Aortic valve disease is common. In Western populations, about 25% of people aged over 65 have aortic sclerosis, and 3% over 75 have severe stenosis.¹ In 2003, 6028 aortic valve operations were done in Britain and Ireland compared with 25 277 for isolated coronary disease.² Despite this the diagnosis may often be missed. Probably half are still diagnosed at postmortem examination, and 5% of operations are performed at end stage.³ Unrecognised aortic stenosis is an important cause of anaesthetic and obstetric mortality.

The overwhelming cause of aortic valve disease in Europe is calcific degenerative disease, and about 2% of the population have congenitally bicuspid aortic valves. Rheumatic disease is now rare. Stenosis is differentiated from sclerosis, when a restriction of cusp movement and a raised transaortic peak velocity are seen on echocardiography. Around 16% of patients with sclerosis progress to stenosis in seven years.⁴ The early lesions of calcific . . . [Full text of this article]
