Q21.2
Atrioventricular septal defect
Clinical Classification Guidelines
Inclusion Terms
- Atrioventricular canal defect
- Endocardial cushion defect
- Ostium primum atrial septal defect (type I)
Medical Intelligence & Overview
Atrioventricular septal defect (AVSD), also known as atrioventricular canal defect or endocardial cushion defect, is a congenital heart condition characterized by abnormal development of the heart's septa and valves. This defect involves openings in the walls that separate the heart's chambers and can affect how blood flows through the heart. It is most commonly diagnosed in infants and young children, but some cases may remain undetected until later childhood or adulthood.
Causes & Symptoms
Clinical Causes: Genetic syndromes, such as Down syndrome Family history of congenital heart defects Environmental factors during pregnancy, including maternal alcohol consumption, diabetes, or medication use Random developmental errors during fetal heart formation
Key Symptoms: Difficulty breathing or rapid breathing Poor feeding and failure to thrive Frequent respiratory infections Fatigue easily during activity Heart murmurs detectable with auscultation Swelling in the abdomen or legs due to fluid buildup Cyanosis (a bluish tint to the skin, especially around the lips and fingertips)
Diagnostic & Treatment
Diagnosis Path: Diagnosis of atrioventricular septal defect involves a combination of clinical examinations and diagnostic tests, including: - Echocardiogram: The primary tool that uses ultrasound waves to create images of the heart, revealing the size and location of septal openings and valve abnormalities. - Electrocardiogram (ECG): To assess electrical activity and detect abnormal heart rhythms. - Chest X-ray: To visualize heart size and pulmonary blood flow. - Cardiac MRI or cardiac catheterization: Sometimes used for detailed imaging or to evaluate blood flow and pressure in the heart. Early detection is crucial to manage symptoms effectively and plan appropriate treatment strategies.
Treatment Protocols: Treatment options depend on the severity of the defect and the presence of symptoms. They may include: - Medical Management: Use of medications such as diuretics, ACE inhibitors, or other drugs to manage symptoms like heart failure or pulmonary hypertension. - Surgical Repair: Typically performed in infancy or early childhood, involving closure of the septal openings and correction of valve abnormalities. Common procedures include atrioventricular septal defect repair, which aims to restore normal heart function. - Monitoring and Follow-Up: Regular cardiac evaluations post-treatment to ensure the heart continues to function effectively and to monitor for potential complications. Early and appropriate intervention can significantly improve outcomes and quality of life for individuals with AVSD.
