Summary
A double switch operation improved tricuspid regurgitation in a 2-month-old infant with complex congenital heart disease. This surgical approach offers advantages for systemic atrioventricular valve function in young patients.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Surgery
- Cardiovascular Physiology
Background:
- Congenitally corrected transposition of the great arteries (ccTGA) often presents with complex intracardiac anomalies.
- Ebstein's malformation with severe tricuspid regurgitation poses significant challenges in infants.
- Combined defects like ventricular septal defect (VSD) and pulmonary hypertension (PHT) complicate ccTGA management.
Observation:
- A 2-month-old infant with ccTGA, Ebstein's malformation, VSD, PHT, and congestive heart failure underwent surgical intervention.
- The patient received a combined Senning and arterial switch operation (double switch procedure).
Findings:
- The double switch operation resulted in improved tricuspid regurgitation.
- The surgical intervention addressed the complex congenital heart defects effectively.
Implications:
- The double switch operation demonstrates efficacy in managing complex ccTGA with severe tricuspid regurgitation in infants.
- This approach enhances systemic atrioventricular valve function, particularly when primary valve repair outcomes are suboptimal.
- It offers a promising surgical strategy for improving long-term outcomes in neonates and young infants with critical congenital heart disease.
