### input:
My mother was 74yrs old. Had kidney transplant 03-05-15 after 9years of dialysis 3x a week. During the transplant she had mild heart attack and received a stent that later deflated. She needed an open heart surgery but due to transplant open heart was postponed and she was sent to rehab to build up strength. I found my mother laying on her rt side on the floor in the bathroom the morning of June 08, 2015. While on the phone with 911 I was asked to turn her over to her back. When I did she had white foam coming out of her mouth and nose. She could not be revived as the rep from the ambulance said we are sorry for your loss and it was difficult because their was not a life line to work with. Based on the position I found her in she must had just gotten off the commode. Her cane was in the bathroom so I know she had it with her when she went in there. She was on oxygen at night and was ok for sleeping that night before we went to bed. The hospital had sent mom home 05-26-15 and for some reason postponed the less invasive procedure TAVR out for 3months. Can you help me understand from a medical standpoint what may have happened to my mother in the bathroom.

Hello .sorry for Your loss... this is case of sudden death .if u noticed her with in 30-min her going in bathroom .......as she is already heart patient .and kidney pt ...may be old age also ....this most probably died to ventricular tachycardia episode OR some other irregular and fast heart rhythm ...which leads to sudden stoppage of heart ...whicChatDoctormon if heart is damaged ....usually if patient luckily survived then we can PUT ICD IMPLANT .if patient is having heart arrhythmia problem ..... I think not to think much...regarding this because it will be painful for u...nothing more u can do...every thing is not preventable
