What is Aortic Stenosis?
Reading time: 2 min
Aortic stenosis is a disease that occurs due to narrowing of the aortic valve, one of the four valves that control blood flow in the heart, which makes it difficult for the blood to pass through. It manifests as shortness of breath, chest pain, dizziness and loss of consciousness. Aortic stenosis affects 4% of the population, and it is more frequent in people aged 70 and over.

Aortic stenosis is asymptomatic for many years because the valve is affected, but enough blood still flows out of the heart to be able to live a normal life.

"What I noticed with this operation after they repaired this fault is that I don't get tired, I’m not out of breath on slopes. So, it has definitely improved my life, a lot."

The heart is a muscle that drives blood through the body. Blood transports the nutrients and oxygen necessary for all organs and tissues in our body to function properly. It is made up of four chambers: two atria (which receive the blood) and two ventricles (which pump blood out). There are also four heart valves that act as gateways between these chambers and between the heart and the rest of the body, ensuring that the blood moves in the right direction.
The aortic valve is the outflow valve of the left ventricle, which separates the heart from the rest of the body. As the heart contracts with each beat, the blood passes through the aortic valve to the rest of the body. After this, the valve closes, preventing the blood from flowing back to the heart.
The normal aortic valve has three ‘leaflets’ or gateways that open and close to ensure the blood flows properly.
When the aortic valve is tightened, what we call medically stenotic, the veils become stiff and thick and tighten the orifice through which the blood circulates.
