title: [Surgery of aortic valvular disease with congenital bicuspid or quadricuspid aortic valve].
abstract: Twelve patients (age 18 to 69 years old) with surgical treatment for congenital bicuspid aortic valve and one (age 26 years old) for quadricuspid aortic valve were reported. These 13 patients occupied 12.3% of the total number of patients with aortic valve replacement during the same period. Among the patients with bicuspid aortic valve, 10 patients were male (83%) and 2 were female (17%). Seven patients exhibited aortic stenosis and 5 showed predominant aortic regurgitation. The mean age of patients with aortic stenosis was higher than that of patients with aortic regurgitation. (63.3 years vs 32.0 years old). Infective endocarditis occurred in 2 patients (17%). Three patients had pure aortic regurgitation without evidence of endocarditis. One 26-year-old female patient who had a quadricuspid aortic valve presented with aortic regurgitation associated with PDA. All patients underwent aortic valve replacement with no early and late deaths.
