Selective aortic root angiography in the hypoplastic left heart syndrome
European Journal of Cardiology
|March 1, 1976
Summary
Selective aortic root angiography revealed wide variations in aortic root size in patients with hypoplastic left heart syndrome, crucial for accurate echocardiographic diagnosis and differentiating from other neonatal heart conditions.
Area of Science:
- Pediatric Cardiology
- Diagnostic Imaging
- Congenital Heart Disease
Background:
- Hypoplastic left heart syndrome (HLHS) is a severe congenital heart defect.
- Accurate diagnosis is critical for management and improving outcomes.
- Echocardiography is a primary diagnostic tool, but challenges exist.
Purpose of the Study:
- To evaluate the utility of selective aortic root angiography in patients with suspected HLHS.
- To correlate angiographic findings with echocardiography and necropsy results.
- To characterize the variability of the aortic root and ascending aorta in HLHS.
Main Methods:
- Selective aortic root angiography was performed in 18 patients diagnosed with HLHS.
- Angiographic findings were compared with echocardiographic data and necropsy findings.
- Measurements of the aortic root and ascending aorta dimensions were analyzed.
Main Results:
- Angiography confirmed aortic valve atresia and severe left heart hypoplasia in all patients.
- Significant variations in aortic root and ascending aorta dimensions were observed.
- In some cases with aortic atresia, aortic root and sinus of Valsalva dimensions were nearly normal.
- A coronary-cameral fistula was identified in one patient.
Conclusions:
- The aortic root size can be near normal in some HLHS patients, impacting echocardiographic diagnosis.
- Angiography provides precise anatomical detail for HLHS diagnosis and differential diagnosis.
- Understanding aortic root variability is essential for accurate echocardiographic interpretation in neonatal heart failure.
