Summary
This case report details a rare double-outlet right ventricle diagnosis in a newborn. Surgical intervention, including a shunt and atrial septectomy, led to good clinical condition.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease
- Neonatal Medicine
Background:
- Double-outlet right ventricle (DORV) with an intact ventricular septum is a rare congenital heart malformation.
- This specific subtype presents unique diagnostic and management challenges in neonates.
Observation:
- A 3-day-old female newborn was diagnosed with DORV and intact ventricular septum.
- Associated anomalies included an inadequate atrial septal defect, mitral valve hypoplasia, and left ventricular hypoplasia.
- The left ventricle's sole outlet was determined to be through the atrial septal defect.
Findings:
- Diagnosis was confirmed using two-dimensional echocardiography and angiocardiography.
- Initial management involved balloon atrial septostomy.
- The patient subsequently required a modified Blalock-Taussig shunt and surgical atrial septectomy at one month of age.
Implications:
- This case highlights the importance of early and accurate diagnosis of complex congenital heart defects.
- Timely surgical interventions, including palliative shunting and septal procedures, can improve clinical outcomes in DORV.
- Further research into long-term outcomes for this rare condition is warranted.
