Cardiac Catheterization

Improves Recovery Time

Interventional cardiology specifically uses catheter based diagnosis and treatment procedures. A large number of procedures can be completed on the heart using a catheter, typically with less pain, time in the hospital, and improved recovery than other methods of treating heart disease.

Stenting

A small mesh tube called a stent is usually placed in the newly widened part of the artery during an angioplasty. The stent holds up the artery and lowers the risk of the artery narrowing again. Stents are made of metal mesh and look like small springs.

Angioplasty

Percutaneous transluminal coronary angioplasty (PTCA) is performed to open blocked coronary arteries caused by coronary artery disease (CAD) and to restore arterial blood flow to the heart tissue without open-heart surgery. A special catheter (long hollow tube) is inserted into the coronary artery to be treated. This catheter has a tiny balloon at its tip. The balloon is inflated once the catheter has been placed into the narrowed area of the coronary artery. The inflation of the balloon compresses the fatty tissue in the artery and makes a larger opening inside the artery for improved blood flow.

Catheterization

Cardiac catheterization is a medical procedure used to diagnose and treat certain heart conditions. A long, thin, flexible tube called a catheter is put into a blood vessel in your arm, groin (upper thigh), or neck and threaded to your heart. Through the catheter, doctors can perform diagnostic tests and treatments on your heart.

WATCHMAN: A One-Time Implant that Helps Reduce AFib Stroke Risk

Mary Washington Hospital adds Watchman treatment for Atrial Fibrillation to its heart patient services.

How Does AFib Increase Stroke Risk?

The average person with atrial fibrillation (also called AFib or AF) is five times more likely to have a stroke than someone with a regular heartbeat.1 That’s because AFib can decrease the heart’s pumping capacity by as much as 30%.2 Because blood isn’t pumped out of the heart normally, it’s easier for blood cells to stick together and form clots in an area of the heart called the left atrial appendage (LAA).2, 3 When a blood clot escapes from the LAA and travels to another part of the body, it can cut off the blood supply to the brain, causing a stroke.1, 4

An Alternative to Blood Thinners

WATCHMAN is a permanent implant that offers an alternative to the lifelong use of blood thinners. It’s about the size of a quarter and made from very light and compact materials commonly used in many other medical implants.

How WATCHMAN Works

WATCHMAN effectively reduces the risk of stroke by permanently closing off the LAA to keep blood clots from escaping. WATCHMAN can eliminate the bleeding risks and regular blood tests and food-and-drink restrictions that come with warfarin. In a clinical trial, 9 out of 10 people were able to stop taking warfarin just 45 days after the WATCHMAN procedure.6

How is WATCHMAN Implanted?

WATCHMAN is implanted into your heart in a one-time procedure. To implant WATCHMAN, your doctor makes a small cut in your upper leg and inserts a narrow tube, as done in a standard stent procedure. Your doctor then guides WATCHMAN into your heart’s LAA. The procedure is done under general anesthesia and takes about an hour. Patients commonly stay in the hospital overnight and leave the next day.

After the Procedure

Following the WATCHMAN procedure, you’ll take warfarin for 45 days or until your LAA is permanently closed off. During this time, heart tissue will grow over the implant to form a barrier against blood clots. Your doctor will monitor this process by taking pictures of your heart to see when you can stop taking warfarin.

Your doctor will then prescribe a medicine called clopidogrel (also known as Plavix®) and aspirin for you to take for six months. After that, you’ll continue to take aspirin on an ongoing basis. A very small number of patients may need to keep taking blood thinners long term.

In a clinical trial:

  • 92% of patients were able to stop taking warfarin just 45 days after the procedure6
  • 99% of patients were able to stop taking warfarin within 1 year after the procedure6

Is WATCHMAN Right for You?

If you have a history of bleeding or a lifestyle, occupation or condition that puts you at risk for bleeding, WATCHMAN may be right for you. But like any medical procedure, WATCHMAN comes with risks, so it isn’t right for everyone.

Your cardiologist will weigh your risk of a stroke against your risk of a serious bleeding problem to determine the right treatment for you.
