Transatrial repair of ventricular septal defects with reference to their anatomic classification
Insights
This study on pediatric ventricular septal defect (VSD) surgery found that the right atrial approach, while achieving repair in 72% of cases, resulted in a 24% incidence of right bundle branch block. The right atrial route is recommended for VSD repair.
Area of Science:
- Pediatric Cardiac Surgery
- Congenital Heart Defects
Background:
- Ventricular septal defect (VSD) is a common congenital heart anomaly requiring surgical intervention.
- Surgical repair aims to close the defect and improve cardiac function.
Purpose of the Study:
- To evaluate the outcomes of surgical VSD repair using a right atrial approach in pediatric patients.
- To assess the efficacy and safety of this surgical technique.
Main Methods:
- A consecutive series of 50 children underwent elective VSD repair.
- Atriotomy was routinely performed, with attempts to repair the defect through the tricuspid valve.
Main Results:
- Successful repair was achieved in 72% of patients.
- A 24% incidence of right bundle branch block was observed.
- All patients experienced symptomatic improvement post-operation.
- The study reported a 4% mortality rate.
Conclusions:
- The right atrial approach is considered a preferable primary surgical strategy for VSD repair in children.
- This method demonstrated favorable outcomes with no identified disadvantages.
Abstract:
A consecutive series of 50 children undergoing elective operations for ventricular septal defect (VSD) is presented. Atriotomy was performed routinely. Repair of the defect through the tricuspid valve was attempted in all cases and achieved in 72 percent. There was a 24 percent incidence of right bundle branch block. All patients improved symptomatically after the operation. The mortality rate was 4 percent. The right atrial route is considered to be preferable as a primary approach and has no disadvantages.
