Insights
Right posterolateral thoracotomy offers a cosmetic alternative to median sternotomy for pediatric open heart surgery. This approach is effective for isolated congenital heart defects, yielding excellent long-term outcomes and minimal scarring.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Thoracic Surgery
Context:
- Median sternotomy for congenital heart disease in children can lead to aesthetic concerns.
- Minimally invasive surgical approaches are increasingly sought for pediatric cardiac procedures.
Purpose:
- To evaluate the safety and efficacy of right posterolateral thoracotomy for isolated congenital heart disease in pediatric patients.
- To assess the cosmetic outcomes and long-term results of this surgical approach.
Summary:
- A right posterolateral thoracotomy was performed in 146 children (5 months to 14 years) for isolated congenital heart disease, predominantly atrial septal defects (96%).
- The study reported one death and minor complications in 15 cases, with one reoperation for a residual shunt. Survivors remain asymptomatic with excellent cosmetic results after a 2.6-year follow-up.
- Accurate anatomical diagnosis is crucial, and left superior vena cava draining into the coronary sinus is a contraindication.
Impact:
- Right posterolateral thoracotomy is a viable and preferred approach for specific pediatric congenital heart defects, particularly ostium secundum atrial septal defects.
- This technique provides superior cosmetic results compared to sternotomy, improving patient satisfaction.
- The findings support the adoption of this minimally invasive technique for suitable pediatric cardiac surgical cases.
Abstract:
In order to avoid the aesthetic prejudice of median sternotomy in young children undergoing open heart surgery for isolated congenital heart disease, a right posterolateral thoracotomy was performed in 146 children aged 5 months to 14 years. The large majority (140/146, 96%) were atrial septal defects: 130 ostium secundum, 5 sinus venosus, 1 low septal defect and 4 ostium primum (partial endocardial cushion defect). Six children had isolated perimembranous ventricular septal defects. One patient died of a probable lesional pulmonary oedema. Minor complications were observed in 15 cases and one had to be reoperated for a residual shunt. With an average follow-up of 2.6 years, all survivors are asymptomatic. The scar is normal, without cheloid or thoracic deformation, invisible to the patient when he looks in a mirror. The use of this approach requires a very accurate anatomical diagnosis, especially with regards to systemic and pulmonary drainage. The presence of a left superior vena cava draining into the coronary sinus is a contra-indication. The right posterolateral thoracotomy is now the approach of choice in its standard indication, the repair of ostium secundum atrial septal defects with large shunts, in young girls under 10 years of age.
