What is an AV canal heart defect?
What is Atrioventricular Septal Defect? An atrioventricular septal defect (AVSD) is a heart defect in which there are holes between the chambers of the right and left sides of the heart, and the valves that control the flow of blood between these chambers may not be formed correctly.
Does AVSD mean Down syndrome?
ATRIOVENTRICULAR SEPTAL DEFECT (AVSD) AVSD is the most frequently diagnosed congenital heart condition in children with Down syndrome. Various studies place the incidence rate between 30 and 47 percent of CHDs in children with Down syndrome, according to the book Advances in Research on Down Syndrome.
How do you treat atrioventricular canal defect?
Treatment for atrioventricular canal defects Complete AV canal defects require surgery, usually within the first two or three months of life. The surgeon will close the large hole with one or two patches. The patches are stitched into the heart muscle, and as the child grows, the tissue grows over the patches.
What is AV canal repair?
Untreated, atrioventricular canal defect can cause heart failure and high blood pressure in the lungs. Doctors generally recommend surgery during the first year of life to close the hole in the heart and to reconstruct the valves.
Is AVSD the same as AV canal?
Atrioventricular septal defect (AVSD), or AV canal, is a heart defect that involves the valves between the heart’s upper and lower chambers and the walls between the chambers. Other terms used to describe this problem include endocardial cushion defect and AV canal defect.
How is AVSD repaired?
Open-heart surgery is the mainstay of treatment for children with AVSD. The repair involves placement of one or two patches to divide the common valve into right and left sides and close the holes. This is performed after beginning heart/lung bypass to support the circulation during the repair itself.
What is best technique for repair of complete atrioventricular canal?
Of these, the modified single-patch is currently the best technique available for repair of CAVC.
What is a common atrioventricular canal?
Complete common atrioventricular canal defect (CAVC) In this condition, there is a hole in the center of the heart, between the top chambers (atria) and the lower chambers (ventricles).
