Hi.. My name is Hassan and im from Maldives My younger brother was born a heart patient and had a heart surgery when he was very young. He was alright for days but now his case is a bit worse. we consulted a Cardiologist here in Maldives and he said that it maybe possible that there maybe a blood leakage in one of his veins..And he did not prescribe any medicine and we are worried..
