SEVERE STENOSIS INVOLVING A CONGENITALLY BICUSPID AORTIC-VALVE IN THE 10TH DECADE OF LIFE

Acongenitally bicuspid aortic valve (BAV) is present in at least 1% of persons.1 The most common complication of a BAV is stenosis, and this congenital malformation represents the most common cause of isolated aortic stenosis in the patient group aged 16 to 65.2 In patients over the age of 65, aortic stenosis superimposed on a BAV occurs with a frequency of approximately 10%. We recently encountered a 92-year-old man with severe aortic stenosis due to a congenitally BAV. To our knowledge, this is the oldest reported patient with severe stenosis involving a congenitally BAV. © 1990.
