Natural History
Bicuspid aortic valve, during childhood functions without any significant pressure gradient. However, the thickening and calcification of the valves may be detectable pathologically and on echocardiography by second decade[1]. This progresses to aortic stenosis in approximately 75% of cases requiring surgery.[2][3]
Bicuspid aortic stenosis progressively leads to heart failure, arrythmias, angina and other symptoms which generally manifests between 40 to 60 years of age which is relatively younger to manifestation of aortic stenosis otherwise.[2] However, children who develop early pathologic changes in bicuspid aortic valve are more likely to develop aortic insufficiency than stenosis.
Complications
Bicuspid aortic valve has a varied clinical manifestation as listed below[3]:
- Aortic stenosis in majority of patients.[2]
- Aortic insufficiency
- Endocarditis
- Aortic aneurysm
- Aortic dissection
