Figure 1 Score Prediction of Post-Natal Circulation Before 23 Weeks’ Gestation
Score prediction before 23 weeks’ gestation using a cutoff of pulmonary valve (PV) z-scores >–1 and tricuspid valve (TV) z-scores >–3.4 to predict a biventricular (BV) rather than univentricular (UV) post-natal surgical pathway. Fetus 6 was seen twice, at 15 + 5 and 19 + 5 weeks’ gestation when the z-scores (6') were worse. Normal z-score ranges are between +2 and –2. Circles = score of 0; squares = score of 1.
