Understanding Atrioventricular Canal Defect
Atrioventricular canal defect, also known as AV canal defect, is a congenital heart defect that affects the structure of the heart. It is characterized by abnormalities in the walls and valves that separate the heart’s chambers, causing a mixing of oxygenated and deoxygenated blood.
The AV canal defect can vary in severity, ranging from partial to complete. In the most severe cases, it can lead to significant heart abnormalities and impaired circulation. The defect is commonly associated with other congenital heart defects, such as ventricular septal defect and atrial septal defect.
There are three main types of atrioventricular canal defects:
- Complete AV Canal Defect: This type involves a large hole in the center of the heart, affecting both the atrial and ventricular septa as well as the valves that control blood flow.
- Partial AV Canal Defect: In this type, only one part of the atrioventricular canal is affected, either the atrial or ventricular septum, or one of the valves.
- Intermediate AV Canal Defect: This type lies between the complete and partial defects, with a smaller hole and less severe anomalies.
These different types of AV canal defect can have varying degrees of impact on heart function and circulation. The severity and symptoms experienced by individuals with AV canal defect will depend on the specific type and extent of the defect. Atrioventricular Canal Defect: Causes & Treatment
Understanding the specifics of each type of atrioventricular canal defect is crucial for accurate diagnosis and appropriate treatment decisions. It enables healthcare professionals to develop tailored treatment plans that address the unique needs and challenges of each individual patient.
