Aortic Stenosis: Symptoms, Diagnosis & New TAVR Treatment Options

Aortic stenosis, a progressive narrowing of the aortic valve in the heart, is a serious condition that primarily affects older adults, though symptoms can emerge as early as a person’s 50s or 60s. The condition restricts blood flow from the heart, impacting oxygen delivery throughout the body and potentially leading to severe health consequences, including sudden cardiac death.

Understanding the Aortic Valve and Stenosis

As Dr. Ahmed Elkaryoni, a cardiologist at Memorial Health, explains, the heart has four valves – two on the right side and two on the left. The aortic valve, located on the left side, is crucial for ensuring blood is pumped effectively to the brain and all the body’s organs. “That’s where blood would go everywhere,” Dr. Elkaryoni said. “It goes to the brain, supplies all the organs, the lungs, liver, kidneys, and everything.”

Aortic stenosis develops over time, often due to calcium deposits on the aortic valve. This causes the valve to stiffen and narrow, hindering its ability to open fully. The progression typically unfolds in stages – mild, moderate, and severe – and can take years. Unfortunately, there are currently no medications available to halt this progression.

Recognizing the Symptoms

In its early stages, aortic stenosis is often asymptomatic, meaning individuals may not experience any noticeable symptoms. However, as the condition worsens, symptoms begin to appear. These can include lightheadedness, dizziness, shortness of breath, and chest pain. In severe cases, individuals may even lose consciousness due to insufficient blood flow to the brain.

Monitoring Progression and the Role of Echocardiograms

The rate of progression varies significantly from person to person. Dr. Elkaryoni notes that, on average, the valve tends to become slightly tighter every six months, increasing the velocity of blood flow across the narrowed opening. This progression is monitored using echocardiograms, a non-invasive imaging technique that allows doctors to assess the severity of the stenosis.

“Mild to moderate may take years; moderate may take a few years until you reach severe,” Dr. Elkaryoni explained. “Once you hit the range of moderate to severe, every six months Make sure to get an echocardiogram to evaluate for the severity. Once you hit the severe range, you have to be treated.”

Treatment Options: From SAVR to TAVR

For many years, surgical aortic valve replacement (SAVR) was the primary treatment option for severe aortic stenosis. SAVR involves opening the chest to access and replace the damaged valve. However, this invasive procedure may not be suitable for all patients, particularly the elderly or those with other health conditions.

Fortunately, a less invasive alternative, known as transcatheter aortic valve replacement (TAVR), is becoming increasingly available. TAVR involves inserting a new valve via a catheter, typically through an artery in the leg, eliminating the need for open-heart surgery. Memorial Health is preparing to offer TAVR to its patients soon.

Understanding TAVR

TAVR represents a significant advancement in the treatment of aortic stenosis, offering a potentially less risky and more accessible option for many patients. The Cleveland Clinic notes that valve replacement is the best treatment for aortic stenosis and generally provides a good prognosis. While the provided information doesn’t detail the specifics of TAVR, it highlights its growing importance as a treatment modality.

The Importance of Early Detection and Regular Check-ups

Given the progressive nature of aortic stenosis and the potential for serious complications, early detection and regular monitoring are crucial. Individuals, especially those over 60 or with a family history of heart valve disease, should discuss their risk factors with their healthcare provider. Even in the early stages, regular check-ups and echocardiograms can help track the progression of the disease and ensure timely intervention when necessary.

Aortic stenosis is a condition that demands attention, but with advancements in diagnostic tools and treatment options like TAVR, individuals can proactively manage their heart health and improve their quality of life.
