Surgical correction in infancy to reduce mortality in transposition of the great arteries
Insights
Infants with Transposition of the Great Arteries (TGA) have improved survival with early surgical baffle correction. This surgical approach offers better outcomes than medical management or palliative procedures for TGA.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Surgery
- Neonatal Intensive Care
Background:
- Transposition of the Great Arteries (TGA) historically has a high infant mortality rate, exceeding 80% by 6 months without intervention.
- While balloon atrial septostomy (BAS) has reduced mortality, it remains over 25% by 6 months, with cumulative mortality reaching 40% by 1 year.
Purpose of the Study:
- To evaluate the efficacy of interatrial baffle correction for TGA in infants.
- To compare surgical outcomes with existing medical and palliative management strategies.
Main Methods:
- A cohort of 12 infants with TGA, averaging 3 months of age, underwent interatrial baffle correction.
- Surface-induced deep hypothermia was employed during surgery.
- Preliminary balloon atrial septostomy (BAS) was performed in cases with inadequate atrial communication.
Main Results:
- A survival rate of 83% (10 out of 12 patients) was achieved in the surgical cohort.
- Follow-up ranged from 1 month to 8 years, averaging over 4 years.
- Surgical correction demonstrated a significantly better survival rate compared to medical management.
Conclusions:
- Infant surgical correction of TGA via interatrial baffle offers a superior survival rate.
- Early surgical intervention is recommended for infants diagnosed with TGA.
Abstract:
The mortality for infants with transposition of the great arteries (TGA) prior to the introduction of medical and surgical septostomy was over 80% by 6 months of age. The mortality has fallen recently, due to balloon atrial septostomy (BAS), but still exceeds 25% by 6 months of age in major centers. The cumulative mortality rises to 40% by 1 year of age with or without additional surgical atrial septectomy. In our center, 12 patients with an average age of 3 months were operated on for interatrial baffle correction of their TGA under surface-induced deep hypothermia. BAS had been done preliminarily in those patients without an adequate atrial communication. Ten of these 12 patients (83%) survived. These patients have been followed up from one month to eight years with an average follow-up of over four years. Surgical correction during infancy offers a better survival rate for infants with TGA than does medical management, with or without palliative surgery.
