The diagnosis and treatment of the disease were reported in 11 cases. Methods Eleven patients （nine men and two women, mean age 33.4 years） with quadricuspid aortic valve were retrospectively evaluated. Medical records, echocardiograms and surgical treatment were reviewed. Results In accordance with the Hurwitz and Roberts classification, the patients were classified as type A （n=-2）, type B （n=7）, type F （n=1） and type G （n=1）. Three patients were associated with other heart diseases, including infective endocarditis and mitral prolaps, left superior vena cava, aortic aneurysm. All had aortic regurgitation （AR） except two with aortic stenosis （AS）, detected by color-flow Doppler echocardiography. The congenital quadricuspid aortic valve deformity in seven patients was diagnosed by echocardiography. All patients underwent successful aortic valve replacement. Conclusion Quadricuspid aortic valve is a rare cause of aortic insufficiency, while echocardiography plays an important role in diaanosina the disease. Aortic valve reelacement is the major therapy for the disease.展开更多
