Off-Pump Coronary Artery Bypass Surgery (OPCAB)

Coronary artery bypass grafting (CABG) is one of the most common surgical procedures for treating blocked or narrowed coronary arteries. It restores blood flow to the heart muscle, improving its function and reducing symptoms. With advancements in medical technology, off-pump coronary artery bypass grafting (OPCAB) has become a modern technique used in this procedure, offering significant advantages over traditional surgery.

This procedure is performed for patients with severe blockage or narrowing of the coronary arteries that limit blood flow to the heart muscle. Common indications include:

• Complete blockage of a coronary artery due to atherosclerosis or fat accumulation. 

• Multiple blockages affecting more than one coronary artery. 

• Failure of medications or other treatments, such as stents or catheterization, to relieve symptoms. 

• Unstable angina (severe chest pain that persists despite treatment). 

• High risk of heart attack, where bypass surgery helps reduce the risk of a life-threatening heart attack.

Coronary artery bypass grafting (CABG) is a surgical procedure performed to treat blockages in the coronary arteries that supply blood to the heart muscle. It is performed using a heart-lung bypass machine. This machine supports the patient during surgery by compensating for the heart and lung function, allowing the surgeon to operate on the still heart precisely and safely.

1. Patient preparation: General anesthesia is administered, and vital signs (heart rate, blood pressure, oxygen levels) are monitored. 

2. Chest incision: A midline incision (sternotomy) is made to access the heart, then the sternum is separated to open the rib cage. 

3. Heart-lung machine connection: Blood vessels are connected to the machine via special tubes, which circulate blood, remove carbon dioxide, and add oxygen, thus maintaining blood flow to the body during cardiac stoppage.

4. Stopping the heart (cardioplegia): A cold solution is used to temporarily stop the heart, allowing the surgeon to work on a still heart.

5. Selecting a healthy blood vessel: Usually, a blood vessel taken from the leg or chest (internal mammary artery or saphenous vein) is used. 

6. Bypass grafting: The blood vessel is connected to the aorta on one side and after the blocked coronary artery section on the other side, restoring normal blood flow to the heart muscle. 

7. Restarting the heart: The heart gradually resumes beating. The use of the heart-lung machine is discontinued when the heart regains its normal function.

8. Closing the chest: The sternum is closed with wires, and tissues are sutured. Drainage tubes are then connected to remove excess fluid from the chest area.

• Compensating for heart function: The device pumps blood to the body.

• Compensating for lung function: It removes carbon dioxide and adds oxygen to the blood.

• Maintaining stable blood circulation: Ensures that organs receive oxygen during surgery.

• Blood clots 

• Bleeding (due to anticoagulants) 

• Lung or kidney complications 

• Infections 

The off-pump coronary artery bypass grafting (OPCAB) or a beating heart surgery is a modern technique performed without using a heart-lung machine. The heart continues beating during the procedure. Its advantages include:

• No need to stop the heart: The procedure is performed while the heart is beating normally.

• Fewer complications (e.g., stroke, infections) than with the artificial heart-lung machine.

• Faster recovery compared to traditional surgery 

• The surgery is performed while the heart is still beating.

• The heart-lung machine is not used.

• It is considered less invasive, with faster recovery and fewer complications.

• It requires temporarily stopping the heart during surgery.

• The heart-lung machine is used to circulate the blood.

• It is often used in more complex cases.

Off-pump coronary artery bypass grafting offers several advantages compared to traditional surgery, such as

• Reduced complications (e.g., stroke, infections).

• Faster recovery and return to daily activities.

• Shorter procedure time as the surgery is less complicated, thanks to the lack of need for an artificial heart/lung machine.

• Suitable for the elderly and patients with chronic diseases.

No, the off-pump coronary artery bypass grafting (OPCAB) is not suitable for everyone.

• Patients with a single or limited blockage in the coronary arteries.

• Elderly patients who may not tolerate cardiac arrest.

• Patients requiring a less invasive procedure and a faster recovery.

• Complex or multiple blockages that require careful visualization.

• The presence of additional heart problems that require stabilizing the heart by stopping it using an artificial heart/lung machine.

• Patients suffering from aneurysms or severe arterial damage.

Beating-heart surgery takes less time than traditional open-heart surgery. Its duration ranges from 3 to 5 hours, depending on case complexity, the number of arteries that need grafting or repair, and the experience of the surgeon and medical team.

The success rate of off-pump coronary artery bypass grafting (OPCAB) exceeds 95% in mild and moderate cases. Expected outcomes include:

• Restoring normal blood flow to the heart muscle 

• Relief of symptoms (chest pain, shortness of breath) 

• Faster recovery than traditional surgery

• Fewer complications (strokes or bleeding)

• Rare blood clots, but possible in some cases.

• Incomplete grafting: due to the complexity of the blockages.

• Heart rhythm problems, such as a fast or slow heartbeat.

• Narrowing of the grafted artery if it does not heal properly.

• Swelling at the surgical site due to accumulated fluids

• Bleeding during or after surgery

• Infection at the site of the wound or inside the chest

• Temporary weakness of the heart muscle

• Following medical instructions 

• Proper wound care 

• Taking medications regularly

The cost of beating-heart surgery varies depending on several factors, including the surgeon's experience, the complexity of the patient's health condition, and the level of service provided by the hospital.

In general, the cost of beating-heart surgery in Egypt is much lower than in neighboring countries, while maintaining high-quality care.
