Transcatheter Edge-to-Edge Repair for Severe Isolated Tricuspid Regurgitation: The Tri.Fr Randomized Clinical Trial.

Importance: Correction of tricuspid regurgitation using tricuspid transcatheter edge-to-edge repair (T-TEER) in addition to guideline-directed optimized medical therapy (OMT) may improve clinical outcomes.

Objective: To evaluate the efficacy of T-TEER + OMT vs OMT alone in patients with severe, symptomatic tricuspid regurgitation.

Design, Setting, And Participants: Investigator-initiated, prospective, randomized (1:1) trial evaluating T-TEER + OMT vs OMT alone in adult patients with severe, symptomatic tricuspid regurgitation.

Accuracy of point of care coagulometers compared to reference laboratory measurements in patients on oral anticoagulation therapy.

Background: Vitamin K antagonists (VKA) are widely prescribed throughout the world. Patients on VKA therapy require international normalized ratio (INR) monitoring of venous blood to ensure the response remains within the therapeutic window. Point-of-care devices (POC-INR) can safely and easily monitor VKA efficacy but need to be evaluated in practice.
