Ventricular Assist Devices (VADs)

Ventricular assist devices, or VADs, are used for the treatment of heart failure. Also known as heart pumps, VADs are mechanical pumping devices designed to help the heart pump more blood. They work by taking blood from the heart and pumping it to the rest of the body, thus taking the burden off the heart.

Types of Ventricular Assist Devices

  • Left ventricular assist devices (LVADs)
  • Biventricular assist devices (bi-VADs)
  • Right ventricular assist devices (RVADs)
  • Percutaneous ventricular assist devices (Impella and TandemHeart)

Impella and TandemHeart Devices

Percutaneous VADs, including Impella or TandemHeart, are designed to help support a heart until it can be repaired. They can be inserted in our cardiac catheterization lab, and keep the heart beating until lifesaving therapy, such as angioplasty or stenting, can be performed.

Who Is a Candidate for a VAD?

Ventricular assist devices are most commonly used in patients awaiting a heart transplant, to support the heart until a donor heart is available - a process known as “bridge to transplant.”

Research has also shown that for many patients, VADs can be used for successful long-term treatment in themselves. For patients who are not candidates for heart transplant, the ventricular assist device is considered a “destination therapy,” or a permanent solution for a failing heart.

Ventricular assist devices may also be used in patients with certain types of heart failure with the goal of helping the heart to heal itself. The VAD is implanted temporarily to support the heart while it recovers, and then is removed.

How VADs Are Implanted

Most ventricular assist devices (LVADs, RVADs and bi-VADs) are implanted during open heart surgery through an incision in the chest. The blood is rerouted to a heart-lung machine to be pumped and oxygenated. The surgeon forms a pocket for the VAD in the abdominal wall, and a tube is used to channel blood from the ventricle to the device.

Another tube is used to connect the pump to the aorta. Once the pump begins to work and support the heart, the patient is removed from the heart-lung machine and the incision is closed.

Percutaneous VADs (Impella and TandemHeart) are inserted with a catheter through a blood vessel and do not require open heart surgery.

Why Choose UC San Diego Health System?

The Joint Commission approved UC San Diego Health System’s Disease-Specific Care (DSC) Certification for Ventricular Assist Device (VAD). Fewer than 110 facilities are approved for VAD destination therapy. UC San Diego Health System is one of only two San Diego-based systems and eight California-based systems offering this option.
