This adorable 3 month old is Archie! 😍
Following adoption, he was seen at VCA North Portland Veterinary Hospital for a wellness exam. His physical exam revealed a grade 2/6 heart murmur that had progressed to a grade 3/6 at a subsequent visit 2 weeks later.
Archie then presented to CVCA (🙋♀️) for an initial evaluation to assess the heart murmur further. Dr. Gregg Rapoport, DVM, DACVIM found that Archie’s heart murmur is related to the speed of blood flow in a specific area of his heart, namely the area where blood leaves the left ventricle and passes through the aortic valve to enter the aorta. In this location, blood flow velocity is high enough to be heard as a murmur, particularly when Archie is more excited or anxious. In the absence of any structural abnormalities in this area of the heart, such as backward flow across the aortic valve (aortic regurgitation), blood flow turbulence, or a visible obstruction to blood flow (subaortic ridge), this would be considered normal variation in an adult dog.
In some dogs, this same finding can be the result of a congenital heart disease called “aortic stenosis.” This is an abnormal narrowing (stenosis) in this region of the heart. The stenosis is typically just below the level of the aortic valve, technically referred to as “subaortic” stenosis. In more severe cases, this obstructs forward blood flow, requiring the left ventricle to become stronger and thicker to send blood into the aorta. While this defect is congenital (present since birth), the narrowing can become more severe during the first one to two years of life.
We are hopeful that this will not be a significant problem for Archie and we will be sure to keep a close eye on him! We love you Archie!! ❤❤
