Heart-Lung Machine: The “Life Support” of Surgery
So, how does this machine work, and why is it so important?

Our heart is a muscle mass that pumps blood to the body. During heart surgeries, it is not possible to open the heart and perform the operation without stopping the blood flow to it. For this reason, the heart-lung machine is indispensable for the vast majority of heart surgeries.
- Function: The heart-lung machine temporarily takes over the patient’s body circulation. It receives deoxygenated blood from the body, oxygenates it, and pumps it back into the body. Thus, all organs receive sufficient oxygen throughout the surgery.
- Importance: Stopping the heart allows the surgeon to perform highly precise and detailed interventions in a stable and “bloodless” field, rather than working on a moving organ. After the surgeon completes the procedure, the heart is restarted, and the patient is weaned off the heart-lung machine to natural circulation. This transition process is carefully controlled by the anesthesiologist and surgical team, and once the heart’s rhythmic function is restored, the patient is transferred to the intensive care unit.
Sternotomy: The Wide Path to the Heart
The most common incision method used to access the heart in open-heart surgeries is called sternotomy.
- Application: Sternotomy is performed by cutting the breastbone (sternum), also known as the sternum, along its entire length through the midline of the chest. After the breastbone is opened, the rib cage is gently separated to both sides with a special metal equipment (retractor).
- Advantage: This method allows the surgeon full and wide access to all areas of the heart, major vessels, and surrounding tissues. Especially when working on complex structures or encountering an unexpected situation, this wide field of view offers the surgeon an indispensable advantage. Heart valves, coronary arteries, major arteries, and the heart wall can be clearly seen, which allows the surgery to be performed both safely and effectively.
Advantages of Open-Heart Surgery: Why Is It Still Preferred?
Although transcatheter procedures have advanced, open-heart surgery is still considered the “gold standard” in many situations. The main reasons for this are:
- Comprehensive Intervention Capability: The surgeon can directly access every region of the heart and intervene in all types of complex heart diseases. Advanced procedures such as repairing holes in the heart (like ASD, VSD), replacing or repairing heart valves, removing tumors, and major vascular changes (aortic aneurysm repair) can be successfully performed with open-heart surgery.
- Proven Success and Experience: It has been applied worldwide for many years and is the method with the most experience in surgical literature. This extensive knowledge base allows for the prediction of complications and ensures a high success rate.
- Reliability: Thanks to the controlled environment provided by the heart-lung machine, surgeons can operate with the precision that comes from working in a stopped, motionless, and bloodless heart. It provides critical reliability, especially in situations requiring very fine sutures or the repair of small vessels.
Summary: Frequently Asked Questions (FAQ)
How long does open-heart surgery take?
It usually takes between 3 and 6 hours. The duration may be longer in more complex cases.
Is open-heart surgery painful?
Since it is performed under general anesthesia, no pain is felt during the procedure. Pain is controlled with medication in the postoperative period.
What are the risks of surgery?
Bleeding, infection, stroke, heart attack, kidney failure, lung problems, and rarely death can occur. In modern medicine, efforts are made to minimize these risks.
How long does it take to recover?
It usually takes 3-4 weeks. This period is critically important for the breastbone to heal.
What is the difference from minimally invasive methods?
In minimally invasive surgery, smaller incisions are made. However, since a heart-lung machine is used, MICS is also a type of open-heart surgery.
When can sexual activity be resumed after surgery?
Generally, it is possible after 4-6 weeks, as the breastbone begins to heal.

Conclusion
Open-heart surgery is one of the most important achievements of modern medicine and has saved millions of lives. Although it has a complex structure and a long recovery period, it continues to be an indispensable solution for many heart patients due to the definitive treatment and high success rates it offers.
