I know of people with MDS and other blood diseases who've been transfused for two decades or more, all still going strong. The only thing is that they have to manage iron overload after so many years. Iron usually has to fester in the body at very high levels for many years before it begins to cause liver or heart problems; and even then, it doesn't always, as it depends on the person's body chemistry.
No reason to worry about the transfusion route. It's all good.
Peace, health and happiness to you!
