Abstrakt:	Introduction and Aims: Tricuspid regurgitation (TR) induced by the implantation of cardiac implantable electronic devices (CIED) is an increasingly common cause of severe TR. Our aim was to describe the echocardiographic phenotypic characteristics of CIED-induced severe TR. Methods: Retrospective cohort study that included patients with severe TR related to CIED diagnosed in the cardiac imaging unit of a Spanish tertiary hospital. Results: 37 patients with severe TR induced by lead/electrode interference formed our study group. TR was predominantly severe (68%), followed by massive (21%) and torrential (11%). The leaflet most affected by the interference was the septal. 58% of the sample presented severe dilatation of the right atrium (RA) (mean RA area 28cm 2 ). Mean tricuspid annulus measurement was 42mm. The usual parameters for quantifying RV systolic function were on average within the normal range (TAPSE mean 19mm, S' wave 10mm, FAC 41%), while global RV strain (RVGLS -15%) and free wall strain (RVFWLS -19%) were found reduced. An incipient degree of ventricular/pulmonary arterial uncoupling was evident (mean TAPSE/PSAP 0.34, SGLVD/PSAP 0.27%/mmHg). Conclusions: Our patients with CIED-induced severe TR are characterized by a heterogeneous phenotype with a high prevalence of severe RA and tricuspid annulus dilatation. RVGLS, RVFWLS, and arterial ventricular coupling were the most sensitive parameters for early assessment of RV systolic dysfunction. (Copyright © 2024 Elsevier España, S.L.U. All rights reserved.)
