Repair of left atrial abnormalities in children by the superior approach
Insights
This study highlights a superior surgical approach through the left atrium
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
Background:
- Congenital heart defects often require complex surgical interventions.
- Accessing intra-atrial cardiac structures in pediatric patients can be challenging.
Purpose of the Study:
- To evaluate the efficacy and safety of a superior approach via the left atrium dome for repairing cardiac lesions in children.
- To assess surgical exposure, complications, and long-term outcomes.
Main Methods:
- Surgical repair of left atrial cardiac lesions in 15 pediatric patients (3 months to 17 years).
- Utilized a superior approach through the dome of the left atrium.
- Monitored for surgical complications, arrhythmias, and long-term rhythm status.
Main Results:
- Excellent exposure of intra-atrial structures was achieved.
- No significant injury to adjacent cardiac structures or major hemorrhage from the suture line occurred.
- All survivors achieved sinus rhythm, with one developing atrial flutter post-operatively.
Conclusions:
- The superior approach through the left atrium dome is a safe and effective method for pediatric cardiac lesion repair.
- This technique offers excellent surgical visualization and minimizes complications.
- Recommended for pediatric cardiac surgery involving left atrial structures.
Abstract:
We have used the superior approach through the dome of the left atrium to repair cardiac lesions in the left atrium in 15 children ranging from 3 months to 17 years old. The single hospital death occurred in a 16-month-old infant with levo (L) transposition of the great arteries, Ebstein's malformation of the left atrioventricular valve, and ventricular septal defect. Exposure of the intraatrial structures was excellent, injury to adjacent cardiac structures did not occur, and hemorrhage from the left atrial suture line was not a problem. Though a few transient arrhythmias were seen, all survivors are in sinus rhythm without evidence of sick sinus syndrome, except 1 patient in whom atrial flutter associated with cardiomyopathy developed 1 year after operation. The excellent surgical exposure obtained of the interior of the left atrium and the absence of important complications related to the incision cause us to recommend this approach in children.
