Cardiac Resynchronization Therapy
WHAT YOU NEED TO KNOW:
Cardiac resynchronization therapy (CRT) is a procedure used to treat problems with how your heart beats. CRT is also called biventricular pacing. Your heart has 2 upper chambers, called atria, and 2 lower chambers, called ventricles. Your heartbeat is synchronized when all areas of your heart beat together properly. When the areas of your heart do not beat as they should, your heart cannot pump enough blood and oxygen to your body. You may have trouble breathing, tire easily, and have swelling in your legs and feet.
WHILE YOU ARE HERE:
Before your procedure:
- Informed consent is a legal document that explains the tests, treatments, or procedures that you may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered.
- An IV is a small tube placed in your vein that is used to give you medicine or liquids.
- General anesthesia will keep you asleep and free from pain during the procedure. You may get anesthesia through your IV. You may breathe it in through a mask or a tube placed down your throat. The tube may cause you to have a sore throat when you wake up.
During your procedure:
- A small incision is made over a vein near your neck. An x-ray may be used to help guide your healthcare provider during the procedure. An electrode catheter holding 3 leads will be inserted through the incision. The catheter and leads are guided into your heart. The catheter records the activity of your heart to help your healthcare provider decide where to place the leads. One lead is placed in your right atrium, one in your right ventricle, and one in your left ventricle.
- If any of the leads cannot be placed through your vein, they may be placed through your chest. Three or four small cuts are made on your left side, between your ribs. The leads are placed directly on your heart. Once the leads are placed, a pacemaker is secured under the skin on your chest. The pacemaker will help your ventricles beat together and beat correctly with your right atrium. Healthcare providers will close your cuts with stitches or medical glue.
After your procedure:
You will be taken to a room to rest until you are fully awake. Healthcare providers will monitor you closely for any problems. Do not get out of bed until your healthcare provider says it is okay. You may need an EKG, echo, or chest x-ray to check the placement of the leads in your heart. When your healthcare provider sees that you are okay, you will be taken to your hospital room.
- You may need a large chest incision if the leads cannot be placed through your vein or small cuts. You may get a wound infection, or an infection around the pacemaker implant. The activity of the pacemaker may make it hard for you to breathe at times. Your heart, blood vessels, and the area around them may be damaged. You may have abnormal heartbeats, and your heart may stop beating. Blood may collect around your heart, making it hard for your heart to beat. This can be life-threatening.
- The leads in your heart may move out of place. The leads may not be in the right position to synchronize your heartbeats. The pacemaker may not work properly. If you do not have CRT, your symptoms may worsen. You may have abnormal heartbeats that stop your heart. Your heart failure may get worse, and may become life-threatening.
