients (6.2%). No procedural deaths or TricValve malfunctions were observed. Post-implantation imaging confirmed stable lead positioning in all remaining cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>TricValve implantation in patients with preexisting CIED appears feasible.
