Left Atrial Appendage Closure Procedure (Watchman™)

Left Atrial Appendage Closure Procedure

In people with atrial fibrillation (A-fib), not caused by a heart valve issue, stroke is a serious risk. More than 90% of stroke-causing clots that come from the heart are formed in the left atrial appendage, which is an out-pouching of tissue in the left atrium of the heart. If you are a patient with A-fib who has an increased risk of stroke, your doctor will recommend that you take a blood-thinning medicine. If you are unable to take a blood thinner because of risk of bleeding or falls, your doctor may recommend a procedure to implant a device to block off your left atrial appendage, which would prevent stroke-causing clots from forming there.

The Watchman is a permanent, implant-based alternative to the long-term use of blood thinners, such as warfarin. The procedure has been shown to reduce the risk of stroke without the long-term increased risk of bleeding associated with chronic use of blood thinners.

Watchman

The Watchman is about the size of a quarter and made from very light and compact materials commonly used in many other medical implants. It is designed to permanently close off the left atrial appendage and keep blood clots from forming in this area of the heart, significantly decreasing your risk of stroke.

Norton Heart & Vascular Institute has been performing Watchman implants since 2016, which is longer than any other hospital system in Louisville or Southern Indiana.

Benefits of a Left Atrial Appendage Closure

There are many benefits of having a left atrial appendage closure procedure with the Norton Heart & Vascular Institute team. They include:

  • Reduced risk of stroke from blot clots formed in the left atrial appendage
  • Eventual discontinuation of blood thinner, in most cases 45 days after the procedure
  • Minimally invasive, with no stitches needed
  • Short (overnight) hospital stay

Who Is a Candidate for the Watchman Implant Procedure?

You may be a candidate if you:

  • Have A-fib that is not related to heart valve disease (non-valvular atrial fibrillation) and are at an increased risk of stroke
  • Have a history of major bleeding while taking blood thinners
  • Have a lifestyle, occupation or condition that puts you at risk for bleeding

How Is the Procedure Performed?

A specially trained cardiologist inserts flexible wires (catheters) into a blood vessel in the groin and guides the Watchman device into the heart. Once the device is in the correct place, the physician sets the implant to permanently seal off the left atrial appendage. Over time, heart tissue grows over the implant. The procedure takes place in an electrophysiology lab under general anesthesia and lasts about an hour.

Norton Heart & Vascular Institute has a state-of-the-art electrophysiology lab at Norton Hospital where this procedure is performed.
