Coronary bypass surgery without a pump

No-pump coronary bypass surgery aims to reduce the risk of complications from coronary artery bypass surgery such as stroke, kidney failure and the need for blood transfusions.

An overview of coronary bypass surgery without a pump

If you have coronary artery disease (CAD), in which one or more of the main blood vessels that supply your heart are blocked, you may have a procedure Coronary artery bypass surgery.

The desire to improve outcomes after surgery and advances in technology has led surgeons to perform coronary artery bypass surgery without cardiopulmonary bypass, which is called non-pump coronary artery bypass surgery (also called “beating heart” surgery).

Traditionally, it is made Coronary artery bypass surgery With the help of a cardiopulmonary pump.

The heart-lung machine allows the heart to stop, so the surgeon can operate on a surface free of blood.

The heart-lung machine keeps life alive despite the absence of a heartbeat, as it removes carbon dioxide from the blood and replaces it with oxygen before it is pumped throughout the body.

That is, it does the work of the normal human heart.
The artificial heart-lung machine has saved countless lives.

No-pump coronary artery bypass surgery is different from Conventional coronary artery bypass surgeryThis is due to the lack of an artificial heart-lung machine.
Instead of stopping the heart, technological advances and new types of operating equipment have allowed the surgeon to fix parts of the heart during surgery.
With a specific area of the heart immobilized, the surgeon can move forward and bypass the blocked artery in a highly controlled surgical environment.
Meanwhile, the rest of the heart continues to pump and circulate blood to the body.

Coronary artery bypass surgery without a pump can be performed in some patients with coronary artery disease.
With current technology, all heart arteries can be bypassed without a pump.
This solution may be ideal for some patients at increased risk of complications from cardiopulmonary bypass, such as those with severe aortic calcification, cirrhosis, or impaired lung or kidney function.

But of course, not all patients are suitable for this method of operation.
The patient who can undergo the operation without a pump is chosen after his heart and arteries are closely evaluated.

Coronary artery bypass surgery without a pump is now possible, but is it better?

No-pump bypass surgery aims to reduce the complications of coronary artery bypass surgery, such as stroke, kidney failure and the need for blood transfusions.

Also, the possibility that working without a pump may reduce the risk of so-called cognitive changes that have been observed in many patients who underwent coronary bypass surgery.

Surgeons at the Cleveland Clinic completed a study comparing the outcomes of coronary artery bypass surgery with and without a pump.
The researchers compared 406 patients without a pump and 406 patients with a pump.

They found that the results of the surgeries without a pump were excellent.

The risks of stroke, heart attack during surgery, and death were similar and low in patients undergoing no-pump CABG.

One concern that has emerged in recent multicenter studies is that patients who did not use the pump had less complete vascular connections.
This means that fewer patients fully restored blood flow compared to patients who used the pump.

In fact, the results showed American Heart Association In bypass surgery, fewer surgeons are now performing a CABG without a pump.

However, he notes, surgeons have been able to reconstruct blood vessels in nearly all patients.

The results of coronary bypass operations without a pump are very excellent.

Both procedures have a very low risk of death, stroke and myocardial infarction (heart attack).

The advantage of non-pump surgery is that coronary artery bypass grafting can be significantly reduced in carefully selected patients.

We tailor the process to the patient's specific needs and circumstances. This helps provide better outcomes for patients.

Are There Patients Who May Benefit From No-Pump Coronary Bypass Surgery?

Patients at high risk of complications from cardiopulmonary bypass, such as people with vascular disease, previous strokes or liver disease, may benefit from non-pump revascularization.

Surgeons are constantly looking for new ways to improve outcomes in both types of surgery.
For example, in pump surgery, improvements are being made to the heart-lung machine, a filtration device has been designed that can pick up small clots before any damage occurs and is now being tested.

In non-pump coronary bypass surgery, different methods are researched and developed to stabilize small parts of the heart during surgery so that the surgeon can operate on them while the heart continues to pump blood.
