Mitral Valve Prolapse. Need Help!!

Good day everyone, 
I'm MJ 24 years old from the Philippines. I have a sister suffering from  a heart disease called MITRAL VALVE PROLAPSE disease, she got this disease since she was 11 or 12 years old and she was 20 years old now. Her heart had an irregular beat, it beats very fast and when I saw her x-ray I saw that her heart seems like enlarging. The heart doctor here in the Philippines said that the only thing that can help her is an operation. And also she got a weak lungs, she always had a cough. My family here in the Phillipines only live a simple life. My father is working only in a factory as a factory employee, his salary is just enough for our basic needs like food. I'm just starting to work to be able to help my family and for the medicine of my sister. We can't afford the operation of my sister that's why she still have this disease 9 years until now. I really want to help my sister become healthy again, she is very thin now. I'm very sad that I can't help her with her operation, she can't go to school because one time she went to school and came home, she starting to cough and became ill again, so she stopped schooling. I was so sad seeing here with that condition. 
I will take this opportunity to find help. 
Is there anyone here or is there any heart doctor here who can help my sister for her surgery?. Please help us, especially my sister. I will really really appreciate it and I'm very very glad to say thank you!! God bless to all of you!! I'm so happy that I found this site where I'm able to share the story of my sister. Thank you so much! If anyone wants to help us, please send me an email, my email address was sakucent_10@yahoo.com.. Thank you so much!
