Values are mean ± SD or %.

BSA = body surface area; EF = ejection fraction; ERO = effective regurgitant orifice; LAD = left atrium diameter; LV = left ventricular; LVEDD = left ventricular end-diastolic diameter; LVESD = left ventricular end-systolic diameter; MR = mitral regurgitation; RVol = regurgitant volume; SPAP = systolic pulmonary artery pressure.

  • LVEDD between 100% and 120% of upper limit of normal for the individual.

  • LVEDD >120% of upper limit of normal.
