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.
Background:
Care of children with functionally univentricular hearts is resource-intensive.
Objectives:
To analyse pregnancy and early post-natal outcomes of fetuses with functionally univentricular hearts in the setting of a low–middle-income country.
Methods:
A retrospective study was conducted during the period of January 2008–October 2019. Study variables analysed included gestational age at diagnosis, maternal and fetal comorbidities and cardiac diagnosis including morphologic type of single ventricle. Outcomes analysed included pregnancy outcomes, type of post-natal care and survival status on the last follow-up.
Results:
A total of 504 fetuses were included. Mean maternal age was 27.5 ± 4.8 years and mean gestational age at diagnosis was 25.6 ± 5.7 weeks. Pregnancy outcomes included non-continued pregnancies (54%), live births (42.7%) and loss to follow-up (3.3%). Gestational age at diagnosis was the only factor that impacted pregnancy outcomes (non-continued pregnancies 22.5 ± 3.5 vs. live births 29.7 ± 5.7 weeks; p < 0.001). Of the 215 live births, intention-to-treat was reported in 119 (55.3%) cases; of these 103 (86.6%) underwent cardiac procedures. Seventy-nine patients (36.7%) opted for comfort care. On follow-up (median 10 (1–120) months), 106 patients (21%) were alive. Parental choice of intention-to-.treat or comfort care was the only factor that impacted survival on follow-up.
Conclusions:
Prenatal diagnosis of functionally univentricular hearts was associated with overall low survival status on follow-up due to parental decisions on not to continue pregnancy or non-intention-to-treat after birth. Early detection of these complex defects by improved prenatal screening can enhance parental options and reduce resource impact in low-and-middle-income countries.
