Complete congenital heart block: a review and case study
1Cardinal Glennon Children's Hospital, St. Louis, MO 63104, USA.
Insights
Complete congenital heart block (CCHB) is a rare newborn condition often caused by maternal autoantibodies or heart abnormalities. Early recognition and nursing care are vital for managing infants with CCHB and their families.
Area of Science:
- Neonatal cardiology
- Pediatric immunology
Background:
- Complete congenital heart block (CCHB) is a rare but serious neonatal condition.
- It presents significant risks for morbidity and mortality in newborns.
Observation:
- CCHB typically results from maternal autoantibodies crossing the placenta to affect the fetal heart.
- Alternatively, it can be linked to congenital structural heart defects.
Findings:
- Infants with CCHB face risks of reduced cardiac output and congestive heart failure.
- Many affected infants necessitate cardiac pacemaker implantation.
Implications:
- Healthcare professionals, particularly nurses, require a thorough understanding of CCHB.
- Specialized knowledge is crucial for addressing the unique challenges faced by infants and families affected by CCHB.
Abstract:
Complete congenital heart block (CCHB) is a rare disease of the newborn that carries significant morbidity and mortality. It generally occurs as a result of the presence of maternal autoantibodies that are transferred to the fetus and affect the fetal heart, or it may be associated with a congenital structural abnormality of the heart. Infants with CCHB are at risk for diminished cardiac output and the subsequent development of congestive heart failure. Many infants require the placement of a cardiac pacemaker. It is essential that the nurse caring for these infants have a good understanding of the disease process and be familiar with the unique problems that these infants and their families may encounter.
