Heart transplant surgery
Find out what happens during the transplant operation
- Heart transplant surgery lasts around 4-6 hours
- You will be put to sleep under a general anaesthetic while the transplant takes place
- Donor hearts are transplanted in the same place in your chest as your own heart
- The operation can be performed a variety of ways, which will depend on your needs and the preference of the transplant surgeon
How is heart transplant surgery performed?
Donor hearts are transplanted in the same place in your chest as your own heart. This involves the removal of the diseased heart and replacement with the donor heart.
How it works
Where the heart is in the body
Your heart sits in the middle of your chest, with a slight tilt to the left. It is connected to the body through various arteries and veins, including:
- The aorta - the main and largest artery in the body
- Superior vena cava - a large vein that brings blood to the heart from your upper body
- Inferior vena cava - a large vein that brings blood to the heart from your lower body
- Pulmonary blood vessels - arteries and veins that connect to your lungs

Arteries and veins run throughout the heart. In general, arteries take oxygenated blood away from the heart, while veins bring deoxygenated blood back to the heart. However, pulmonary blood vessels are the exception. Pulmonary arteries move deoxygenated blood from the heart to the lungs, and pulmonary veins carry oxygenated blood back to the heart from the lungs.
Connecting a donor heart
A donor heart is transplanted in the same place as your own heart. Your transplant surgeon will carefully join the donor arteries and veins surrounding the heart with your arteries and veins.

Some things that might happen during your heart transplant surgery
Example of a surgical heart transplant technique
After you have been put to sleep under anaesthetic, the surgery will begin.
You will be attached to a heart-lung bypass machine, which takes over the function of the heart and lungs and delivers oxygen to the body.
The entire operation takes around 4-6 hours.
