Atrioventricular

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. ❋ Unknown (2010)

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. ❋ Unknown (2009)

Jamie Goodier was diagnosed with life-threatening abnormality called atrioventricular septal defect. ❋ Unknown (2009)

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. ❋ Unknown (2008)

Sometimes complete atrioventricular canal is diagnosed on a fetal ultrasound and/or echocardiogram. ❋ Unknown (2009)

In complete atrioventricular canal, the following symptoms may be present within several days or weeks of birth: blue or purple tint to lips, skin and nails (cyanosis) difficulty breathing poor weight gain and growth heart murmur - the heart sounds abnormal when a doctor listens with a stethoscope ❋ Unknown (2009)

Also called atrioventricular septal defect or endocardial cushion defect. ❋ Unknown (2010)

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. ❋ Unknown (2009)

Complete atrioventricular canal often occurs in children with Down syndrome. ❋ Unknown (2009)

In a child with complete atrioventricular canal, there is one large valve, and it may not close correctly. ❋ Unknown (2009)

Complete atrioventricular canal requires surgery, usually within the first two or three months of life. ❋ Unknown (2009)

An atrioventricular canal defect is a problem in the part of the heart that connects the upper chambers (atria) to the lower chambers (ventricles). ❋ Unknown (2009)

There are two types of atrioventricular canal defect: complete and partial. ❋ Unknown (2009)

Phenytoin has been found to improve atrioventricular conduction and negligibly affects intraventricular conduction. ❋ Unknown (2010)

Partial atrioventricular canal is also called atrioventricular septal defect, or AVSD. ❋ Unknown (2009)

Partial atrioventricular canal is the less severe form of this heart defect. ❋ Unknown (2009)

Partial atrioventricular canal also requires surgery, whether it is diagnosed in childhood or adulthood. ❋ Unknown (2009)

A child who has had surgical repair of atrioventricular canal will require life-long care by a cardiologist. ❋ Unknown (2009)

Complete atrioventricular canal (CAVC) is a severe defect in which there is a large hole in the tissue (the septum) ❋ Unknown (2009)

Dilated cardiomyopathy and atrioventricular conduction blocks induced by heart-specific inactivation of mitochondrial DNA gene expression. ❋ Unknown (2007)
