Primary tricuspid regurgitation (TR) is an underrecognized valve disease characterized by structural abnormalities of the tricuspid valve (TV) apparatus, including leaflet prolapse, flail, rheumatic degeneration, carcinoid involvement and congenital malformations such as Ebstein’s anomaly. Historically neglected and often misclassified as functional, primary TR has recently gained attention due to advances in multimodality imaging and increased awareness of its pathophysiological complexity and adverse outcomes. A major challenge that remains is the accurate diagnosis of primary TR, as well as the optimal timing for intervention, particularly in asymptomatic patients. While surgical repair or replacement has been the traditional approach, recent developments in transcatheter therapies, such as tricuspid edge-to-edge repair, have broadened the therapeutic landscape for patients considered at high surgical risk. In this context, personalized medicine has emerged as a central paradigm in the management of this valvular disease. Tailored therapeutic decisions should include anatomical, functional, and clinical parameters, as well as patient-specific risk factors such as age and comorbidities. Advanced imaging modalities, including 3D echocardiography and cardiac magnetic resonance, are essential for guiding this individualized approach. This review summarizes the current understanding of the etiology, pathophysiology, diagnostic tools, and treatment strategies for primary TR, highlighting the critical role of personalized treatment pathways in optimizing clinical outcomes.
