The study is focused on evaluation of the effectiveness of the Admittance Pulmonary Artery Catheter (PAC) system for assessing the right ventricular (RV) function in patients with tricuspid regurgitation (TR) prior to tricuspid valve intervention.
Patients with severe or torrential TR who are already scheduled to undergo clinically indicated tricuspid valve (TV) percutaneous replacement or clipping to reduce heart failure symptoms
Children (defined as individual <18 years of age) will be excluded from this study

Prospective
Right Heart Catheterization
DeviceA right heart catheter is placed in the pulmonary artery
Obtain Ees/Ea consistent with non-invasive literature of TAPSE/PASP: CouplingRatio_ECHO-CouplingRatio_PAC ≤ 0.2 (unitless)
We will obtain end-systolic elastance (Ees), arterial elastance (Ea) and its ratio (Ees/Ea) derived from pressure-volume loops. Ees represents RV strength of contraction, Ea represents RV afterload from the pulmonary circuit.
