Conditions:
Tricuspid Valve Regurgitation, Non-rheumatic
Mitral Valve Regurgitation
Eligibility:
All Genders
Brief Summary
The purpose of this pilot study is to evaluate mitral (left atrioventricular valve) and tricuspid (right atrioventricular valve (AVV)) regurgitation using cardiac magnetic resonance imaging (CMR) as t...
Detailed Description
BACKGROUND, SIGNIFICANCE, AND RATIONALE (including preliminary studies and any results) The integrity of the two atrioventricular valves (AVV)(i.e., the mitral and tricuspid valve) plays an important ...
Eligibility Criteria
Inclusion
- Audible AV valve regurgitation on clinical exam, as noted by most recent clinic note.
- Clinically indicated CMR study scheduled and have had an echocardiogram in the last 6 months
Exclusion
- Poor quality CMR study
- Unable to complete a CMR
- Have a contraindication to CMR scan (e.g., pregnancy, pacemaker or defibrillator presence, unable to hold still within scanner for imaging)
- Common AV valve
- Corresponding semilunar valve regurgitation which precludes use of stroke volume comparison as a second means of assessing AVV regurgitation by CMR
- Intracardiac shunts which precludes use of stroke volume comparison as a second means of assessing AVV regurgitation by CMR.
