The purpose of this research is to assess the severity of tricuspid regurgitation (a disorder in which the tricuspid valve in the heart does not close tight enough) using cardiac magnetic resonance imaging (MRI).

40 patients with moderate or more TR on echocardiography will undergo CMR/MRE with contrast to assess TR severity, and the associated extra-valvular cardiac and liver abnormalities as shown in the flow diagram below. Patients will continue their clinical management by their primary physicians as per the standards of care. 1-year follow up will be conducted via phone to inquire about patient's vital status (dead/alive), symptoms and hospitalizations.

Inclusion Criteria:

• Moderate or more tricuspid regurgitation

Exclusion Criteria:

1. Prior tricuspid valve prosthesis
2. Pacemaker/defibrillator that would impede MRI imaging
3. Planned tricuspid valve surgery
4. Primary liver pathology
