save the life of child suffering from congenital heart diseases

My younger brother ,named Tanvir ,is a patient of congenital heart disease(single ventricle). During my childhood I saw that my brother was lin and thin but bluish, but can walk, play. But became tired after mild exertion.So my father came to Dhaka with my brother. A famous cardiologist saw him and advice to consult with a cardiac surgeon. That time cardiac surgeon sayed that my brother will not survive .After heard that my papa took decision to take him to India. And he did this . In India two cardiac surgeon suggest for operation. But they said that it is a new procedure. So that my papa back to home.

There after we planned that when the treatment will be improved then we will do that.I was then at school. After completion of my higher secondary exam I took admission in medical college. Gradually I can understand what is the diagnosis .I have read different books which were available to me.I asked to my senior but nobody gave me good answer. Not only that I took my brother to many cardiologist. They never suggest for any treatment.Only they treat the problem which we faced.But mom always asked me that I am a doctor but I can't do anything.Two to three years ago internet was not so available, so we contact with a doctor came from India. He said that it is risky to operate. I became silent for few months.My mom always ask me to take news. After repeated request of my mother i contacted with a cardiac surgeon . He advised to take my brother to India. Three months ago I took him there operated there . My brother is now well, can continue his university. My mom is very happy now. I also.
