Insights

Congenital heart disease (CHD) affected 7.1 per 1000 live births in Oman. The study found common CHDs like ventricular septal defects and a higher frequency of atrioventricular septal defects compared to global data.

Area of Science:

  • Cardiology
  • Pediatrics
  • Public Health

Background:

  • Congenital heart disease (CHD) represents a significant global health concern.
  • Understanding the epidemiology of CHD is crucial for effective public health strategies and resource allocation.

Purpose of the Study:

  • To determine the incidence and spectrum of congenital heart disease (CHD) in the Sultanate of Oman.
  • To compare Omani CHD patterns with international data.

Main Methods:

  • A hospital-based study analyzing live births between 1994 and 1996.
  • Data collected on 139,707 live births to identify and categorize cases of CHD.

Main Results:

  • An overall incidence of CHD was found to be 7.1 per 1000 live births.
  • The most common CHDs were ventricular septal defect (24.9%), atrial septal defect (14.4%), and patent ductus arteriosus (10.3%).
  • A higher frequency of atrioventricular septal defects (5.9%) was observed compared to other countries. Cyanotic CHD accounted for 21.7% of cases.

Conclusions:

  • The incidence and pattern of CHD in Oman are largely similar to developed nations, with a notable exception of increased atrioventricular septal defects.
  • Early diagnosis was achieved, with 38% diagnosed under one month and 40% between 1-12 months.
  • Consanguinity did not appear to influence the overall incidence of CHD in the Omani population.

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health condition at a...

Mitral Stenosis I: Introduction

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

Mitral Stenosis II: Clinical features and Diagnostic Tests

Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
