Aortic Bicuspidy: Clinical Profile and Surgery
Downloads
Objective:
To study the anatomic-clinical profile of aortic bicuspidy and the outcome of surgery.
Patients and Methods:
During an 18-year period, 448 patients had aortic valve replacement. Of these, 24 (5.3%) had aortic bicuspidy (AB). The diagnosis of AB was made by echocardiography or during surgery. All patients underwent surgery under extracorporeal circulation.
Results:
The mean age was 45.2 ± 11.8 years, 14 patients (58.3%) had aortic stenosis and 10 cases (41.7%) had aortic insufficiency, 4 of whom had infective endocarditis. All patients had aortic valve replacement. The operative mortality rate was zero. The mean times of the cardiopulmonary bypass (CPB) and aortic clamping were 99.2 ± 35.4 min and 65.8 ± 24.9 min, respectively.
Conclusion:
Aortic bicuspidy progresses rapidly and becomes symptomatic in young adults. Despite excellent surgical results, early detection is desirable before complications occur.
