Composite Graft Surgery



If we look at the organs that are important for our heart, then aorta comes somewhere on the top. Any complications of aorta can prove to be dangerous for our health. Quick and timely check up is a must. If there is something in our aorta, then the best way to deal with that problem is to go for Composite Graft Surgery.

A composite graft surgery is needed when there is a problem with our aorta. The most common problem that arises is the aneurysmal dilation of the aortic root that is associated with the aortic valve dysfunction. The long term results in the patients who undergo this surgery have been excellent and the chances of reoperation are also minimum.

Why it’s done

There are different reasons to consider composite graft surgery –

  • You have severe chest pain which is caused by the narrowing of the artery. These arteries supply the heart muscle with blood. Even during light exercise, your muscles will be short of blood.
  • It is suggested in case of one or more diseased coronary artery. In this condition, the heart’s main pumping chamber – the heart left ventricle – isn’t functioning well.
  • Your left main coronary artery is severely narrowed or blocked. This type of artery supplies most of the blood to the left ventricle.
  • In case of blocked artery, where other methods and procedures are not helpful.


  • To make insertion of composite graft easier, a technique was developed in which a 10-mm interposition tube graft was looped between the two coronary ostia and then the loop was reattached to the ascending aortic composite valve graft by side-to-side anastomoses.
  • With the help of this approach, access to the anastomoses has become easier for the purpose of obtaining hemostasis at the suture lines.
  • In some of the cases, where the tube graft is placed to the left of the ascending aortic graft, limb to the left coronary artery tends to kink.
  • And if the placement is to the right of the ascending aortic graft, then the side-to-side anastomosis has to be placed high on the aortic graft and high on the aortic graft.
