Thank you so much for all of the good thoughts, kind words, and prayers. To answer your question, njean, mom is having the surgery at NY Presbyterian Hospital in New York City. Her surgeon is Dr. Karl Krieger. We are not totally sure yet what valves she will be getting- we are almost definite that they are going to be mechanical, but she is not sure whether to go with the St. Judes or the On-X. My mom has decided that she will go with whichever one Dr. Krieger has more experience with (I'm assuming that will be St. Judes). I think she should get the 'variety pack' and do one of each. Just kidding. Jeez I can't wait till this surgery is over. I am ready to be taking some slow walks and giving some back and shoulder rubs to my post-op, ticking mom.
