What are atrioventricular canal defects? An atrioventricular (AV) canal defect is a problem in the part of the heart that connects the upper chambers (atria) to the lower chambers (ventricles). There are two types of atrioventricular canal defects: complete and partial.

Atrioventricular (AV) canal defect is a large hole in the center of the heart. It's located where the wall (septum) between the upper chambers (atria) joins the wall between the lower chambers (ventricles).

2023年7月19日 · Atrioventricular canal defects (AVCDs) comprise a spectrum of defects such as exclusive ventricular or atrial defects, septal defects, atrioventricular anomalies, and endocardial cushion defects. AVCDs are more commonly associated with chromosomal abnormalities, especially trisomy 21.

What is atrioventricular canal defect? An atrioventricular canal defect, or AV canal, is a combination of several closely associated heart problems that result in a large defect in the center of the heart.

2022年9月13日 · Atrioventricular canal defect might be diagnosed in a baby before birth during a pregnancy ultrasound or special heart imaging. After birth, symptoms of complete atrioventricular canal defect are usually noticeable within the first weeks.
