Data were expressed as mean ± standard deviation. OI, osteogenesis imperfecta; PAO, proximal ascending aorta; MPA, main pulmonary artery; LAD, left atrial anteroposterior dimension; LVEDd, left ventricular end-diastolic dimension; RVEDd, right ventricular end-diastolic dimension; IVST, interventricular septal wall thickness; LVPWT, left ventricular posterior wall thickness; LVM: left ventricular mass; HR, heart rate; LVEF, left ventricular ejection fraction. Data were expressed as mean ± SD.
