PVRi, pulmonary vascular resistance index; RV-FAC-3C, right ventricle fractional area changes in three chamber view; TAPSE, tricuspid annular peak excursion; LV-EF, left ventricle ejection fraction. Values are presented as numbers and percentages. P values are the results of general linear model repeated measures.
*P value (time) represents the significance of changing values over the two different time points.
#
P value (group) represents the significance of the difference between the two groups.
