Insights
This study examined congenital heart disease (CHD) in Oman, finding simple forms are common but complex cases have shorter survival. A national registry is recommended for better CHD management and outcomes.
Area of Science:
- Cardiology
- Public Health
- Pediatric Medicine
Background:
- Congenital heart disease (CHD) represents a significant global health concern.
- Understanding the epidemiology of CHD in specific populations is crucial for targeted interventions.
Purpose of the Study:
- To investigate the spectrum, demographics, and mortality rates of congenital heart disease (CHD) in Omani adolescents and adults.
- To analyze survival outcomes based on CHD type and patient demographics.
Main Methods:
- Retrospective analysis of electronic health records from the Royal Hospital, Muscat.
- Inclusion of patients aged 13 years and above diagnosed with CHD.
- Kaplan-Meier survival analysis to assess in-hospital mortality.
Main Results:
- 600 CHD patients identified; 24% were 18 years or younger, with a median age of 24.
- Simple CHDs, particularly atrial and ventricular septal defects (62.8%), were most prevalent.
- Patients with Tetralogy of Fallot and Fontan experienced shorter survival times compared to literature benchmarks.
Conclusions:
- Oman's CHD population primarily consists of younger individuals with simpler heart defects.
- Complex congenital heart lesions are associated with significantly reduced survival rates.
- Establishing a national CHD data registry is essential for improving disease management and reducing mortality.
Objectives:
The aim of our study was to examine the spectrum, demographics, and mortality rate among adolescents and adults with congenital heart diseases (CHD) in Oman.
Methods:
Data was collected retrospectively from the Royal Hospital, Muscat, electronic health records for all patients with a diagnosis of CHD aged 13 years and above. Data was analyzed according to the type of CHD and in-hospital mortality was assessed using Kaplan-Meier survival analysis.
Results:
A total of 600 patients with CHD were identified, among them 145 (24%) were aged 18 years or below. The median age was 24 years. The majority of patients had a simple form of CHD. Atrial and ventricular septal defects together constituted 62.8% of congenital heart diseases. Most patients were clustered in Muscat (32%) and the Batinah regions (31.1%) of Oman. Patients with tetralogy of Fallot and Fontan had shorter survival time than recorded in the published literature.
Conclusion:
Mostly simple forms of CHD in younger patients was observed. The survival rate was significantly shortened in more complex lesions compared to simple lesions. A national data registry for CHD is needed to address the morbidities and mortality associated with the disease.
