Can You Have a Watchman and a Pacemaker? A Guide to Combination Therapy
The answer is yes, you can have a Watchman device and a pacemaker. This combination therapy addresses two distinct heart conditions: atrial fibrillation (AFib) and bradycardia (slow heart rate), respectively.
Understanding Atrial Fibrillation (AFib) and Stroke Risk
Atrial fibrillation (AFib) is a common heart rhythm disorder characterized by rapid and irregular heartbeats. This irregularity can lead to blood clots forming in the left atrial appendage (LAA), a pouch-like structure in the heart. If a clot breaks loose, it can travel to the brain, causing a stroke. The primary risk associated with AFib is an increased likelihood of stroke.
The Watchman Device: A Stroke Risk Reducer
The Watchman device is a small, permanently implanted device designed to close off the left atrial appendage. By sealing off this area, it prevents blood clots from forming and potentially causing a stroke. It’s an alternative to long-term blood thinners for patients with non-valvular AFib.
- Implantation is minimally invasive, typically performed through a catheter inserted into a blood vessel in the groin.
- The device provides long-term stroke risk reduction without the need for chronic blood thinner medication in many cases.
- Patients usually take blood thinners for a short period after implantation to allow tissue to grow over the device.
Pacemakers: Regulating Heart Rate
A pacemaker is a small, battery-powered device implanted under the skin, usually near the collarbone. It sends electrical signals to the heart to regulate the heart rate, particularly when the heart beats too slowly (bradycardia) or irregularly.
- Pacemakers consist of a pulse generator and one or more leads that are threaded through blood vessels to the heart.
- They are essential for individuals whose hearts can’t maintain an adequate rhythm on their own.
- Modern pacemakers are sophisticated and can adjust their pacing rate based on the patient’s activity level.
The Overlap: When Both Devices Are Needed
Sometimes, individuals may have both AFib and bradycardia. AFib increases stroke risk, requiring a solution like the Watchman. Bradycardia necessitates a pacemaker to maintain a healthy heart rate. Therefore, patients can absolutely need and safely receive both devices.
Why Might Someone Need Both?
The need for both a Watchman and a pacemaker can arise from several situations:
- A patient is diagnosed with AFib and is not a good candidate for long-term blood thinners due to bleeding risk, lifestyle factors, or other medical conditions. They would receive the Watchman to reduce stroke risk. Separately, if they also have a slow heart rate (bradycardia), a pacemaker is needed to maintain a normal heart rhythm.
- A patient already has a pacemaker for bradycardia and is subsequently diagnosed with AFib. If stroke risk is deemed significant and blood thinners are not ideal, a Watchman device may be considered.
- AFib treatments, such as certain medications or ablation procedures, can sometimes affect the heart’s natural pacing system, potentially leading to the need for a pacemaker. If the patient has AFib with a high stroke risk, the Watchman can still be implanted.
Implantation Considerations and Safety
The implantation of both devices requires careful consideration and coordination between the cardiologist and electrophysiologist. While it is relatively uncommon to have both procedures performed at the same time, it is possible to implant them sequentially with appropriate planning.
- Careful consideration of the patient’s overall health, medications, and other medical conditions is crucial.
- Imaging studies, such as echocardiograms, are used to assess the heart’s structure and function.
- Post-implantation monitoring is essential to ensure both devices are functioning correctly and to manage any potential complications.
Potential Risks and Complications
As with any medical procedure, there are potential risks associated with both Watchman and pacemaker implantation, although the risks are generally low.
- Watchman: Bleeding, blood clots, device migration, and pericardial effusion (fluid around the heart).
- Pacemaker: Infection, bleeding, lead dislodgement, and pneumothorax (collapsed lung).
It’s important to remember that these risks are relatively low, and the benefits of reducing stroke risk and improving heart rhythm often outweigh the potential complications.
Benefits of Combination Therapy
The combination of a Watchman and a pacemaker offers significant benefits for eligible patients:
- Reduced risk of stroke in patients with AFib.
- Improved heart rate and rhythm regulation.
- Potential avoidance or reduction of long-term blood thinner use.
- Improved quality of life and overall well-being.
Living with Both Devices
Patients with both a Watchman and a pacemaker can typically live active and fulfilling lives. Regular follow-up appointments with their cardiologist and electrophysiologist are essential to monitor device function and address any concerns. Patients can lead near-normal lives, though heavy exercise will be considered alongside their individual case.

Conclusion
Can You Have a Watchman and a Pacemaker? Yes. The combination of a Watchman device and a pacemaker is a viable and often beneficial treatment strategy for individuals with both AFib and bradycardia. Careful patient selection, thorough pre-operative evaluation, and close post-operative monitoring are essential for optimizing outcomes and ensuring patient safety. The ability to address both stroke risk and heart rhythm issues offers a significant improvement in the quality of life for many patients.
Frequently Asked Questions (FAQs)
What exactly is the Watchman device made of?
The Watchman device consists of a self-expanding frame made of nitinol (a nickel-titanium alloy) and a permeable fabric covering made of polyethylene terephthalate (PET). These materials are biocompatible and designed to integrate into the heart tissue over time.
How long does the Watchman procedure take?
The Watchman implantation procedure typically takes 1 to 2 hours. Patients usually stay in the hospital overnight for observation.
Will I need to take blood thinners after getting a Watchman?
Yes, you typically need to take blood thinners for a short period, usually around 45 days, after Watchman implantation. This allows the tissue to grow over the device and create a complete seal of the left atrial appendage. After that, your doctor will assess whether you can switch to aspirin or another antiplatelet medication.
How often do I need to see my doctor after getting a Watchman?
Follow-up appointments are typically scheduled at 1 month, 6 months, and 12 months after the Watchman implantation. After the first year, you will likely have annual checkups. These appointments include echocardiograms to ensure the device is functioning correctly.
Can I travel with a Watchman device?
Yes, you can travel with a Watchman device. Because it is not electronic, it will not trigger metal detectors at airports, and no special precautions are needed.
How long do pacemakers last?
The battery life of a pacemaker typically ranges from 5 to 15 years, depending on how frequently it’s pacing and the specific model. Your doctor will monitor the battery life during routine checkups and will replace the pulse generator when needed.
Is it possible to have an MRI with a Watchman or a pacemaker?
Yes, but it depends on the specific model of both the Watchman and the pacemaker. Newer pacemakers and the Watchman are often MRI-conditional, meaning they are safe for MRI scans under certain conditions. It is crucial to inform your doctor and the MRI technician that you have these devices so that they can take the necessary precautions.
Are there any lifestyle restrictions with a Watchman or a pacemaker?
Most patients can return to their normal activities after a recovery period. With a Watchman, strenuous activities that could increase bleeding risk may be limited temporarily. With a pacemaker, activities involving strong magnetic fields or direct impact to the device’s location should be avoided. Your doctor will provide specific guidance.
What are the alternatives to a Watchman device for stroke risk reduction in AFib?
The main alternative to the Watchman device is long-term blood thinner medication, such as warfarin or direct oral anticoagulants (DOACs). The choice between the Watchman and blood thinners depends on individual risk factors, lifestyle, and preferences.
What if my pacemaker malfunctions?
If your pacemaker malfunctions, you may experience symptoms such as dizziness, fatigue, shortness of breath, or palpitations. Contact your doctor immediately if you suspect a problem with your pacemaker.
How do doctors decide who is a good candidate for a Watchman and a Pacemaker?
The decision to implant Can You Have a Watchman and a Pacemaker? hinges on a patient having both AFib (and thus a need to lower stroke risk), and bradycardia (requiring a pacemaker to regulate heart rate). Factors such as bleeding risk, medication tolerance, and overall health are carefully considered to determine candidacy.
Is it better to get the Watchman or Pacemaker implanted first if both are needed?
The order of implanting the Watchman and pacemaker depends on the specific clinical situation. If the bradycardia is more immediately life-threatening, the pacemaker might be implanted first. If stroke risk is very high and imminent, then Watchman implantation might be prioritized. There is not one definitive answer; it depends on the individual’s unique heart condition.
