Recently, the daughter began to get tired quickly, it is difficult for her to walk - she suffocates, shortness of breath. We were examined, and it turned out that Katya had a heart defect - a defect of the atrial septum. It is necessary to operate, doctors say. In early childhood, her daughter had already undergone five surgeries - she had a tumor removed from the retina. Now Kate has another operation on her heart. We went for a consultation to Kyiv, to the Amosov Institute, where we confirmed the diagnosis. Cardiac surgeons believe that surgery can be performed in a gentle, endovascular way, using a special "patch" - an occluder. The operation itself will be performed according to the quota, but you have to pay for an expensive occluder. And we do not collect the necessary amount, we are raising two children, my husband and I have enough salaries only for the most necessary things. Help us, please. Elena Semenova, Odessa.
