Heart bypass surgery creates a new route, called a bypass, for blood and oxygen to reach your heart.
Minimally invasive coronary (heart) artery bypass can be done without stopping the heart and putting a patient on a heart-lung machine.
A heart surgeon will make a 3- to 5-inch-long surgical cut in the left part of your chest between your ribs. This allows the surgeon to reach your heart. Muscles in the area will be pushed apart. A small part of the front of the rib, called the costal cartilage, will be removed. Then the surgeon will find and prepare an artery on your chest wall to attach to your coronary artery that is blocked.
Once the above steps are done, the surgeon will connect the prepared chest artery to the coronary artery that is blocked.
You will not need to be on a heart-lung machine for this surgery, but a device will be attached to your heart to stabilize it. You will receive medicine to slow the heart down.
Your doctor may recommend a minimally invasive coronary artery bypass if you have a blockage in one or two coronary arteries, usually in the front of the heart. When one or more of the coronary arteries become partly or totally blocked, your heart does not get enough blood. This is called ischemic heart disease or coronary artery disease. It can cause chest pain (angina).
Your doctor may have first tried to treat you with medicines. You may have also tried cardiac rehabilitation or other treatments, such as angioplasty with stenting.
Coronary artery disease varies a lot from person to person, so the way it is diagnosed and treated varies. Heart bypass surgery is just one treatment. It is not right for everyone.
Surgeries or procedures that may be done instead of minimally invasive heart bypass are:
Ask your doctor about the risks of surgery. In general, the complications of minimally invasive coronary artery bypass are lower than with open coronary artery bypass surgery.
Risks for any surgery include:
Possible risks of coronary artery bypass include:
Always tell your doctor or nurse what drugs you are taking, even drugs or herbs you bought without a prescription.
During the days before the surgery:
The day before your surgery:
On the day of the surgery:
Your doctor or nurse will tell you when to arrive at the hospital.
You may be able to leave the hospital 2 or 3 days after your surgery. You may also be able to return to normal activities after 2 or 3 weeks.
Recovery from surgery takes time, and you may not see the full benefits of your surgery for 3 to 6 months. In most people who have heart bypass surgery, the grafts remain open and work well for many years.
This surgery does not prevent a blockage from coming back. However, you can do many things to slow it down. Not smoking, eating a heart-healthy diet, getting regular exercise, and treating high blood pressure, high blood sugar (if you have diabetes), and high cholesterol will all help.
You may be more likely to have problems with your blood vessels if you have kidney disease or some other medical problems.
