Cardiac Resynchronization Therapy (CRT)

Cardiac resynchronization therapy (CRT) involves the implantation of a pacemaker, an electronic device used to treat congestive heart failure by stimulating the left and right lower chambers of the heart to beat appropriately and efficiently. The procedure to place the pacemaker involves a small incision made in the chest, above the collarbone.

Benefits

1.    Alleviates the symptoms of congestive heart failure, which is when the heart beats more weakly than normal, preventing adequate blood from being pumped to the different parts of the body. The pacemaker will help the lower chamber of the hearts beat more efficiently in rhythm with each other.

2.    Improves survival, quality of life, heart function, and the ability to exercise.

3.    Reduces hospital stays in patients with severe congestive heart failure

There are two types of pacemakers that can improve heart function and blood circulation:

1.    A regular cardiac resynchronization therapy pacemaker or CRT-P.

2.    A cardiac resynchronization therapy defibrillator, or CRT-D, can detect when an arrhythmia is life-threatening and automatically shock the heart back into a normal rhythm. Doctors normally recommend the cardiac resynchronization therapy defibrillator (CRT-D), but the final decision on the appropriate device will depend on the individual patient.

  1. Bleeding or hematoma, and infection where the cardiac resynchronization therapy (CRT) device was implanted.
  2. Allergic reaction to the medications used during the procedure.
  3. Damage to blood vessels.
  4. Collapsed lung.
  5. Bleeding in the pericardium.
  6. Stroke, heart attack, or other serious complications, which are uncommon.
  7. Death (rare).
 
Let your doctor know if you develop problems, such as:
  1. Bleeding, swelling, or increased pain at the implantation site
  2. Fever
  3. Dizziness or fainting
  4. Chest pain
  5. Difficulty breathing
