Tin is a 37-year-old woman from Burma who lives with her family and works as a schoolteacher. Two years ago, Tin started to experience difficulty breathing when walking up the stairs to get to her classroom. She could feel her heart beating fast and often experienced shortness of breath when performing regular daily activities. Tin later visited a local clinic, where doctors explained that she has a large hole in her heart. Over time, the medications that she received stopped working. Tin visited several other clinics and spent a lot of money to treat her condition, however her symptoms failed to improve. Finally, Tin was referred to our medical partner, Burma Children Medical Fund (BCMF), for further treatment. BCMF is requesting $1,500 to cover the cost of an atrial septal defect closure that will close the hole in Tin's heart. The treatment is scheduled to take place on July 15, and, once completed, will hopefully allow Tin to live much more comfortably. "Currently I am still suffering from the same symptoms, but I cannot take too much time off work, otherwise my salary will be cut," says Tin. "Once I recover, I hope to return to teaching private lessons to my students."
