Values for continuous variables are expressed as mean ± standard deviation. LAESD: left atrial end-systolic diameter; LVESD: left ventricular end-systolic diameter; LVEDD: left ventricular end-diastolic diameter; LVEF: left ventricular ejection fraction; MPG: mean pressure gradient; MR: mitral regurgitation
