Aortic stenosis is a condition that is growing as the U.S. population grows. Right now, it is estimated that 2.5 million Americans over 75 suffer from this heart valve disease, which accounts for 12.4 percent of the population.  Between now and 2050, the elderly population will more than double to around 80 million.

Aortic stenosis affects men more often than women. In fact, 80 percent of adults with aortic stenosis are male. What is aortic stenosis exactly? With this condition, the aortic valve’s flaps (cusps) have thickened or become stiff and could possibly fuse together, which narrows the valve. The valve’s opening becomes narrowed and blocks/reduces blood flow from the heart into the aorta and to the rest of the body.

A person with aortic stenosis will experience the following symptoms: shortness of breath, heart murmur, dizziness, fainting, chest pain, chest tightness, irregular heartbeat, and swelling of the ankles and feet.

The disease is often misdiagnosed and undertreated. A severe case of aortic stenosis can be fatal; some doctors refer to the disease as a “silent killer.”  It is a progressive disorder, and the onset of the symptoms and progression will vary from patient to patient. As a person gets older, the aortic valve disease will continue to progress, regardless of what the patient does or doesn’t do.

Since nothing can reduce the progression of this disease, patients are instructed to visit their cardiologist annually, and have an echocardiogram to evaluate is the disease is becoming more severe.  Aortic stenosis has three progression stages: mild, moderate, and severe.  As stated earlier, a person can experience an array of different symptoms with this disease. If a person is experiencing symptoms, it is often a sign of a progression of the degenerative process, and the person should have the doctor assess them immediately.

If a person gets to the point in which he or she needs an aortic valve replacement, they have more options for surgery than ever before. These days, there are less invasive approaches to aortic valve replacement such as transcatheter aortic valve replacement (TAVR).  TAVR is good for people who have been diagnosed with severe aortic valve disease and are at an intermediate or high risk for open heart surgery. Most people who have this procedure are in their 70s or 80s. In this surgery the doctor inserts a catheter in a leg or chest and guides it to the heart. A replacement valve is inserted through the catheter up to the heart.

Today, we are going to discuss a treatment method for aortic stenosis and aortic regurgitation – two serious conditions that affect the heart’s aortic valve – called Mini-AVR.

First, let’s talk about what those conditions are.

Aortic stenosis occurs when the cusps of the aortic valve become abnormally rigid and do not fully open. This narrowing of the valve creates resistance against the pumping of blood from the left ventricle to the rest of the body, and if left untreated, it can lead to heart failure.

Typically, this condition is the result of degeneration due to natural aging and health issues and calcium buildup on the valve cusps over time causes them to stiffen.

Aortic regurgitation occurs when the aortic valve allows blood to leak back into the left ventricle. It’s often caused by valve damage due to a recent infection or rheumatic heart disease, or it’s a congenital heart defect you were born with.

The symptoms of both conditions include shortness of breath, chest pain or heaviness, fainting or lightheadedness, decreased physical endurance during exercise, and swelling of the limbs.

The severity of aortic stenosis and aortic regurgitation will determine treatment. A Minimally Invasive Aortic Valve Replacement, or Mini-AVR, involves the surgical replacement of the aortic valve with a prosthetic valve. Its benefits include less trauma and pain, better cosmetic results, a shorter recovery time, and a potentially lower financial cost.

During Mini-AVR surgery, a small incision is made in the upper chest area, and a cardiopulmonary bypass machine is used to take over functions of the heart and lungs, so that blood continues to flow around the heart and the body’s oxygen levels remain stable. A surgeon will open the aorta (and, if necessary, remove any diseased valve cusps), measure the valve ring, and insert the prosthetic valve.

The surgery typically takes about 2 to 3 hours. Several recent studies have shown that a Mini-AVR procedure is potentially safer than a conventional AVR procedure with a full sternotomy, which calls for much larger incision.

It’s important to talk to your doctor about the best treatment options for aortic valve conditions. In some cases, medication may be effective treatment for aortic regurgitation. However, receiving timely surgery is often advised because a significant delay could lead to congestive heart failure.
