A Randomized Clinical Trial of Metoprolol in Participants With Mitral Regurgitation.

• Status: Completed
• Trial end date: 2007-07-01
• Target enrollment: 0
• Participant gender: All

Summary

Mitral valve regurgitation (leakage of the mitral valve of the heart) is frequent and currently there is no specific medical therapy. Mitral regurgitation is a slowly progressive disease that frequently requires surgical treatment. This randomized clinical trial will use Metoprolol, a common beta-blocker medication, to determine if medical treatment impacts mitral valve disease progression.

• Phase: Phase 4
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Mayo Clinic
• Collaborator: AstraZeneca

Criteria

Inclusion criteria: Patients a) 21 years old or older, with b) MR observed with color flow imaging, c) due to organic mitral valve disease demonstrated by Echocardiography (not normal valve as in functional or ischemic MR), c) isolated (no valve disease other than functional tricuspid regurgitation by Doppler-Echocardiography), d) pure (no mitral stenosis by Doppler-Echocardiography), e) quantifiable by Doppler-Echocardiography, f) of degree * moderate, defined as RVol * 30 mL/beat, g) occurring on native valves, h) with echocardiographic imaging allowing assessment of LA and LV, and i) asymptomatic (or mildly symptomatic but not considered as candidates for immediate surgery by their attending physician).
