[Aortic coarctation and associated abnormalities in the first year of life. Echocardiographic diagnosis]
Insights
Echocardiography reliably diagnoses aortic coarctation in infants, identifying associated heart defects like patent ductus arteriosus. This study supports surgical intervention for neonates and infants with coarctation of the aorta.
Area of Science:
- Pediatric Cardiology
- Medical Imaging
- Congenital Heart Disease
Context:
- Aortic coarctation is a critical congenital heart defect affecting infants.
- Early diagnosis and management are crucial for patient outcomes.
- Echocardiography is a primary non-invasive imaging modality.
Purpose:
- To evaluate the diagnostic reliability of cross-sectional echocardiography for aortic coarctation in infants.
- To document the prevalence of associated cardiac anomalies.
- To inform surgical decision-making regarding preoperative catheterization.
Summary:
- Thirty-eight infants with aortic coarctation were assessed using echocardiography.
- Direct visualization of coarctation was successful in 75% of cases.
- Patent ductus arteriosus (60%) and other anomalies (VSD, aortic stenosis) were frequently observed.
- Echocardiographic findings correlated well with surgical and autopsy data.
- The study discusses the implications for surgical management without preoperative catheterization.
Impact:
- Echocardiography is a highly reliable tool for diagnosing infantile aortic coarctation.
- Understanding associated anomalies aids in comprehensive patient management.
- Findings may influence current guidelines on preoperative investigations for aortic coarctation surgery.
Abstract:
Thirty-eight cases of "Aortic Coarctation Syndrome" presenting in the first year of life (66% under 3 months of age) were studied with cross-sectional echocardiography. Direct imaging of the coarctation was achieved in 75% of cases. Patent ductus arteriosus was present in 60% (80% before three months). Associated anomalies were present in 63%; VSD 29%, Aortic stenosis 16%, Mitral stenosis 16%, AV Canal 5%, Taussig Bing type of DORV 5%, Corrected transposition with VSD 3%, Ebstein anomaly 3%, Univentricular A-V connection 3%. The results were compared with angiographic and/or surgical and/or autoptic findings. The echocardiographic diagnosis proved to be very reliable in most cases. The policy of sending to surgery most neonates and infants with coarctation of the aorta without preoperative catheterization is discussed.
