Summary
This case study presents a respirator-dependent infant with Ebstein's anomaly. Surgical intervention successfully weaned the infant from mechanical ventilation, improving pulmonary blood flow.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease
- Cardiac Surgery
Background:
- Ebstein's anomaly is a rare congenital heart defect affecting the tricuspid valve.
- Neonatal presentation often involves severe tricuspid regurgitation and pulmonary stenosis.
- Fetal echocardiography is crucial for early diagnosis and management planning.
Observation:
- An 11-day-old infant presented with respiratory failure due to Ebstein's anomaly and massive tricuspid regurgitation.
- Progressive cardiomegaly was noted on fetal echocardiography at 24 weeks' gestation.
- Mechanical ventilation was required due to restricted pulmonary blood flow.
Findings:
- Surgical repair included tricuspid valve patch closure, right atrial wall resection, and a central shunt.
- The infant was successfully weaned from mechanical ventilation on postoperative day 13.
- A subsequent cavopulmonary anastomosis at 8 months of age was performed without complications.
Implications:
- Early surgical intervention can significantly improve outcomes in neonates with severe Ebstein's anomaly.
- Multistage surgical approaches may be necessary for complex congenital heart defects.
- This case highlights the importance of timely surgical management for respirator-dependent infants with critical congenital heart disease.
