Hello Noufissa.....Your daughter-in-law Suzanne tells me you are in the hospital waiting to feel better so you can have a valve replacement. Suzanne's mother, Nancy is a member of our group. We are over 500 members who chat to one another..We have all had open-heart surgery and are here to tell our stories...Do not be afraid. You will be fine...Soon it will be over and you will feel so much better. I know you do not speak English...Others will come along and wish you good luck and Suzanne will print the messages and bring them to hospital and read to you. You will be in our prayers. And Suzanne's Mother Nancy will let us know how you are feeling. Bonnie
