TAVR and Aortic Stenosis: What You Need to Know

Updated July 2026

When a public figure in their seventies bounces back from heart surgery quickly enough to be dancing on stage within weeks, people are understandably amazed. Part of that speedy recovery comes down to a remarkable, minimally invasive procedure called TAVR. The other part comes down to something within reach of the rest of us: being as healthy as possible going into any procedure in the first place. Here's what's worth understanding about both.

What is TAVR (transcatheter aortic valve replacement)?

TAVR is a way to replace the heart's aortic valve without open-heart surgery. The aortic valve is the one-way door that controls blood flow out of the heart to the rest of the body. In a traditional valve replacement, a surgeon opens the chest, cuts through the breastbone, and places the patient on a heart-lung machine. TAVR does the same job through a catheter, usually threaded up from an artery in the groin, so there's no chest incision and no heart-lung bypass. Recovery is dramatically faster as a result, which is why someone can be up and moving again in a fraction of the time that open-heart surgery would require.

This short video illustrates what happens during the procedure:

What is aortic stenosis?

Aortic stenosis is a progressive narrowing of the aortic valve, which restricts the heart's ability to push blood out to the body. As the opening tightens, the restriction eventually starts to limit what a person can do physically, since the body can't get the blood flow it needs during exertion. It's the most common reason someone would need a procedure like TAVR, and it becomes more common with age. Sometimes a congenital defect in the valve makes the degeneration happen faster.

In some sense, it's amazing the valve holds up as long as it does. Think about it: that valve opens and closes with every heartbeat, 60 or more times a minute, 60 minutes an hour, 24 hours a day, for potentially a hundred years. If you opened and closed your front door 60 times a minute, it would fly off its hinges in three months.

Can you prevent aortic stenosis?

Not entirely, but you may be able to slow it down. Aortic stenosis is fundamentally a mechanical problem that can't be fixed with drugs. However, the same lifestyle factors that drive heart disease in general, high cholesterol, smoking, high blood pressure, and diabetes, appear to accelerate the mechanical degeneration of the valve. So controlling those risk factors may help keep your valves in better shape, in addition to keeping your arteries clean. It's one more example of how the fundamentals protect more of your cardiovascular system than most people realize.

Why does overall health matter so much before a procedure?

Because resilience is built in advance. The reason some people bounce back from surgery so quickly is that they walked in healthy: physically active, eating well, and pursuing activities they enjoy. Maintaining a healthy lifestyle makes you more resilient in general, so you can recover faster from just about any health setback. And it's never too late, even in your seventies, eating well, staying active, and staying engaged can keep you as energetic as someone decades younger, and in far better shape to weather whatever comes.

None of this means procedures and medications don't matter, they absolutely do, and modern cardiology can do remarkable things. But the healthier you are going in, the better you tend to come out. That part has always been, and remains, largely in your hands.
