About DOR procedure

This information is intended for general information only and should not be considered as medical advice on the part of Any decision on medical treatments, after-care or recovery should be done solely upon proper consultation and advice of a qualified physician.

What is the Dor Procedure?
The DOR procedure, also known as Endoventricular Circular Patch Plasty (EVCPP), is a heart reconstructive surgical procedure that is performed to treat an aneurysm that forms after a heart attack.

During the DOR procedure, the left ventricle is cut to expose the damaged area. The scarred aneurysm is tied with a looped stitch which is used to shrink it. The left ventricle is restored to its normal shape and size after the DOR procedure. The DOR procedure enhances ejection fraction and reduces the Left Ventricular End Systolic Volume Index (LVESVI). Chest pain and other symptoms are reduced and the pumping ability of the heart is improved.

The DOR procedure is an open-heart surgery. Therefore, if required, the surgeon may perform a coronary artery bypass graft (CABG) surgery or a valve repair surgery in addition to the DOR procedure.

How is the DOR Procedure Performed?

  • The DOR procedure is usually performed after coronary artery bypass graft surgery.
  • A small incision is made in the left ventricle to locate the position of the scarred aneurysm.
  • A couple or more circular stitches are made around the edge of the aneurysm that separates it from the rest of the tissues.
  • The stitches are tied together to separate it completely.
  • Sometimes a part of the scarred aneurysm is removed before the stitches are tied together.
  • If the amount of scarred tissue is too large and the standard stitches are inadequate, a Dacron patch is placed.
  • The left ventricle is closed with stitches after the DOR procedure.

How to Prepare for the DOR Procedure?
  • The patient may be required to take certain medication prescribed by the surgeon.
  • Certain medication that the patient is taking may be stopped two weeks before the surgery.
  • Some surgeons may instruct patients to shower using an antiseptic skin cleanser before the surgery.
  • The patient should not eat or drink anything for 6 to 8 hours before the surgery.
  • The patient can take medication with a small sip of water.

The patient needs to undergo some tests such as the following:
  • MRI
  • PET
  • Echocardiogram
  • Electrocardiogram
  • Routine blood tests
  • Chest X-ray

Duration of procedure/surgery : The DOR procedure takes approximately 20 to 30 minutes, but it is part of an open heart operation, which usually takes 3 to 4 hour.

Days admitted : Approximately 8 days

Anesthesia : General anesthesia

Recovery : - The patient is placed on an anti-coagulant to decrease the risk of blood clots.
- During hospitalization, the patient will undergo cardiac rehabilitation to help in recovery.
- Some patients require an Implantable Cardioverter-Defibrillator (ICD) to treat a severe form of abnormal heart rhythm.
- The patient needs to follow the specific guidelines set by the doctor.

Risks : - Infection
- Blood clots
- Breathing difficulty
- Blood loss
- Heart attack
- Chest wound infection

After care : - The patient should follow a 2,000 mg sodium diet.
- Fluids should be limited to 8 cups or less in a day.
