Refluxo Mitral Funcional: Vale mais a mecânica que o ventrículo

A wide range of ERO (15±14 mm², 0 to 87 mm²) was observed, unrelated to ejection fraction (P=0.32)

Conclusions

FMR is a frequent complication of LVD but displays a wide range of degree. Higher ERO of FMR is associated with the loss of annular function and most strongly with excess mitral valvular tenting, which is determined by the degree of local LV remodeling (apical and posterior displacement of papillary muscle), independent of global LV remodeling. These new quantitative observations should help define new approaches to FMR complicating LVD.
