Understanding the Difference Between Bypass and Open Heart Surgery

One major difference between bypass and open-heart surgery is:

Open-heart surgery involves cutting the chest to reach the heart directly, and this surgery works on different parts of your heart, like muscles, valves, and arteries. Sometimes, the heart itself may stay closed, but the surgery still takes place inside your chest.

In bypass surgery, the doctor takes a healthy blood vessel from your chest or leg and connects it to the artery in the heart that has a blockage, creating a new path for blood to flow. It can be done in two ways: either through open-heart surgery or using less invasive techniques that require smaller cuts. Both surgeries have their advantages and benefits, and the choice depends on your condition.

What is Heart Bypass Surgery?

Heart bypass surgery is an operation in which doctors open your chest to reach your heart, and it is done to create a new path for blood to flow around blocked and narrowed arteries. In this, the surgeon takes a healthy blood vessel from another part of your body and connects it between the aorta and a point beyond the blockage in your artery.

Usually, one of the blood vessels used is an artery from your chest, called the internal mammary artery. Other vessels can come from your leg or your arm.

You may need a single bypass if one artery is blocked, or a double bypass if two arteries are blocked. If three arteries are blocked, you will need a triple bypass, and if four arteries are blocked, you will need a quadruple bypass.

What are the Common Conditions Treated by Heart Bypass Surgery?

The most common conditions are serious heart artery disease. People who may need CABG often have one or more of these problems:

• Severe Blockages in the Heart Arteries

When several blood vessels in your heart are badly blocked, the heart muscle doesn’t get enough oxygen-rich blood.

• Angioplasty Didn’t Work

When other treatments, such as placing a stent or undergoing angioplasty, fail and are not suitable for the patient.

• Major Block in the Left Main Artery

When the main artery that supplies blood to the left side of your heart is narrowed or blocked.

• Severe Chest Pain (Angina)

Ongoing chest pain and discomfort that doesn’t get better with medicines and other treatments.

Surgical Technique for Heart Bypass Surgery

The open-heart method is still common and often preferred. However, knowing the difference between bypass and open-heart surgery shows that some patients may benefit more from less invasive options.

Traditional Bypass Surgery

In a traditional bypass surgery, the surgeon makes a large cut in your chest and temporarily stops the heart. To reach the heart, the surgeon cuts the sternum in half and gently spreads it apart. Tubes are then placed in your heart so that a heart-lung machine can keep blood and oxygen flowing through the body while the surgery is being done.

Minimally Invasive Bypass Surgery

While the open-heart method is still common and often preferred, newer and less invasive techniques are also available to treat blocked heart arteries, including:

• Off-pump bypass surgery: It is done while your heart is still beating, and no heart-lung machine is used.
• Keyhole bypass surgery: It is performed through a few small cuts instead of one large cut.
• Robotic bypass surgery: Performed with the help of a highly accurate robotic device controlled by the surgeon.
• Hybrid coronary revascularization: It is a mix of two methods, where some blockages are treated with stents and others are bypassed through surgery.

Recovery Tips After Heart Bypass Surgery

‣ You Should Follow Your Doctor’s Advice

• Take medicines as prescribed by your doctor.

• Contact your doctor if you notice infection signs and unusual symptoms.

Understanding Open-Heart Surgery

Open-heart surgery involves cutting open your chest and performing surgery on the heart’s muscles, valves, and arteries. Caring for yourself and your incision after surgery can help minimize some risks. It’s also useful to know the difference between bypass and open-heart surgery.

What is Open-Heart Surgery?

Open-heart surgery is a type of operation to treat heart problems by opening your chest and operating directly on the heart.

In this surgery, the doctor cuts through the breastbone and gently spreads the ribs apart to reach the heart. It is used to treat several heart problems, such as:

• Heart failure
• Problems with the heart valve.
• Irregular heartbeats (arrhythmias).
• Swelling and bulging of blood vessels (aneurysms).
• Blocked heart arteries.

When is Open-Heart Surgery Needed?

Open-heart surgery is sometimes done to perform a Coronary Artery Bypass Graft (CABG). It may be needed if a person has coronary heart disease, a condition in which the blood vessels that supply blood and oxygen to your heart become narrow and stiff.

This narrowing happens because fatty substances build up inside the artery walls, and this process is called atherosclerosis.

When the arteries are blocked and narrowed, blood can’t flow well to the heart, which can cause chest pain, heart attacks, and heart failure.

Doctors may also do open-heart surgery to:

• Repair heart valves that control blood flow through the heart.
• Fix damaged and abnormal parts of your heart.
• Replace a damaged heart with a healthy donated heart.

What are the Common Conditions Treated by Open-Heart Surgery?

Heart surgery is done to treat different heart problems, and the type of surgery you need depends on your specific heart problem, your age, your overall health, and other personal factors.

Below are the most common heart problems that may require surgery:

⦿ Aneurysm

An aortic aneurysm is a swelling in the aorta (the main artery that carries blood from your heart to your body). Normally, the aorta has strong, thick walls. But health problems and injuries can weaken these walls. When the walls are weak, the pressure of blood can make them bulge, which can be dangerous if not treated.

⦿ Arrhythmias

Arrhythmias are problems with how fast and slow your heart beats or if it beats in an irregular pattern. If medicines and other treatments don’t work, doctors may do surgery to put a small device inside your body to control the heartbeat. These devices include pacemakers and implantable cardioverter defibrillators (ICDs).

⦿ Atrial Fibrillation

Atrial fibrillation is a very common type of arrhythmia, which means your heart is beating irregularly and not working as smoothly as it should.

⦿ Coronary Heart Disease

Coronary heart disease happens when the blood vessels that supply blood to your heart get narrowed and blocked. If this is serious, you may need coronary artery bypass grafting (CABG), also known as heart bypass surgery, to improve blood flow to your heart.

⦿ Heart Failure

Heart failure means the heart is not pumping enough blood to your body. This can happen if the heart doesn’t fill up with enough blood and if it’s too weak to pump blood properly.

⦿ Heart Valve Disease

The heart has valves that make sure blood flows in the right direction, and if these valves don’t open and close properly, blood flow inside your heart is affected. In such cases, the valves may need to be repaired and replaced.

⦿ Heart Valve Repair Surgery

Surgeons can repair valves in different ways depending on the problem, for example:

• Fixing and reattaching loose flaps in the valve.
• Patching holes and tears.
• Using a balloon to widen the valve opening so blood can flow better.

Surgical Technique for Open-Heart Surgery

◾ Coronary Artery Bypass Grafting (CABG)

CABG is the most common type of heart surgery. In this procedure, the surgeon takes a healthy blood vessel from another part of your body and attaches it to the heart so blood can flow around a blocked artery. Sometimes, more than one blocked artery is bypassed during the same surgery is also called heart bypass surgery or coronary artery bypass surgery.

◾ Heart Valve Repair and Replacement

If a heart valve is damaged, the surgeon can either fix it or replace it. Replacement valves can be man-made and made from pig, cow, and human heart tissue. One repair method uses a thin tube inserted into a blood vessel, helping it to the heart. A small balloon at the tip is inflated and deflated to widen a narrow valve.

◾ Pacemaker and Implantable Cardioverter Defibrillator (ICD) Placement

For irregular heartbeats, medicines are usually tried first; if they don’t work, a pacemaker can be placed under the skin of your chest and stomach. It’s connected to the heart with wires and sends small electrical signals to keep the heartbeat normal. An ICD works like a pacemaker but can also send a quick electric shock to fix dangerous rhythms.

◾ Maze Surgery

This surgery treats an irregular heartbeat known as atrial fibrillation. The surgeon makes small cuts in the upper chambers. These cuts help the heart’s electrical signals along a proper path, stopping them from causing irregular beats.

◾ Ventricular Assist Device (VAD) and Total Artificial Heart (TAH)

A VAD is a machine that helps the heart pump blood when it’s too weak, and a TAH replaces the heart’s two lower chambers completely, taking over their pumping function.

Recovery Tips from Open-Heart Surgery

Important Things to Know About Your Recovery After Open-Heart Surgery:

‣ Your Eating Habits Might Change

• After surgery, you may not feel like eating much, lose your appetite, or feel too tired to eat. This is normal and usually temporary.

‣ Tips:

• Eat small meals several times a day instead of big meals.
• Choose healthy foods to help your body heal and get stronger.

‣ You Might Have Trouble Sleeping

It’s common to have trouble sleeping after heart surgery because of the anesthesia, discomfort, changes in your routine, and stress. Most people start sleeping normally again in 2-3 weeks.

‣ Tips for Better Sleep:

• Rest during the day, but avoid naps longer than 20 minutes.
• If you have pain, take your pain medicine about 30 minutes before bedtime.
• Use pillows to find a comfortable position and reduce muscle strain.

Key Differences Between Bypass and Open Heart Surgery

Open heart surgery and Bypass surgery are complex surgeries that are done to treat heart problems. However, there are a few distinctions between bypass and open-heart surgery:

Side Effects of Bypass and Open-Heart Surgery

• Possible side effects include:
• Bleeding
• Arrhythmia
• Blood Clots, which can cause a stroke
• Damage to your Heart, Kidneys, Liver, and Lungs
• Infections
• Swelling
• Memory Loss and Other Cognitive Problems
• Pneumonia
• Death
• The risk of death is generally highest for people who are very sick before their surgery. However, emergency surgeries generally have higher rates of complications than planned surgeries.

The Recovery Time After Bypass and Open Heart Surgery

The recovery time after open-heart surgery is 4 weeks and and 2-3 weeks after heart bypass surgery as well.

Hospital Stay Expectations of Bypass and Open Heart Surgery

The hospital stay after open heart surgery is 8 days; however hospital stay after bypass surgery is 7 days.

To Keep Your Heart Healthy After Bypass or Open-Heart Surgery, make These Important Lifestyle Changes:
