Insights
Angiocardiography can effectively diagnose double outlet right ventricle defects in children. Accurate localization requires assessing the defect
Area of Science:
- Pediatric Cardiology
- Diagnostic Imaging
- Congenital Heart Disease
Background:
- Double outlet right ventricle (DORV) is a complex congenital heart defect.
- Accurate localization of DORV is crucial for effective treatment planning.
- Previous diagnostic methods may have limitations in precise defect identification.
Purpose of the Study:
- To evaluate the efficacy of angiocardiography in diagnosing and localizing double outlet right ventricle in pediatric patients.
- To determine the key angiocardiographic features for accurate defect localization.
- To establish the role of ventriculography in diagnosing associated ventricular septal defects.
Main Methods:
- Retrospective analysis of pediatric patients diagnosed with double outlet right ventricle.
- Performance of angiocardiography, including standard and axial projections for ventriculography.
- Assessment of the spatial relationship between the ventricular septal defect, conus septum, and great arteries.
Main Results:
- Angiocardiography demonstrated satisfactory localization of the double outlet right ventricle defect.
- The interaction between the defect and the conus septum was identified as critical for localization.
- Right and left ventriculography were essential for diagnosing coexisting ventricular septal defects.
Conclusions:
- Angiocardiography is a reliable imaging modality for diagnosing and localizing double outlet right ventricle in children.
- Detailed analysis of the conus septum and great artery origins improves diagnostic accuracy.
- Ventriculography is indispensable for the complete diagnosis of associated ventricular septal defects in DORV.
Abstract:
Children with double outlet right ventricle, aged 3 months to 23.5 years, were examined to assess the possibility of angiocardiographic diagnosis of defect localization. It was found angiocardiography allows satisfactory localization of the defect in question. To be able localize the defect, it is critical to determine the interaction between the defect and the conus septum, and the origin of large arteries. To establish the diagnosis of ventricular septal defect, right and left ventriculography in standard and axial projections must be performed.
