25 Questions and Answers
Coronary bypass surgery restores blood flow by creating a new route around the blocked coronary artery using a vessel taken from elsewhere in the body. The blocked artery is not opened — a new path is built alongside it.
Coronary artery blockages are the most common indication. Valve disease, congenital heart defects, cardiac tumours, aortic aneurysms, and infections such as endocarditis may also require open-heart surgery. The treatment plan is tailored to the patient's age, vascular anatomy, and cardiac function.
Usually yes. In the conventional method (On-Pump), the heart is stopped and a heart-lung machine takes over. With the "Beating Heart Bypass" (Off-Pump) technique, surgery can be performed without stopping the heart.
Every major surgery carries risk. With today's technology, the mortality rate for bypass surgery has fallen to around 1–2%. This rate may vary depending on the patient's age and co-existing conditions such as diabetes or kidney failure.
If no complications arise, the patient is usually monitored in the ICU for 1–2 days before being transferred to a regular ward.
If recovery proceeds normally, the patient is typically discharged between days 5 and 7 after surgery.
Bypass surgery aims to extend life expectancy. With a successful operation and a healthy lifestyle (no smoking, appropriate diet), patients can live a normal lifespan. Grafts using the internal mammary artery (LIMA) have a patency rate exceeding 15–20 years.
Yes. Surgery does not eliminate atherosclerosis. If the patient continues to smoke, does not take medications, or fails to control cholesterol, the new grafts can also become blocked over time.
This decision is made by the Heart Team. For simple narrowings in one or two arteries, a stent is preferred. For multi-vessel disease, left main artery blockage, or diabetes, bypass surgery provides a more durable long-term solution.
The sternum (breastbone) takes an average of 6 weeks to fully fuse. Movements that strain the bone should be avoided during this period.
Sleeping on your back is recommended for the first 4–6 weeks to allow the sternum to heal properly. Lying on your side may compromise bone stability and cause pain.
Yes. After the saphenous vein is harvested, numbness, tingling, or mild swelling may occur in that area. Wearing compression stockings and keeping the leg elevated helps reduce these complaints.
Usually 4–6 weeks after discharge, once the patient feels physically ready and sternal pain has subsided.
To avoid pressure on the sternum and to allow reflexes to fully return, driving is recommended from weeks 6–8 after surgery.
Once the stitches are removed or the wound is fully dry (usually 2–3 days after discharge), a lukewarm standing shower is allowed. Scrubbing the wound should be avoided.
There is no strict age limit. Patients over 80 can undergo successful bypass surgery if their overall condition permits. The decision is based on biological age and organ function.
Yes — and in diabetic patients with multi-vessel disease, bypass surgery produces significantly superior outcomes compared to stenting and extends survival.
A heart-friendly Mediterranean Diet should be adopted: avoid solid fats, excess salt, and red meat; focus on olive oil, fish, vegetables, and fruit.
Smoking is the greatest enemy after bypass surgery. Continuing to smoke greatly increases the risk that the new grafts will become blocked rapidly.
Patients whose saphenous vein was harvested are recommended to wear compression stockings for approximately 4–6 weeks to prevent leg swelling (oedema).
Yes. Temporary emotional sensitivity, irritability, or low mood is common after major cardiac surgery. This usually resolves on its own as recovery progresses.
Desk workers can generally return after 4–6 weeks. Those in physically demanding jobs may need to wait 2–3 months.
The most frequently used and most durable graft is the internal mammary artery (LIMA) from inside the chest. The saphenous vein from the leg and the radial artery from the arm are also commonly used.
Women's smaller vessel diameter can make the surgery technically more challenging, but in experienced centres, success rates for men and women are comparable.
After the first 6 weeks, regular walking is the best exercise. Heavy lifting and sports that stress the sternum (tennis, weightlifting, etc.) should be avoided for the first 3 months.
