  1. *Moderate left atrial enlargement compared with normal left atrial size.
  2. Compared to none/physiological valvular regurgitation/stenosis. N describes the number of observations included in the analysis. n describes the number of pregnancies affected by the condition. Bold text indicates statistical significance (p < 0.05).
  3. DCM Dilated cardiomyopathy, C.I. Confidence interval, LVM Left ventricular mass, LVMi LVM indexed to body surface area, RWT Relative wall thickness, E/A Early to late diastolic filling ratio, E/E’ Early diastolic filling to early diastolic mitral annular velocity ratio, LA Left atrium, TAPSE Tricuspid annular plane systolic excursion.
