Happy Wednesday from ZOE! 😍
Zoe's recheck echocardiogram revealed that she has a very mild form of a congenital heart condition called subaortic stenosis. This refers to a narrowing (stenosis) in the region of the heart just below the aortic valve, where blood leaves the left ventricle (the main pumping chamber of the heart) to enter the aorta. The narrowing results in an obstruction to forward blood flow that, in severe cases, requires the left ventricle to become stronger and thicker in order to send blood into the aorta. Abnormally fast and turbulent blood flow downstream of the obstruction can disrupt the normal function of the nearby aortic valve, resulting in backward flow across this valve (called aortic regurgitation). Fortunately for Zoe, the degree of her subaortic stenosis is extremely mild. In addition, because she has reached full adulthood, the severity of her condition is not expected to increase in the future. YAY! 🥳
Regarding the mild thickening of her mitral valve and very small amount of backward flow across it, this has proven to be remarkably stable over time. Although some degree of heart chamber enlargement was noted during one evaluation in September of 2018 (leading to the use of pimobendan), this now appears to have been an anomalous time point. Following previous normalization of heart chamber size and then discontinuation of the pimobendan last September, Zoe continues to be free of any apparent heart chamber enlargement!!! Best news EVER!! 👏🏽
As much as we will miss Zoe's visits, we do not have a plan for further cardiology appointments for Zoe. We love you Zoe! ♥️
