Echocardiography derived pulmonary artery capacitance and right ventricular outflow velocity time integral on first day of life can predict survival in congenital diaphragmatic hernia

CDH survivors showed higher RVOT VTI (12.3 ± 3 ml vs 9 ± 3.1 ml), and higher PAC (0.3 ± 0,2 ml3 × mm Hg− 1 versus 0.18 ± 0.07 m3 × mm Hg− 1). Cronbach's alpha for intra-rater reliability was 0.82 for PAC and 0.98 for RVOT VTI and for inter-rater reliability was 0.74 and 0.89 consecutively. RVOT VTI of value > 10.5 ml and PAC of value > 0.24 ml3 × mm Hg− 1 differentiated CDH survivors with area under curve (AUC) 0.78(p = 0.02) and AUC 0.89(p = 0.002) consecutively with sensitivity and specificity for both > 70%. Proportional Hazard analysis showed PAC < 0.24 has a mortality risk ratio of 25.8 versus 4.36 for RVOT VTI < 10.5. First 24 h echo derived (PAC) and (RVOT VTI) can predict survivors in congenital diaphragmatic hernia patients.
