BACKGROUND

Prenatal diagnosis and planned peri-partum care is an unexplored concept for care of neonates with critical CHDs in low-middle-income countries.

OBJECTIVE

To report the impact of prenatal diagnosis on pre-operative status in neonates with critical CHD.

METHODS

Prospective observational study (January 2017-June 2018) in tertiary paediatric cardiac facility in Kerala, India. Neonates (<28 days) with critical CHDs needing cardiac interventions were included. Pre-term infants (<35 weeks) and those without intention to treat were excluded. Patients were grouped into those with prenatal diagnosis and diagnosis after birth. Main outcome measure was pre-operative clinical status.

RESULTS

Total 119 neonates included; 39 (32.8%) had prenatal diagnosis. Eighty infants (67%) underwent surgery while 32 (27%) needed catheter-based interventions. Pre-operative status was significantly better in prenatal group; California modification of transport risk index of physiological stability (Ca-TRIPS) score: median 6 (0-42) versus 8 (0-64); p < 0.001; pre-operative assessment of cardiac and haemodynamic status (PRACHS) score: median 1 (0-4) versus 3 (0-10), p < 0.001. Age at cardiac procedure was earlier in prenatal group (median 5 (1-26) versus 7 (1-43) days; p = 0.02). Mortality occurred in 12 patients (10%), with 3 post-operative deaths (2.5%). Pre-operative mortality was higher in postnatal group (10% versus 2.6%; p = 0.2) of which seven (6%) died due to suboptimal pre-operative status precluding surgery.

CONCLUSION

Prenatal diagnosis and planned peri-partum care had a significant impact on the pre-operative status in neonates with critical CHD in a low-resource setting.
