Heart Assist System Implantation

(Ventricular Assist Device; VAD)

by Amy Scholten, MPH

Definition

A heart assist system implantation is a procedure to install a mechanical heart pump. The heart pump is also called a ventricular assist device (VAD).

Left Ventricular Assist Device

Reasons for Procedure

A VAD helps the heart pump blood. It is used for people with heart failure. Heart failure is when the heart is too weak to pump the blood the body needs.

A VAD may be used for those who:

Have short-term heart failure—and need help until the heart gets healthy
Are waiting for a heart transplant
Cannot get a heart transplant
Have not been helped by other treatment
Have a low risk of surviving 1 year

Possible Complications

Problems are rare, but all procedures have some risk. The doctor will go over some problems that could happen, such as:

Excess bleeding
Problems from anesthesia
Infection
Damage to other organs or structures

Things that raise the risk of problems are:

Smoking
Drinking alcohol
Long-term diseases such as diabetes or obesity

What to Expect

Prior to Procedure

The surgical team may meet with you to talk about:

Anesthesia options
Any allergies you may have
Current medicines, herbs, and supplements that you take and whether you need to stop taking them before surgery
Fasting before surgery, such as avoiding food or drink after midnight the night before
Whether you need a ride to and from surgery
Tests that will need to be done before surgery

Anesthesia

The doctor will give general anesthesia. You will be asleep.

Description of the Procedure

An incision will be made down the length of the breastbone. The breastbone will then be opened. A machine will replace heart and lung function during the procedure. The VAD will be placed into a pocket inside the belly wall. Tubes will be sewn to the heart. Tubes may also be sewn to the aorta. This will depend on the type of device needed. The incision will be closed with stitches or staples. A bandage will be placed over the site.

How Long Will It Take?

About 4 to 8 hours

Will It Hurt?

Pain and swelling are common in the first few weeks. Medicines and home care help.

Average Hospital Stay

2 to 5 days in the ICU
2 to 4 weeks in a hospital room

Postoperative Care

At the Hospital

During your stay, the hospital staff will take steps to lower your risk of infection, such as:

Washing their hands
Wearing gloves or masks
Keeping your incisions covered

There are also steps you can take to lower your risk of infection, such as:

Washing your hands often and reminding visitors and staff to do the same
Reminding staff to wear gloves or masks
Not letting others touch your incisions

At Home

Recovery takes about a few weeks. Some activities will be limited during that time.

Call Your Doctor

Call your doctor if you have:

Fever or chills
Redness, swelling, pain, bleeding, or discharge from the wound
One-sided weakness, blurry vision, or inability to talk
A cold, pale or blue, numb, or painful hand or foot
Coughing, problems breathing, or chest pain
Lasting nausea or vomiting
Problems passing urine or stool (poop)
Redness or swelling in legs

If you think you have an emergency, call for medical help right away.
