Fig. 4. Critical Closing Pressure and Diastolic Closing Margin by PDA Size.

Fig. 4.

a. Critical closing pressure (CrCP) was not different according to PDA size. CrCP was 19.7 ± 5.8, 17.9 ± 4.6, and 17.4 ± 6.3 mmHg in the no/small, moderate, and large PDA groups, respectively. b. Diastolic closing margin (DCM) was not different according to PDA size. However, the large PDA group showed a trend of decreased DCM, although not significant. DCM was 6.2 ± 2.4, 6.0 ± 2.2, and 4.8 ± 2.1 mmHg in the no/small, moderate, and large PDA groups, respectively.
