What is Aortic Stenosis
Overview of the Disease
In elderly patients, aortic stenosis is sometimes caused by the buildup of calcium (mineral deposits) on the aortic valve’s leaflets. Over time, the leaflets become stiff, reducing their ability to fully open and close. When the leaflets don’t fully open, a person’s heart must work harder to push blood through the aortic valve to the rest of the body. Eventually, the heart gets weaker, increasing the risk of heart failure (when the heart cannot supply enough blood to the body).
Severe Aortic Stenosis
The symptoms listed below are typically associated with severe aortic stenosis but are commonly misunderstood by patients as “normal” signs of aging.
• Difficulty sleeping or the need to sleep sitting up
Major Risk Factors
Factors associated with aortic valve disease include the following:
Severe aortic stenosis is life-threatening, and treatment for this condition is critical. Patients who have developed symptoms from severe aortic stenosis have about a 50 percent chance of living at two years without aortic valve replacement.
Diagnosis
Aortic Valve Replacement Options
In preparation for the patient’s transfemoral procedure (or through the upper leg), the patient may be placed under anesthesia. The doctor will make an incision in the leg and insert a short, hollow tube called a sheath. This will allow the doctor to put various devices through the sheath to access the patient’s heart. The new heart valve is placed on the delivery system and compressed onto a balloon to make it small enough to fit through the sheath. Once the delivery system reaches the patient’s diseased valve, the balloon will be inflated with fluid, expanding the new valve into place. The new valve pushes the leaflets of the patient’s diseased valve aside, and the frame of the new valve uses the diseased valve’s leaflets to secure itself into place. The balloon is then deflated and removed. The patient’s doctor will ensure the new valve is working properly before closing up the incision.
Our skilled providers, Dr. Nandu Gourineni, Dr. Ramesh Chillal-Kashinath, Dr. David Hart, and Dr. Gregory Dedinsky, and the Heart & Vascular Team at Columbus Regional Health, are pleased to offer this minimally invasive option to patients so they can receive the best cardiac care close to home.
