    Abstract:
    OBJECTIVES: With the expanding use of cardiac implantable electronic devices (CIEDs), lead interference with the tricuspid valve (TV) causing significant tricuspid regurgitation (TR) has gained increasing recognition. However, current knowledge about the long-term results of the surgical treatment of TR in this setting is scanty. Therefore, increasing this information was the goal of this study. METHODS: A retrospective review of our institutional database was carried out to select all patients with previously implanted CIEDs who underwent tricuspid valve repair and replacement from 2000 through 2019. Kaplan-Meier methods were used to analyse long-term survival. To describe the time course of TR, we performed a longitudinal analysis using generalized estimating equations. RESULTS: A total of 151 patients were identified. Mechanical interference with leaflet mobility and coaptation was detected in 103 patients (68%) (CIED-induced group); in the remaining 48 patients (32%), the lead was associated with TR without being the cause of it (CIED-associated group). A total of 105 patients underwent TV repair; in the remaining 46, a TV replacement was necessary. In patients who underwent TV repair, no significant difference in moderate TR recurrence rate was highlighted between CIED-induced and CIED-associated TR. CONCLUSIONS: In patients with CIEDs and surgically treated tricuspid regurgitation, TR is CIED-induced in about two-thirds of the cases and CIED-associated in one-third of them. In our experience, TV repair was still possible in 63% of the cases, with good long-term results and no significant durability difference between CIED-induced and CIED-associated TR.
