Abstract
Our attention was focused on the section dealing with the natural history of aortic stenosis (AS), particularly on these lines: “In most patients with severe AS, impaired platelet function and decreased levels of von Willebrand factor can be demonstrated. The severity of the coagulation abnormality correlates with the severity of AS and resolves after valve replacement . . . . After the onset of symptoms, average survival is 2 to 3 years, 10% to 11% with a high risk of sudden death. Thus, the development of symptoms identifies a critical point in the natural history of AS. The management decisions are based largely on these data; most clinicians treat asymptomatic patients conservatively, whereas corrective surgery is generally recommended in patients with symptoms thought to be due to AS.
