What Happens During Heart Bypass Surgery?


Heart bypass surgery is known to be the most common kind of heart surgery that is performed on adults. Doctors usually recommend this surgery when one or more blood vessels transporting blood to the heart muscles become blocked partially.

A number of heart hospitals in Delhi consider heart bypass surgery to be a complicated procedure which involved a good amount of preparation and recovery time. There are also the instances where a person must undergo emergency bypass surgery, however, most of the times, the operation is planned.

In this world of medical advancement, bypass surgery has become a safe and effective procedure which reduces the risk of heart attack and death. The procedure also helps to ease symptoms of coronary artery disease including chest pain.

Before the procedure:

A patient will be admitted to the hospital on the day of the surgery if the surgery is a planned one, not emergency heart surgery.

During the procedure:

According to the best heart hospital in Delhi, bypass surgery generally takes a time of 3-6 hours and requires general anesthesia to be administered to the patient. Most numbers of coronary bypass surgeries are done by the way of making a long incision in the chest whilst a heart-lung machine keeps the oxygen and blood flowing through the body. This is known as on-pump bypass surgery. The surgeon of a heart hospital in Delhi cuts the center of the chest and the breastbone, thereby spreading open the rib cage in order to expose the heart.

Once opened, the heart is temporarily stopped with medication and the machine takes over to circulate blood to the body. A healthy section of the blood vessel is taken from inside the chest wall or lower leg and the ends of it are attached above or below the blocked artery such that the flow of blood is redirected around this narrowed part of the diseased artery.

An off-pump or beating heart surgery is also performed which allows the surgery to be done on the beating heart. This is done by the way of using special equipment to stabilize the area of the heart on which the surgeon is working. This kind of bypass surgery is a little challenging to perform as the heart is still working.

Another bypass surgery known as minimally invasive surgery is also performed under which a surgeon performs a bypass by the way of making small incisions in the chest by the way of making the use of robotics and video imaging. Variations of this minimally invasive surgery are called port-access or keyhole surgery.

After the completion of the graft, the surgeon then restores the heartbeat, disconnects the patient from the heart-lung machine as well as makes the use of wire in order to close the chest bone. This wire then remains in the body till the time the bone heals itself. After the procedure, a patient is expected to spend a day or two in the ICU. A breathing tube shall remain in his throat until he is awake and is able to breathe on his own.
