*Difference between baseline and long-term follow-up values is statistically significant; (all p-values ≤ 0.03).

LVEDD – Left ventricular end-diastolic diameter; LVESD – Left ventricular end-systolic diameter; LVEDV – Left ventricular end-diastolic volume; LVESV – Left ventricular end-systolic volume; LVEF – Left Ventricular Ejection Fraction; LA – Left atrium; MR- Mitral regurgitation; PASP – Pulmonary artery systolic pressure.
