Prayers Needed.

My brothers ex-wife and mother of my niece has been told she will need open heart surgery very soon. Tomorrow she will have more test done and they will set the date for the surgery. Apparently one of the valves leading to her heart is not right. Most people have a valve that is 3cm and at 5cm it is considered to be very bad. Hers is 8cm. She is only 33. I can't imagine her not being in my nieces life. She is in danger of having a heart attack at any moment. Please pray that she stays healthy until she has the surgery and that the surgery will go smoothly.
