Fig. 2 — Patterns of tricuspid annular plane systolic excursion (TAPSE) during pregnancy in women with elevated first-trimester N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels (black line, n = 12) and women with normal first-trimester NT-proBNP levels (grey line, n = 92). A significant difference in the pattern of TAPSE was found between women with elevated NT-proBNP and those with normal NT-proBNP (p = 0.019). TAPSE increased from 10–14 weeks to 20–24 weeks in women with normal NT-proBNP. Only in women with elevated NT-proBNP did TAPSE significantly decrease from 20–24 weeks’ to 30–34 weeks’ gestation
