An artificial heart is a medical device that helps a failing heart. It gives patients with severe heart problems a second chance. This device is a big step forward in treating heart failure, helping those waiting for a transplant or not eligible for one.
An artificial heart, or mechanical heart, works like a real heart. It has a pump, valves, and a power source. The pump moves blood, the valves keep it flowing right, and the power source runs the pump.
The parts work together to support or replace the heart’s function. Thanks to technology, these hearts are getting better, lasting longer, and working better.
Artificial hearts are made to act like a real heart, but they’re different. They need a power source, which can make moving harder. They also face issues like infections and breakdowns.
Even with these challenges, artificial hearts are a key option for severe heart failure. New tech is making these hearts better, aiming for better results for patients.
Artificial hearts come in different types to meet various patient needs. They are developed to tackle the complex nature of heart failure. We’ll look at Total Artificial Hearts (TAHs), Ventricular Assist Devices (VADs), and Biventricular Assist Devices (BiVADs).
Total Artificial Hearts replace the whole heart, including both ventricles and atria. They’re for patients with severe heart failure who can’t get a transplant or are waiting. The SynCardia Total Artificial Heart is a well-known model. It’s been used for decades and works by being pneumatically driven.
Ventricular Assist Devices are pumps that help the ventricles pump blood better. They’re for patients with left, right, or both ventricular failures. Left Ventricular Assist Devices (LVADs) are the most common, supporting the left ventricle.
They’re often used in patients waiting for a transplant or as a long-term solution for those not eligible for a transplant.
Biventricular Assist Devices support both the left and right ventricles. They’re for patients with biventricular failure, where both sides of the heart aren’t working well. These devices are key for patients needing full cardiac support.
By helping both ventricles, BiVADs ensure proper blood flow. They’re a vital step towards heart transplantation.
Each artificial heart type has its own use, benefits, and challenges. The right device depends on the patient’s heart condition and other factors. As technology improves, we’ll see more advanced artificial hearts.

Putting in an artificial heart is a complex surgery that has gotten better over time. It needs a team of experts, like heart surgeons, anesthesiologists, and perfusionists. They work together to help patients get better.
Choosing the right patients for this surgery is very important. Doctors look at the patient’s health history, current condition, and how well they might recover. They check how bad the heart failure is, if there are other serious health issues, and the patient’s overall health and mental state. They use tools like echocardiography and cardiac catheterization to check the patient’s health and decide if they can have the surgery.
The surgery to put in an artificial heart is long and detailed. First, the patient is put on a machine that keeps blood flowing and oxygen levels up while the heart is stopped. Then, the team removes the patient’s heart, being careful to keep the blood vessels and tissue for the artificial heart. The artificial heart is then put in, and the blood vessels are connected to it. The team must be very careful to make sure the device fits and works right.
After surgery, patients go to the ICU for close watch and care. The first days are very important for managing pain, stopping infections, and making sure the artificial heart works well. The team keeps a close eye on the patient’s health and adjusts the device as needed. They also help the patient and their family with any worries and support them through recovery.
As patients get better, they start to breathe on their own and start their recovery. The medical team keeps checking on them and makes changes to their care as needed to help them get the best results.
The survival rates of artificial heart technology are key for patients with severe heart failure. As we improve this field, knowing these stats is vital for doctors and patients.
