Insights
This study analyzed ventricular septal defect (VSD) in Moroccan children, finding surgical closure is best for long-term outcomes. Palliative banding serves as a temporary measure for VSD patients.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease Epidemiology
Context:
- Ventricular septal defect (VSD) is a common congenital heart defect.
- Understanding VSD epidemiology in specific regions like Morocco is crucial for healthcare planning.
Purpose:
- To analyze the epidemiologic, anatomic, clinical, and prognostic aspects of VSD in Moroccan children.
- To evaluate treatment outcomes for VSD in a pediatric population.
Summary:
- A retrospective study of 44 pediatric VSD patients in Morocco revealed common symptoms like failure to gain weight and dyspnea.
- Membranous defects were most common (88%), with 31.7% undergoing surgery.
- Surgical VSD closure led to positive outcomes, while palliative banding was temporary.
Impact:
- Highlights the importance of timely surgical VSD correction to prevent irreversible pulmonary hypertension.
- Provides regional data on VSD, aiding in targeted interventions and resource allocation.
- Emphasizes surgical VSD repair as the definitive treatment for improved pediatric cardiac health.
Objectives:
The aim of this study is to analyze epidemiologic, anatomic, clinical and prognostic aspects of ventricular septal defect (VSD) in the pediatric population in Morocco.
Methods:
This retrospective descriptive study included 44 consecutive patients admitted to the cardiology B department of Rabat University Hospital Center from January 2000 through March 2003. The inclusion criteria were: VSD, isolated or associated with other left-right shunt defects, diagnosed by transthoracic echocardiography, and hospitalized in the service.
Results:
VSD accounted for 10.6% of the congenital cardiac diseases hospitalized in our department. Patients' mean age was 2.25 +/- 2.6 years; the consanguinity rate was 29%. The primary clinical symptoms were dominated by failure to gain weight (84%), exertional dyspnea (82%), and repeated bronchitis (72%). Early complications were infundibular stenosis (4 cases), aortic regurgitation (3 cases), and infectious endocarditis (1 case). Nine children had other abnormalities, including 6 with trisomy 21. Echocardiography showed that membranous defects were by far the most common type (88%). All patients received symptomatic medical treatment. Only 31.7% (n=14) had surgery: 11.3% (n=5) to close the hole (corrective) and 20.4% (n=9) for pulmonary artery (palliative) banding. After two years of follow-up, those with surgical correction were all doing well.
Conclusion:
Surgically closing the VSD is the best way to avoid irreversible pulmonary arterial hypertension; banding should be only a temporary measure while awaiting corrective surgery.
