Results are presented as mean ± SD.
LVEDD: left ventricular end-diastolic diameter; LVESD: left ventricular end-systolic diameter; IVSd: interventricular thickness (diastole); PWd: left ventricular posterior wall diameter (diastole); EF: ejection fraction; FS: fraction of shortening; RV: right ventricular diameter; FAC RV: right ventricular fractional area change.
