Feasibility of time resolved magnetic resonance imaging of contrast kinetics to identify severe tricuspid valve regurgitation

Introduction: An echocardiographic parameter of severe tricuspid valve regurgitation (TR) is systolic retrograde flow in the hepatic veins. However the acoustic window using transthoracic echocardiography is not always sufficient to quantify the amount of regurgitation. Time resolved imaging of contrast kinetics (TRICKS®) is a 4-dimensional magnetic resonance (MR) angiography option with high spatial and temporal resolution. If identification of patients with severe TR by using TRICKS® angiography is feasible is not known and aim of the present study. Methods: TRICKS® angiography was performed in a 3T-MR-scanner…
