Cardiac Resynchronisation Therapy

What is an Cardiac Resynchronisation Therapy (CRT)?

Cardiac Resynchronisation Therapy (CRT) is a treatment for heart failure that uses a specialised device to improve the coordination of the heart’s lower chambers (ventricles). In some patients with heart failure, the ventricles do not beat in a coordinated way. This reduces the heart’s efficiency and can worsen symptoms such as shortness of breath and fatigue.

CRT works by restoring the normal, coordinated pumping action of the ventricles. This allows the heart to pump blood more efficiently and can improve symptoms and overall heart function. The device used for CRT is similar in size to a pacemaker and is implanted beneath the skin, usually below the collarbone.

What to expect before your procedure

Please note this booklet provides general information about your procedure. The hospital booking team will contact you prior to your procedure with personalised instructions specific to your medical history.

Before

Your Cardiologist may request a blood test.

You may be asked to stop taking some medications.

You are required to fast from midnight, or for at least 6–8 hours prior to your procedure.

If you are a diabetic, please contact us for specific instructions.

Please pack an overnight bag, as you will be required to stay overnight for observation.

On the day of your procedure

Make transport arrangements to and from the hospital as you won’t be able to drive after the procedure.

Arrive at the Hospital at least two hours prior to your procedure.

During the procedure

The procedure is performed in a Cardiac Catheterisation Laboratory.

You will receive anaesthetic during the procedure (as advised by your medical team).

A small incision is made, usually below the collarbone.

A device, similar in size to a pacemaker, is implanted under the skin.

Three leads (wires) are positioned in the heart using imaging guidance.

The leads monitor your heart rhythm and deliver small electrical impulses to restore coordinated ventricular contraction.

The incision is then closed.

Post procedure care & discharge information

You will be taken to a recovery area for observation and monitoring.

Once stable, you will be transferred to a patient room and monitored regularly.

You may be required to lie flat for approximately one hour to support healing at the incision site.

In most cases, your Cardiologist will be able to provide results on the day of your procedure.

A full report will be sent to your referring doctor.

Drink plenty of fluids to support recovery.

Do not participate in strenuous activities such as; sports, housework, heavy lifting etc for at least 2 days.
