Figure 8: Course of tricuspid annular plane systolic excursion (TAPSE) values in patients with pulmonary artery hypertension (PAH), pulmonary stenosis (PS), and tetralogy of Fallot (TOF) from mean reference values versus increasing time period. The TAPSE value data points for PAH, PS, and TOF patients are given as yellow oblique squares, green squares, and purple triangles, respectively. The interpolated mean values of control group are given as the black thin line. The -2 standard deviation line (-2SD) of the control group measurements is given as a grey dashed line. The difference of mean TAPSE values from mean reference values is expressed in centimetre (cm). |
