Cardiac Allograft Vasculopathy (CAV)

What is CAV?

CAV is a form of chronic rejection that narrows the blood vessels of your transplanted heart. We
check for CAV by doing a yearly cardiac cath or dobutamine echocardiogram. CAV affects the
entire length of the vessel, not just one spot. CAV is not caused by plaque, but rather the vessel
wall grows in thickness, leaving less room for blood to pass through. It may come on quickly.
Generally, collateral or smaller natural bypass vessels do not form. The use of stents or bypass
surgery is very difficult and often not helpful. For this reason frequent monitoring and
preventive care is the best management for CAV.

Who is at risk for CAV?

All heart transplant patients are at risk for CAV. CAV affects men and women, adults and
children of all races who have had heart transplants. CAV can occur early after transplant, but
the frequency increases over time after transplant.

What can we do to prevent CAV?

Manage your risk factors that you can change:

▪ Lower your cholesterol through diet, exercise and medications.
▪ Control your diabetes.
▪ Maintain a healthy blood pressure.
▪ Maintain a healthy weight.
▪ Do not smoke and avoid exposure to second hand smoke.

Take your immunosuppressant medicines as prescribed.

▪ Because CAV is a form of chronic rejection, it is vital to take all of your
immunosuppressant medicines as prescribed.
▪ Take “statin” drugs even if you do not have high cholesterol. They work in such a way
that they may decrease the risk of CAV.
▪ Sirolimus; a drug that prevents rejection and also works to prevent CAV, may be added
to your treatment if you develop CAV. It has been shown to decrease the worsening of
CAV.
