[A study of relation of cardiac function and deformity degree in children with pectus excavatum]
Insights
Children with pectus excavatum often have impaired cardiac function, indicated by a low fração de ejeção (FI). Surgical correction improves both cardiac function and the thoracic index in these patients.
Area of Science:
- Pediatric Cardiology
- Thoracic Surgery
- Diagnostic Imaging
Background:
- Pectus excavatum is a congenital chest wall deformity.
- Cardiac function can be compromised in children with pectus excavatum.
- The fração de ejeção (FI) is a potential indicator of cardiac compromise.
Purpose of the Study:
- To investigate the relationship between cardiac function and pectus excavatum severity.
- To evaluate the impact of surgical correction on cardiac function and thoracic index.
- To determine if FI < 0.2 indicates damaged cardiac function in pediatric pectus excavatum patients.
Main Methods:
- 40 children with pectus excavatum were assessed.
- Patients were subgrouped based on FI (> 0.2 or < 0.2).
- Cardiac function was evaluated using M-mode echocardiography (M-ME) before and after surgery for 28 patients.
Main Results:
- Children with pectus excavatum and FI < 0.2 exhibited impaired cardiac function.
- Post-operative re-examination of 28 patients showed improved cardiac function.
- Improvement in thoracic index correlated with enhanced cardiac function after surgery.
Conclusions:
- Pectus excavatum can lead to cardiac dysfunction, particularly when FI is below 0.2.
- Surgical correction of pectus excavatum positively impacts cardiac function.
- Thoracic index improvement post-surgery is associated with better cardiac performance.
Abstract:
40 children with pectus excavatum were divided into subgroups according to the FI (> 0.2 or < 0.2) and underwent M-ME examination for their cardiac function. 28 of 40 patients had their cardiac function and thoracic index re-examined after the operation. The results showed the cardiac function of children with pectus excavatum was damaged as FI of the patients was less than 0.2 and their cardiac function was getting well as their thoracic index improved.
