Key result
Percutaneous mitral valve repair reduced regurgitant volume from 84.1 mL to 35.6 mL, as assessed by 3D transesophageal echocardiography.
Why the study?
Does percutaneous mitral valve repair (MitraClip) reduce mitral regurgitant volume and improve cardiac remodeling in high-risk surgical patients with functional mitral regurgitation?
Population
39 high-risk surgical patients with moderate to severe functional mitral valve regurgitation
Comparison
Percutaneous mitral valve repair using the… vs Pre-intervention baseline (before PMVR)
Design
Cohort
Follow-up
6 months

3D TEE may aid post-PMVR assessment in high-risk patients; leaves open validation of MR grading for double-orifice valves.
Observational (n=39)
Does percutaneous mitral valve repair (MitraClip) reduce mitral regurgitant volume and improve cardiac remodeling in high-risk surgical patients with functional mitral regurgitation?
Absolute Event Rate: 35.6% vs 84.1%
3D TEE demonstrates significant reduction of regurgitant volume and allows improved understanding of morphological changes after percutaneous mitral valve repair.
Altiok et al. (2012) conducted an observational in moderate to severe functional mitral valve regurgitation (n=39). Percutaneous mitral valve repair (MitraClip) vs. Preintervention (baseline) was evaluated on Mitral valve regurgitant volume. Percutaneous mitral valve repair reduced regurgitant volume from 84.1 mL to 35.6 mL, as assessed by 3D transesophageal echocardiography.
