These questions include answers about pulmonary artery (PA) pressure sensors, cardiac resynchronization therapy pacemakers (CRT-Ps), cardiac resynchronization therapy implantable cardioverter defibrillators (CRT-Ds), remote monitoring and left ventricular assist devices (LVADs).

  • What does the pacing pulse from a CRT-P feel like?
    The electrical pulse of a cardiac resynchronization therapy pacemaker (CRT-P) is very small. Most people cannot feel it at all. If you do feel a pacing pulse, your doctor may change the settings to make you more comfortable.
  • Will a CRT-P or CRT-D be noticeable under my skin?
    Your device will likely be noticeable under your skin. If you are worried about how this might look, talk to your doctor. In some cases, the device can be located somewhere that will be less noticeable.
  • How often does the CRT-D deliver pacing?
    The purpose of the CRT-D is to deliver pacing when the lower chambers of the heart are not beating in synchrony. For the most part, this pacing is constant.
  • Do the shocks from a CRT-D hurt?
    People perceive the shocks from a CRT-D differently. Patients requiring a life-saving shock may experience it as uncomfortable; although unpleasant, such a shock means that your device has responded to a dangerous rhythm, and it may have just saved your life.
  • How will an LVAD affect my daily routine?

    Most patients describe a marked improvement in their quality of life following VAD implantation,1 yet it is a big change for both recipients and caregivers. There is much to learn and it will take some time for you both to adjust. Today’s LVADs are lightweight and smaller than earlier models, so you’ll most likely be able to move around fairly easily, get certain kinds of moderate exercise and enjoy intimacy with your spouse or partner.2

  • How long can the HeartMate 3™ LVAD or the HeartMate II™ LVAD be used?

    Recipients have lived for years with the HeartMate II™ LVAD; in fact, some are living over 10 years post implant.3 The HeartMate 3™ LVAD is currently indicated for providing short- and long-term mechanical circulatory support (e.g., as bridge to transplant or myocardial recovery, or destination therapy) in patients with advanced refractory left ventricular heart failure.

  • Is it safe to engage in sexual activity after receiving an implanted cardiac device?

    Other than during your hospital stay and recovery period after receiving treatment, your sex life should not be affected. However, be sure to follow your doctor’s advice regarding the precautions to be taken and when to return to any kind of physical activity. LVADs are not to be used in pregnant women or in women likely to become pregnant.

  • If I have a CRT-P or CRT-D, is it safe to use a cell phone?
    Cellular phones send electromagnetic signals, so they can interfere with your device’s function if you do not take precautions. To minimize risk of problems, keep your cellular phone away from the immediate area of your implant, and hold it to the ear farthest from the implant when making calls. Read more about your device and electromagnetic interference (EMI).
  • Will an iPod music player or other portable multimedia devices cause problems with my pacemaker?
    There is no indication that compact multimedia players, such as iPod products or mp3 players, interfere with Abbott cardiac devices. Some limited data suggests that during device evaluation in the hospital or in a clinic, these players can disrupt communication between the pacemaker and the programmer wand within approximately 12 inches of either device. Again, this interference is only observed when the multimedia player is within 12 inches of the implanted pacemaker and the programmer’s telemetry wand. Although there is no evidence that carrying a multimedia player device affects a pacemaker’s ability to provide therapy, be sure to carry your player on the opposite side of your body from your implant. Read more about your device and electromagnetic interference (EMI).
  • What medical procedures can I safely receive with a CRT-P, CRT-D or PA sensor?

    These procedures carry no known risk to implantable devices: 

    • Acupuncture with no electrical stimulus
    • Bone density scan
    • CT scan
    • Dental drilling and ultrasonic scalers
    • Diagnostic X-ray
    • Electrocardiogram
    • External counter pulsation 
    • Fluoroscopy
    • Mammography
    • Positron Emission Tomography (PET)
    • Ultrasound, diagnostic

  • I have a patient notifier to alert me of changes in the function of my CRT-P or CRT-D. Do I still need to keep my follow-up appointments?
    Yes. The patient notifier feature helps to assess the mechanical function of the pacemaker and, to some degree, the device’s interaction with your heart. It is an extra feature that lets you and your doctor know whether your device needs attention between regularly scheduled appointments. It is important to go to your appointments to periodically assess your device’s function, to make sure it is working correctly, and, at times, to adjust the settings to achieve desired results. Likewise, your doctor needs to make sure that no problems are developing that are otherwise undetectable, but that may impact the effectiveness of pacing therapy.
  • What precautions do I need to take if I have a pulmonary artery (PA) pressure sensor?

    Most of the things you handle or work around every day are not going to affect your PA sensor. It will not set off airport security. Electromagnetic interference (EMI) from theft detection and airport security systems could make it difficult to take sensor readings. However, it is highly unlikely that you would be taking readings when you are close to these systems. Electric blankets or waterbeds could cause interference. If you have a waterbed or electric blanket, take your reading in another room. If you get a high PA pressure reading while traveling, your doctor may contact you and may change your medication or suggest that you see a local doctor.


  • What general things should I keep in mind with an LVAD?

    Ask your healthcare provider about touching electronic equipment, such as TVs and computer monitors. These have strong static electricity that can damage the electrical parts of the pump, causing it to stop.

    Tell your dentist and other doctors that you have an LVAD. Ask your doctor if you should take antibiotics before and after any dental work or invasive procedure to prevent possible infections.

    Do not have magnetic resonance imaging, also called MRI. MRI uses large magnets that could cause you injury and could cause the pump to stop.

  • How long do the batteries of the HeartMate 3 LVAD or the HeartMate II LVAD last?
    The latest generation of batteries used to support LVADs may last between 12 and 18 hours on a single charge.
  • What risks are associated with the HeartMate II LVAD and the HeartMate 3 LVAD?

    HeartMate 3 and HeartMate II LVAS Adverse Events:

    Adverse events that may be associated with the use of the HeartMate 3 or HeartMate II Left Ventricular Assist System are listed below: death, bleeding, cardiac arrhythmia, localized infection, right heart failure, respiratory failure, device malfunctions, driveline infection, renal dysfunction, sepsis, stroke, other neurological event (not stroke-related), hepatic dysfunction, psychiatric episode, venous thromboembolism, hypertension, arterial non-central nervous system (CNS), thromboembolism, pericardial fluid collection, pump pocket or pseudo pocket infection, myocardial infarction, wound dehiscence, hemolysis (not associated with suspected device thrombosis) and possible pump thrombosis.

    Please consult an advanced heart failure center or the website for a complete list of risks.

  • Will I be able to drive after receiving an implanted cardiac device?
    There is typically a period of time that needs to pass before being considered for driving privileges. Talk with your doctor before you start driving again. In some states and countries, there are legal restrictions on driving after a procedure, so check with your local authorities. Read more about living with your treatment
  • How will an LVAD affect my daily routine?

    LVADs are designed to restore blood flow throughout your body, restoring oxygen and nutrients to vital organs and tissues. This can make you feel better overall—less light-headed, less tired and less short of breath. Many LVAD recipients are able to resume most of their normal activities with few exceptions.*

    *Your advanced heart failure doctor will guide you on which activities you may need to avoid as an LVAD recipient. This includes contact sports, swimming and water sports since some components of the system are outside of the body and cannot be submerged in water.


  • Can I shower with an LVAD? How about taking a bath or swimming?
    Once the surgery site has healed, you may be allowed to shower. Because LVAD system components are not waterproof, you will need to protect the external parts of the system from water with a specially designed shower kit. Ask your healthcare provider for more specific instructions on showering. Swimming and taking a bath are not allowed with a LVAD because some components of the system are outside of the body and cannot be submerged in water.
  • Can I exercise with an LVAD?
    Physical exercise is essential to help prevent the unhealthy effects of bed rest and inactivity. Activity restrictions include swimming, contact sports or jumping activities. Your physician can discuss exercise goals and guidelines with you.
  • Will airport, courtroom or other security equipment interfere with my CRT-P or CRT-D?

    The amount of metal used in Abbott implanted medical devices is very small. It is usually not enough to set off metal detectors; however, if it does, simply show security personnel your patient identification card. If they use a handheld wand, ask them to pass quickly over your device. Metal detectors will not hurt your device. Yet, be sure to move through the detector at a normal speed and do not stay close to it for very long.
