Many parents worry about brain health when their child is born with a heart defect. A new analysis looked at over 5,000 fetuses and children from birth to age 21. The team used magnetic resonance imaging to check for structural brain changes. They found that 23.1 percent of cases showed these issues during the prenatal period. The numbers grew higher after birth but before surgery, reaching 36.7 percent. After the operation, the rate climbed to 50.3 percent. This rise suggests the brain changes become more visible or common as the child grows and undergoes treatment. The study included children with isolated heart defects, meaning no other syndromes were present. The researchers noted that different MRI machines and detection limits might affect the results. They also questioned why doctors order these scans so often. These findings matter because they highlight a need to understand brain risks alongside heart repairs. Families should know that these brain changes are not rare in this group.

Key Takeaway
Note rising structural cerebral abnormality prevalence from 23.1% prenatally to 50.3% postoperatively in isolated CHD.
This systematic review and meta-analysis assesses the prevalence of structural cerebral abnormalities on magnetic resonance imaging in fetuses from 24 weeks gestation to birth and children from birth to 21 years with isolated nonsyndromic congenital heart disease. The analysis included 521, 1895, and 2443 fetuses and children for prenatal, postnatal-preoperative, and postoperative analyses, respectively.
The primary outcome measured the prevalence of structural cerebral abnormalities. Results indicated a prevalence of 23.1% for the prenatal period. In the postnatal-preoperative period, the prevalence was 36.7%. Following surgery, the prevalence increased to 50.3% for the postoperative period. Absolute numbers were not reported for these outcomes.
The authors identified several limitations affecting the interpretation of these findings. These include variations in MRI strength, differences in postnatal versus fetal MRI detection capacity, and the underlying rationale for neuroimaging. Safety data and adverse events were not reported. The study does not establish causality between the heart condition or surgical intervention and the observed abnormalities.

CONTEXT: Children with congenital heart disease (CHD) are at risk of cerebral abnormalities. Current evidence is limited by small sample sizes, single-center cohorts, and single time points.
OBJECTIVE: Conduct a systematic review and meta-analysis to determine the prevalence of structural cerebral abnormalities on magnetic resonance imaging (MRI) in children with CHD during prenatal, postnatal-preoperative, and postoperative periods.
DATA SOURCES: Five electronic databases from inception to August 4, 2025.
STUDY SELECTION: Studies published in English in peer-reviewed journals that met the following criteria: 1) samples comprised fetuses from 24 weeks gestation to birth or children from birth to 21 years, with 2) isolated (nonsyndromic) CHD with or without surgical intervention within the first year of life, and 3) reported structural cerebral abnormalities on MRI, during 4) prenatal, postnatal-preoperative, or postoperative period.
DATA EXTRACTION: Data were extracted independently by 2 authors. Data were synthesized using random-effects modeling to determine pooled estimates.
RESULTS: Overall, 125 studies met the inclusion criteria. Sample size included 521, 1895, and 2443 fetuses and children with CHD for prenatal, postnatal-preoperative, and postoperative analyses, respectively, ensuring sample independence. The pooled overall prevalence of structural cerebral abnormalities was 23.1%, 36.7%, and 50.3% for prenatal, postnatal-preoperative, and postoperative periods, respectively.
LIMITATIONS: Variations in MRI strength, postnatal vs fetal MRI detection capacity, and the underlying rationale for neuroimaging.
CONCLUSIONS: Structural cerebral abnormalities are prevalent in a considerable number of fetuses and children with CHD. A further increase is evident postoperatively, indicating the potential adverse impact of surgical intervention and postoperative care on brain outcomes.
