Summary
Tricuspid atresia (TA) outcomes are significantly impacted by pulmonary artery anatomy. Early referral and surgical intervention improve survival rates in children with this cyanotic heart defect.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease
- Cardiac Surgery
Background:
- Tricuspid atresia (TA) is a common cyanotic congenital heart defect with high early mortality.
- Unfavorable anatomy, particularly hypoplastic pulmonary arteries, contributes to poor outcomes despite surgical advances.
Purpose of the Study:
- To analyze the clinical profile and outcomes of children with tricuspid atresia.
- To evaluate the effectiveness of various treatment modalities and identify factors influencing survival.
Main Methods:
- Retrospective descriptive study of 27 children with tricuspid atresia.
- Analysis of clinical presentation, electrocardiogram (ECG) findings, treatment interventions, and survival data.
Main Results:
- Eleven patients (40.7%) died, with 8 deaths occurring before surgery.
- Pulmonary artery anatomy, especially extreme hypoplasia, significantly influenced outcomes.
- Increased pulmonary blood flow was associated with better outcomes than decreased flow.
Conclusions:
- Pulmonary artery anatomy is a critical determinant of survival in tricuspid atresia.
- Early referral for palliation and timely surgical intervention are essential for improving outcomes.
- Few patients were eligible for the Fontan procedure due to pulmonary hypertension or severe pulmonary hypoplasia.
