My Brother's wife went in and had a heart valve replaced for the second time. After surgery she has taken a terrible turn for the worse. She had to be put back on a ventilator because her oxygen level is only 85%, they are doing dialysis through a port because her kidneys aren't functioning correctly and her blood pressure is really low. They are doing all they can do but it doesn't look good. She's in very critical condition. Her name is Shirley and all prayers would be very much appreciated. Thanks!!
