AVC(Additional Voluntary Contribution): It is defined as an additional contribution pension arrangement provided by an insurance company to increase retirement benefits.
AVC(Audio Visual Conferencing): It is a telecommunication technology which provides a connection between two persons or parties from two different locations by both audio and video transmission at the same time.
AVC(Average Variable Cost): It is defined as the TVC(Total Variable Cost) divided by the number of units produced.
Another full form of AVC is the “Atrioventricular Canal”. It is a defect in the part of the heart which connects the atria, known as the upper chambers, to the ventricles, known as the lower chambers. It is commonly heard as a hole in the heart wall separating the chambers. This is a congenital disability which means it is present by birth. Along with this, valves of the heart, which separate oxygenated and deoxygenated blood, also have problems, such as allowing excess blood flow to the lungs. This defect is of two types: partial and complete atrioventricular defect.
It is less severe than a complete AVC defect. The hole present does not extend between the heart’s lower chambers. The valves are also minorly defective because the hole is present in the atrial that's why it is also known as an atrial septal defect(ASD).
It is a severe condition in which a large hole is present in the heart’s centre where the atrial and ventricles meet. In this condition, valves do not close properly, resulting in abnormal passage between the heart chambers and oxygenated blood mixed with deoxygenated blood. It creates a workload on the heart, and the muscles become enlarged and damaged if not treated properly.
Blue or purple colour to lips, skin and nails
Difficulty in breathing
Poor growth
Poor weight gain
Murmur/abnormal sound of heart
In both the partial and the complete AVC, defects require surgery in which the doctor stitches the hole present in the heart.
As this condition is present by birth, AV canal defect is usually diagnosed under the Fetal Heart Program. Some other tests required are Echocardiogram(ECG), Chest X-ray. Pulse oximetry, Cardiac MRI(Magnetic Resonance Imaging), etc.
This defect occurs before the birth of a child when the heart is developing in the mother’s womb.
Genetics, Diabetes, Alcohol consumption, Smoking during pregnancy, etc., increase the risk of AVC defect.
It can create several complications, such as Enlargement of the heart, High BP(Blood pressure), Respiratory tract infections, Heart failure, Breathing problems, Irregular heartbeats, etc.
