What is a Cardiac Resynchronization Therapy (CRT)?

Cardiac Resynchronization Therapy (CRT) is a treatment for heart failure that uses a special type of pacemaker to improve the timing of the heart's contractions. It helps the ventricles pump more efficiently and in sync.

What happens during a Cardiac Resynchronization Therapy (CRT)?

During CRT, the surgeon makes an incision and inserts lead into veins, guiding them to the heart. The leads are positioned in both the right and left ventricles and connected to a CRT device placed under the skin. The procedure typically lasts 2 to 4 hours.

Why would I need a Cardiac Resynchronization Therapy (CRT)?

You might need CRT if:

• You have moderate to severe heart failure with symptoms that are not controlled by medication.

• Your heart's ventricles do not beat in sync, reducing its efficiency.

• You have a specific type of electrical delay in the heart, such as left bundle branch block.

Who needs a Cardiac Resynchronization Therapy (CRT)?

CRT may be necessary for:

• Patients with chronic heart failure and reduced ejection fraction.

• Individuals with specific types of abnormal heart rhythms.

• Those who have not responded adequately to other heart failure treatments.

​

What are the risks of a Cardiac Resynchronization Therapy (CRT)?

• CRT involves some risks, including:

• Infection at the implantation site.

• Bleeding or bruising.

• Lead displacement or malfunction.

• Rarely, is damage to blood vessels or the heart.

It's important to note that these risks are rare and the benefits of the test typically outweigh the risks. Additionally, the test is performed under the supervision of trained medical professionals who are equipped to handle any complications that may arise. Your doctor will review your medical history and assess your overall health to determine whether the benefits of the test outweigh the risks for you. If you have concerns about the risks of a stress echocardiogram, discuss them with your doctor before the test.

How do I prepare for Cardiac Resynchronization Therapy (CRT)?

To prepare for CRT:

• Follow your doctor’s instructions, which may include fasting for several hours before the procedure.

• Inform your provider of any allergies and medications you are taking.

• Arrange for someone to drive you home after the procedure, as you may be sedated.

• Wear comfortable clothing and remove any jewelry or metal objects.
