Valvar aortic stenosis, commonly called aortic stenosis, is a disorder which occurs when the aortic valve of the heart becomes narrow (know Main Indicators of a Heart Disease in a Child). The narrowing of the valve prevents its full opening, and hence, blood flow from the heart to the aorta is restricted. When the aortic valve gets obstructed, the heart has to exert much more effort to pump the blood. The heart muscles get weakened as a result. This condition is more common in children.

Diagnosis of Valvar Aortic Stenosis:
Before diagnosis, we should know about the symptoms of valvar aortic stenosis in children. They include:

• Feeling breathless
• Angina or chest pain with a feeling of pressure or tightness
• Syncope of fainting
• Palpitations and enhanced heartbeats
• A steady decline in regular activities and energy levels
• Fatigue due to little exertion
• Not gaining weight
• Poor eating patterns
• Problems in breathing

The wall of the left ventricle also thickens muscularly, and the thick wall occupies more space in the lower chamber of the heart and hence, the room for adequate blood supply is reduced. This may lead to heart failure.

Echocardiogram: The initial test that is recommended for patients with symptoms of valvar aortic stenosis is Doppler Echocardiography. This test enables the doctor to estimate the aortic valve region, peak or mean transvalvular gradients and the maximum aortic velocity. These primary measures are required to assess the severity of the disease. Echocardiography provides important information on the valve function, left ventricular filling pressure and disruptions in other valves.

Other major tests which help in the diagnosis of valvar aortic stenosis include:

• MRI or magnetic resonance imaging, which provides images of internal body structures with great detail.
• CT scan or computed tomography where three-dimensional images are extracted.
• Chest X ray
• Cardiac catheterization where a dye is used to highlight blockages, if any, in the heart.

Treatment: Usually, there are no medicines for fixing valvar aortic stenosis as the disease is not reversible. Medicines can be used to treat the problems, which are caused by the condition.

Replacement of the damaged valve by surgery is the best treatment for valvar aortic stenosis. The surgery performed is called valvuloplasty. This is a cardioscopic surgery where a tube with a small balloon is inserted into a vein. The tube is guided into the heart, and the balloon is inflated. The balloon and tube are removed after the valve is opened. The damaged valve is replaced by mechanical valve or the valve of a cow or pig by an open-heart surgery.

Valvar aortic stenosis is a severe heart condition in children, and the only permanent remedy for this disease is a valve replacement surgery.

Newborns primarily need your love, care, and attention. If you aren't sure whether you're on the right track with your little one, read on to find out the 3 most important things that your newborn needs:

1. Skin-to-skin contact: One of the best ways to speed up the bonding process with your newborn is by having as much as possible skin-to-skin contact with your child. This is important as the newborn connects through smell and touch during this time. The senses of your baby are naturally tuned to react to the feel of your bare skin and your distinctive smell.

Many studies also suggest that close physical contact can help in reducing stress in your newborn so as to allow its biological drive to come through and easily latch onto your breast to feed itself. In other words, it ensures a higher chance of getting the newborn started on breast milk in case your child is not taking to your breasts easily.

2. To be breastfed: The best food for your baby is milk that is produced by you. Breast milk offers a host of benefits that go beyond basic nourishment. According to research conducted by the national institute of environmental health sciences, a child faces 20% lower chances of dying between the ages of 28 days and 1 year if he or she is breastfed.
