6 Year Old Dog With Subaortic Stenosis - 1

This case was a preoperative (non-cardiac surgery) echocardiogram for a six year old smooth coated terrier. The vet wanted to check that his heart was strong enough for anaesthesia. His left ventricular systolic function looks good, but even at first glance it can be seen that this dog has mild concentric hypertrophy. Common causes of hypertrophy are: Uncontrolled hypertension Aortic stenosis Hypertrophic cardiomyopathy (rare in dogs, and may not be concentric) We always check the mitral valve in dogs, but in this dog, we were most interested in the aortic valve. The valve itself appeared to open well, but there is clearly some turbulence before the valve highlighted by the colour Doppler. There also appears to be a shelf-like narrowing just before the left ventricular outflow tract.
