Does anyone know anything about this? My 5 year old bichion was just diagnosed with this. We tooke her in for an xray because we figured she developed another stone.......which she has! They used the large xray/film to take the xray and they discovered that her heart is enlarged and that she has fluid build up. So they have put her on meds and said that it was caught early enough where she will live a normal life. She will have to be on meds for the rest of her life! We are devasted and we are hoping she will still live to a ripe old age. She showed no symptoms. That is why Im finding this odd! Anyone know anything about this please let us know! We just want her to be happy and comfortable as well as live a long life!
