Summary
This study details two cases of double outlet right ventricle with restrictive ventricular septal defects. Accurate diagnosis requires careful study of unique clinical, hemodynamic, and angiographic features for effective surgical planning.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease
- Cardiac Surgery
Background:
- Double outlet right ventricle (DORV) is a complex congenital heart defect.
- Restrictive ventricular septal defects (VSDs) present unique diagnostic and management challenges.
- Understanding associated anatomical variations is crucial for surgical outcomes.
Observation:
- Two cases of DORV with subaortic restrictive VSD, atrial situs solitus, and atrioventricular concordance were identified.
- Diagnostic modalities included electrocardiogram (EKG), chest X-rays, hemodynamic studies, and angiocardiography.
- Specific findings included left ventricular overload, left atrial enlargement, venocapillary hypertension, and left ventricular/right ventricular pressure gradients.
Findings:
- One case exhibited mitro-aortic discontinuity.
- The second case presented a double infundibulum, with the left component causing the restrictive VSD.
- These cases highlight distinct clinical, hemodynamic, and angiographic characteristics.
Implications:
- Accurate characterization of these features is essential for appropriate surgical intervention in DORV with restrictive VSD.
- This study contributes to the understanding of rare congenital heart anomalies.
- Improved diagnostic strategies can lead to better surgical planning and patient outcomes.
