   • The effects of having a faulty heart value can include heart failure, stroke, blood clots or death due to sudden cardiac arrest.

9. What is a long term treatment for heart or lung failure?
   • In the case of heart failure a donor heart, or heart and lungs can be transplanted.
10. When is it appropriate to use an artificial heart?
    • Artificial hearts are occasionally used to keep patients alive whilst waiting for a heart transplant, or to allow the heart to rest as an aid to recovery.
