Who is at risk for an atrioventricular canal defect?

Who is at risk for an atrioventricular canal defect?

Experts haven’t identified exact risk factors for this heart condition. Genetics may be a factor. A baby can inherit an abnormal gene or genes from a parent, which may make them more likely to develop a heart condition in the uterus (womb).

Other risk factors during pregnancy that may increase the chances of giving birth to a baby with a congenital heart defect include:

• Certain medications.
• Recreational drug or alcohol use.
• Exposure to environmental toxins or chemicals.
• Nutrient or vitamin deficiencies.
• Having obesity.
• Smoking or using tobacco products.
• Unmanaged chronic health conditions, such as diabetes or high blood pressure (hypertension).
• Viruses or fevers, such as influenza (flu).
