What is Complete Atrioventricular Canal (CAVC)?

Complete Atrioventricular Canal (CAVC) is a congenital heart defect that affects the structure of the heart. It involves a large hole in the center of the heart where the walls between the chambers should meet. This condition can lead to serious health issues if not treated properly.

CAVC is a congenital defect: This means it is present at birth. Babies are born with this heart condition, which can be detected through prenatal ultrasounds or after birth through symptoms.
Affects the heart's structure: The defect involves a large hole in the center of the heart, affecting the walls between the heart's chambers and the valves that control blood flow.
Common in Down syndrome: Approximately 45% of children with Down syndrome have some form of congenital heart defect, with CAVC being one of the most common.

Symptoms of Complete Atrioventricular Canal

Recognizing the symptoms of CAVC early can be crucial for timely treatment. Symptoms can vary depending on the severity of the defect.

Rapid breathing: Infants with CAVC often exhibit rapid or labored breathing due to the heart's inefficiency in pumping blood.
Poor weight gain: Babies may struggle to gain weight and grow at a normal rate because their bodies are working harder to pump blood.
Fatigue during feeding: Infants may tire quickly while feeding, leading to inadequate nutrition and slower growth.

Diagnosis of CAVC

Diagnosing CAVC involves several medical tests and procedures to confirm the presence and extent of the defect.

Echocardiogram: This ultrasound test uses sound waves to create images of the heart, helping doctors see the structure and function of the heart.
Chest X-ray: A chest X-ray can show an enlarged heart or fluid in the lungs, which are indicators of CAVC.
Electrocardiogram (ECG): This test records the electrical activity of the heart and can help identify abnormalities associated with CAVC.

Treatment Options for CAVC

Treatment for CAVC typically involves surgery to correct the defect and improve heart function.

Open-heart surgery: The most common treatment is open-heart surgery to close the hole in the heart and repair the valves.
Medications: Before surgery, medications may be prescribed to manage symptoms such as heart failure or high blood pressure.
Regular follow-ups: After surgery, regular follow-ups with a cardiologist are essential to monitor heart function and overall health.
