Normally, the impulse travels first through the atria and then through a connecting pathway between the upper and lower chambers of your heart called the atrioventricular (AV) node.
She suffers from a congenital condition known as atrioventricular septal defect (AVSD) - a complex hole between the right and left sides of her heart, compounded by a drastically undersized left ventricle - the chamber that pumps fresh, oxygenated blood from her lungs to the rest of her body.
Jamie Goodier was diagnosed with life-threatening abnormality called atrioventricular septal defect.
As the signal goes from the atria to the ventricles, it passes through specialized conducting tissue called the atrioventricular (A'tre-o-ven-TRIK'u-ler) (AV) node.
There are two types of atrioventricular canal defect: complete and partial.
Sometimes complete atrioventricular canal is diagnosed on a fetal ultrasound and/or echocardiogram.
Partial atrioventricular canal causes fewer symptoms and sometimes isn't diagnosed until the child reaches his or her 20s or 30s, and begins to experience irregular heartbeat (arrhythmia), leaky valves or other effects.
Complete atrioventricular canal often occurs in children with Down syndrome.
Partial atrioventricular canal is also called atrioventricular septal defect, or AVSD.
A child who has had surgical repair of atrioventricular canal will require life-long care by a cardiologist.
