Hi my name is Emmarie and my dog Rosalina needs heart surgery, she was diagnosed with a patent ductus arteriosus (PDA) which is a congenital (she was born with it) heart defect in which there is an irregular transmission of blood between two of the major arteries in the heart. In the normal fetus, the blood by-passes the lungs through the “ductus arteriosus” because the lungs are not active and do not oxygenate the blood. When most puppies or kittens are born, the ductus arteriosus closes. A “patent” ductus arteriosus (PDA) means that this vessel remains open and blood gets re-circulated through the heart, making the heart work overtime and eventually leading to heart failure. In some cases, the blood flow reverses secondary to pulmonary hypertension, causing a portion of blood that has not been oxygenated by the lungs to flow to the body. Without funding she may not live a full and quality life. If you cannot donate please share to help get my Rosie get her surgery to close the vessel. Thank you!
