The procedure for my sister went well, but she began having problems after it was over. Possibly a heart attack and very unstable blood pressure. She was put on a respirator for 24 hours. She did talk to me, but is exhausted. The ICU nurse told me she was in serious condition, but was improving slowly. We won't know if she had a heart attack for a while - about 8 hours for those test results. Please keep her in your prayers. I'll update as I learn more about her conditon. Thanks to all who read, respond and send good thoughts and prayers.
