Medical and dental procedures

Peace of mind for your procedures

As a WATCHMAN™ Implant patient, you may need to take precautions when undergoing certain medical and dental procedures. You can find some general guidelines below, but be sure to let the doctor or dentist performing the procedure know you have a WATCHMAN Implant.

Procedures that may affect your device

If surgery or dental work requires you to stop taking your medications prematurely, you and your doctors should carefully consider the risks and benefits of this additional surgery or dental work versus the possible risks from stopping these medications early. Talk to your heart specialist and the doctor performing the procedure about the timing of any medical procedures you may need.

Magnetic Resonance Imaging (MRI)

An MRI is a diagnostic test that uses a strong electromagnetic field to produce images of the human body. MRI safety testing has shown that the WATCHMAN Implant is “MRI conditional” and that WATCHMAN patients may safely have an MRI scan under certain conditions listed on the WATCHMAN Implant Card.

Important: Before getting an MRI, be sure to tell the doctor and the MRI technologist that you have a WATCHMAN Implant and show them you WATCHMAN Implant Card so they can take all necessary safety precautions. 

Understanding the importance of medications

After your WATCHMAN procedure, it’s extremely important to take the medications prescribed by your doctor at the recommended time. These include: blood thinners, clopidogrel, and aspirin. If you stop taking these medications or change their dosage before your doctor instructs you to do so, it may increase your chances of blood clot formation, subsequent stroke, or even death. Talk to your doctor before stopping your medications or changing the dosage.

Talk to your doctor

If you need medical or dental treatment, tell your dentist or doctor you have a WATCHMAN Implant and show them your WATCHMAN Implant Card. Your care team can contact your heart specialist and work together to find a treatment that works best for you.
