Aortic stenosis means your aortic valve does not open widely enough to allow adequate blood flow from your heart to your aorta.
At the UPMC Heart and Vascular Institute, we offer the full range of treatments for aortic stenosis including surgical and minimally invasive valve replacement. In fact, we were one of the first medical centers to perform transcatheter aortic valve replacement (TAVR) — a minimally invasive treatment for severe aortic stenosis.

An aneurysm occurs when a blood vessel stretches or bulges in one place. An aortic root aneurysm occurs in the beginning, or root, of the aorta.
The aorta is the body's largest blood vessel. It transports blood to the body from the heart.
Doctors also call an aortic root aneurysm a dilated aortic root.
Certain health problems increase the risk for aortic root aneurysms, including genetic or connective tissue disorders such as:
Autoimmune or inflammatory diseases that affect the arteries also raise risk.
These include:
Other health and lifestyle factors that increase aortic root aneurysm risk are:
Aortic root aneurysms can also result from birth defects of the heart or blunt trauma (an extreme blow) to the chest.
The aortic root has a valve that allows blood to pass from the heart to the aorta.
When the heart pumps blood out, the valve opens. The valve then closes to prevent blood from flowing back in from the aorta.
When an aneurysm stretches the aorta, the valve can't fully close. Because the valve stays open, the blood pumped into the aorta can flow back into the heart.
This causes problems such as:
Though some people are at higher risk for this disease, it doesn't mean they'll form an aortic root aneurysm.
If you're at higher risk for an aortic root aneurysm, ways to help prevent it include:
If you received an aortic root aneurysm diagnosis, you should:

Aortic root aneurysms often have no symptoms.
Some possible aneurysm symptoms are:
If the aneurysm dissects or ruptures, symptoms include:
An aneurysm dissection or rupture is a medical emergency. Seek treatment right away.
Doctors tend to find this type of aneurysm by chance when taking an x-ray or CT scan for another health reason.
Your heart doctor might screen you for an aortic root aneurysm if you have certain diseases that increase your risk.
Tests to diagnose aortic root aneurysms include an x-ray or ultrasound of the heart.
If the results show a possible aneurysm, your doctor might order more tests, such as an MRI or CT angiogram. These tests let your doctor see the size of the aneurysm and plan treatment.

Need for treatment depends on the size of your aneurysm and any other health issues you may have.
The aortic root dilation, or bulge, may grow larger. It will not shrink on its own.
If your aneurysm is 50 percent larger than the rest of the artery, you may need surgery. Doctors mainly suggest surgery when an aortic root dilation reaches 5 centimeters.
If the aneurysm is small and not causing any problems, your doctor may suggest waiting to see if the aneurysm is growing.
Doctors can treat this type of aneurysm either by:
If you or a family member received an aortic root aneurysm diagnosis, it's vital to know the risks of waiting versus treatment.
A connective tissue disorder or other health condition may increase your risk of rupture, even for a small aneurysm.
The risks of aortic root aneurysm surgery are:
A ruptured aneurysm is a medical emergency that may be fatal if not treated right away.
