Data are expressed as means ± SEM for continuous variables and absolute (and relative) frequencies for categorical variables; P<0.05 was considered to be statistically significant. AR Moderate to severe aortic regurgitation; AS Moderate to severe aortic stenosis; LVEF Left ventricular ejection fraction; MR Mitral-valve regurgitation expressed as mean grade assessed by a semi-quantitative method (1+ to 4+); MS Moderate to severe mitral stenosis; PH Signs of pulmonary hypertension;
