Stenosis – Have We Come Full Circle?

In 1994, Richard Kienle and colleagues published a paper examining the natural history of dogs with subaortic stenosis (SAS).1 Using a fairly well accepted classification scheme (mild SAS = pressure gradient less than 50 mmHg, moderate SAS = pressure gradient between 50 mmHg and 80 mmHg, and severe SAS = pressure gradient greater than 80 mmHg), they found that dogs with mild SAS essentially lived normal lives, although they had an increased risk of aortic valvular endocarditis. Those with moderate SAS had unpredictable life expectancy.
