An increase of aortic valvular disease
associated with congenital bicuspid aortic valve is observed
due to the relative decrease of rheumatic valvular diseases.
A total of 24 patients with aortic valvular disease associated
with congenital bicuspid aortic valve underwent surgical treatment
at our institution during the period from January, 1997 to December,
1999. These 24 patients constituted 46.2% (24/52) of all cases
of surgical operations for aortic valvular disease. The age of
the patients ranged from 17 to 83 years (mean 62 years). They
consisted of 16 men (66.7%) and 8 women. Two patients had infective
endocarditis. The classification of congenital bicuspid aortic
valve was right-left cusp type in 15 patients (raphe{: 11), anterior-posterior
cusp type in 9 patients (raphe{: 9). We performed aortic valve
replacement in 22 patients, aortic root replacement in 1 patient
and aortic root remodeling in 1 patient in combination with mitral
valve plasty in 3 patients, coronary artery bypass grafting in
3 patients and closure of the atrial septal defect (ASD) in 1
patient. We detected ASD in 1 patient, ventricular septal defect
in 1 patient and high-posterior take-off right coronary artery
in 1 patient. Patients with stenosis often have a small aortic
annulus and severe post-stenotic aortic dilation. Preoperative
and intraoperative evaluation is important in cases of aortic
valvular disease associated with congenital bicuspid aortic valve.
