What are the Risks of Using HeartMate 3? Heart Device Saves Some, Raises Concerns for Others

What are the Risks of Using HeartMate 3? The HeartMate 3 is a revolutionary device that has given hope to many people with severe heart failure. It is a mechanical pump that is implanted in the heart to help it pump blood more effectively. However, like any medical device, it comes with potential risks. Here are some of the most common risks associated with using the HeartMate 3:

Stroke

One of the most serious risks of using the HeartMate 3 is stroke. The device can cause blood clots to form, which can then travel to the brain and cause a stroke. The risk of stroke is higher in people who have had a stroke in the past or who have other risk factors for stroke, such as high blood pressure or diabetes.

Bleeding

The HeartMate 3 can also cause bleeding, both internally and externally. Internal bleeding can occur if the device damages a blood vessel. External bleeding can occur if the device becomes dislodged or if the incision site where the device is implanted does not heal properly.

Infection

Infection is another serious risk of using any medical device, including the HeartMate 3. The device can become infected with bacteria, which can lead to serious complications, such as sepsis. The risk of infection is higher in people who have a weakened immune system or who have other medical conditions, such as diabetes.

Device malfunction

The HeartMate 3 is a complex device, and it is possible for it to malfunction. Malfunctions can be caused by a variety of factors, such as mechanical failure or electrical problems. If the device malfunctions, it may not be able to pump blood effectively, which can lead to heart failure or even death.

Right heart failure

The HeartMate 3 is designed to help the left ventricle of the heart pump blood. However, it can also put extra strain on the right ventricle. In some cases, this can lead to right heart failure.

Quality of life

 While the HeartMate 3 can improve quality of life for many people with heart failure, it is important to remember that it is a major surgery and recovery can be difficult. Some people may experience fatigue, pain, and other side effects after having the device implanted.

It is important to talk to your doctor about the risks and benefits of using the HeartMate 3 before making a decision about whether or not to get the device. Your doctor can help you weigh the risks and benefits in light of your individual medical condition.

Here are some additional things to keep in mind:

• The HeartMate 3 is a relatively new device, and long-term data on its safety and effectiveness is still limited.
• The FDA is continuing to monitor the safety of the HeartMate 3, and it is possible that new risks may be identified in the future.
• If you have any concerns about the HeartMate 3, be sure to talk to your doctor.

Recent Research Findings

Arvid Herrman, a 68-year-old Wisconsin farmer with severe heart failure, faced a life-or-death decision. A traditional heart transplant was out of the question due to his age and declining health. His only option: a potentially life-saving mechanical pump called the HeartMate 3, the only FDA-approved device of its kind. Herrman chose the pump, hoping for a few more years. Instead, it led to his death, according to a lawsuit filed by his daughter.

Alleged Defect and Tragic Outcome: The lawsuit claims a defect in the HeartMate 3’s locking mechanism prevented proper sealing, causing multiple strokes and ultimately Herrman’s demise. This wasn’t an isolated incident. Ramon Flores Sr. received the same device and suffered a similar fate, allegedly due to the same malfunction. His daughter questions why they weren’t informed about this potential danger.

Manufacturer’s Response: Thoratec, the device’s manufacturer (now owned by Abbott Laboratories), confirmed bent locking arms in both cases but couldn’t definitively link them to the deaths. Abbott denied liability in both lawsuits, settling Herrman’s case and contesting Flores’s. They maintain the HeartMate 3 is the safest LVAD yet and cite its approval by the FDA.

Red Flags in the Data: A closer look at the FDA’s Manufacturer and User Facility Device Experience (MAUDE) database reveals over 4,500 reports since 2017 where the HeartMate 3 may have been involved in patient deaths or serious injuries. In nearly 90% of these cases, Thoratec found no issue with the device. However, critics like former FDA officials Madris Kinard and Larry Kessler raise concerns. They believe the high number of death reports warrants further investigation and suggest the FDA might be missing crucial signals.

Challenges in Tracking Device Safety: MAUDE’s limitations make it difficult to gain a complete picture of any device’s safety profile. Reports can be inaccurate, incomplete, or missing altogether. This lack of transparency leaves patients and their families uninformed about potential risks. Even doctors struggle to use MAUDE effectively for patient counseling.

Systemic Issues: The HeartMate 3 isn’t the only device raising safety concerns. Dhruva, a cardiologist and expert in medical device safety, criticizes the overall weakness of postmarket surveillance for medical devices. He emphasizes the need for better data collection and analysis to identify and address safety problems promptly.

A Call for Action: Herrman and Flores’s tragedies highlight the need for greater transparency and accountability in the medical device industry. A more robust postmarket surveillance system, coupled with improved communication and education for patients and healthcare providers, is crucial to ensure the safety of these life-saving technologies.
