LA = left atrium; LVEDD = left ventricular end diastolic diameter; LVESD = left ventricular end systolic diameter; FS = fractional shortening; LVEDV = left ventricular end diastolic volume
LVESV = left ventricular end systolic volume; EF = ejection fraction
MR = mitral regurgitation; sPAP = systolic pulmonary artery pressure
* baseline vs one month
