Two puppies recently underwent heart surgery at the Hixson-Lied Small Animal Hospital which has greatly enhanced their lives. Hazel, a Cockapoo, and Hope, a Schipperke/Pomeranian mix, came to the College of Veterinary Medicine facility from Critter Crusaders in Cedar Rapids, an organization that provides advanced medical care for homeless, sick and injured pets in Iowa. Hazel was diagnosed with a serious heart condition known as patent ductus arteriosus (PDA). PDA is a congenital heart defect that results in abnormal blood flow between the heart and lungs. “If untreated, this condition can lead to congestive heart failure and a significantly shortened lifespan,” said Dr. Kimberly Spartz, veterinary cardiology resident at Iowa State. “Unless there are other abnormalities, the prognosis is normal with surgery.”
