Insights
Isolated right ventricular hypoplasia, a rare congenital heart defect, was observed in a father and son. This suggests a potential autosomal dominant inheritance pattern for this condition.
Area of Science:
- Cardiology
- Genetics
- Pediatric Medicine
Background:
- Isolated right ventricular hypoplasia is a rare congenital anomaly.
- It is often associated with atrial communications like patent foramen ovale or atrial septal defects.
Observation:
- A familial occurrence of isolated right ventricular hypoplasia with atrial septal defect was identified.
- The affected individuals were a 1-day-old male infant and his 34-year-old father.
Findings:
- The study identified isolated right ventricular hypoplasia in two related individuals.
- The presence of atrial septal defects was noted in both affected family members.
Implications:
- The findings suggest a possible autosomal dominant inheritance pattern for isolated right ventricular hypoplasia.
- This highlights the importance of genetic counseling and family screening for congenital heart anomalies.
Abstract:
Isolated right ventricular hypoplasia is a rare congenital anomaly. This condition is usually associated with a communication between the atria in the form of a patent foramen ovale or secondum atrial septal defect. We describe a familial occurrence of this rare disease. A 1-day-old male child and his 34-year-old father were found to have isolated right ventricular hypoplasia with atrial septal defect. An autosomal dominant mode of inheritance is likely for this rare congenital anomaly.
