Summary

Background:

\- Mitral regurgitation, or leaking of the mitral heart valve, is usually studied and assessed with an ultrasound test called a two-dimensional (2D) echocardiogram. While this test has proved very useful, technological improvements have helped researchers develop ways to study the heart valves using imaging with three-dimensional (3D) capabilities. In addition, recently developed magnetic resonance imaging (MRI) techniques may be able to provide better information about the causes and severity of the leak. Researchers are interested in testing these new techniques to determine their usefulness for patients with mitral regurgitation.

Objectives:

\- To evaluate newer methods of studying mitral regurgitation severity using real-time 3D echocardiography (RT3DE) and cardiac magnetic resonance imaging (CMRI).

Eligibility:

\- Individuals at least 21 years of age who have been diagnosed with more than mild mitral regurgitation.

Design:

* Participants will have two procedures as part of this study: an echocardiogram and an MRI scan.
* For the echocardiogram, participants will have an ultrasound scan with a special kind of probe. Participants may also receive an injection of a contrast agent to provide a better image of the heart on the scan. The scan will take approximately 1 hour to complete.
* For the MRI scan, participants will have a standard MRI with special pads placed on the chest to provide better imaging of the heart. The scan will usually take between 45 and 90 minutes to complete.
