Thanks for your question on Healthcare Magic.
I can understand your concern.
She is having very poor functioning of heart, only 15-20%.
This is the cause for her poor
kidney functions.
Actually poor heart function causes poor circulation of blood in the body.
So all organs of the blood receive less blood.
So functions of the vital organs like kidney, Brain etc will be hampered.
So Honestly speaking, prognosis in her case is not good.
Life expectancy in her case is less than 6 months.
Hope I have solved your query. I will be happy to help you further.
Wishing good health to your mother. Thanks.
