What is the Heart bypass procedure?

Doctors typically have a range of options at their disposal to fix the blockage. If left untreated, coronary artery disease can lead to heart attack and even death.

When possible, doctors may try to resolve the issue of blocked arteries with medication and less-invasive procedures, such as a stent.

If these options do not work or are not suitable for an individual, surgeons might decide to perform heart bypass surgery.

Heart bypass surgery is one of the most effective weapons against blocked arteries and the problems they cause.

The medical name for heart bypass surgery is coronary artery bypass graft (CABG).

During Coronary Artery Bypass Surgery

You will have general anesthesia for the surgery.

The first step in the surgery is for the surgeon to prepare the arteries or remove the veins that will be used as bypass grafts.

Next, the surgeon makes an incision down the center of your chest, through your sternum (breast bone), so your heart and coronary arteries can be seen. Your heart will likely be stopped for a short time so the surgeon can perform the bypass procedure on a “still” heart. During this time, the heart-lung bypass machine takes over for the heart and lungs, so blood keeps moving throughout the rest of the body. This is called “on-pump” surgery. The pump is turned off after the grafts are in place. Your heart beat and blood flow return to normal.

The surgeon takes a section of healthy blood vessel, often from inside the chest wall or from the lower leg, and attaches the ends above and below the blocked artery so that blood flow is redirected around the narrowed part of the diseased artery.

Other surgical techniques your surgeon might use include:

Off-pump or beating-heart surgery. This procedure allows surgery to be done on the beating heart using special equipment to stabilize the area of the heart the surgeon is working on. This type of surgery is challenging because the heart is still moving. It’s not an option for everyone.

Minimally invasive surgery. A surgeon performs coronary bypass through small incisions in the chest, often with the use of robotics and video imaging that help the surgeon operate in a small area. Variations of minimally invasive surgery might be called port-access or keyhole surgery.
