Aortic Valve: Difference between revisions

With 2D echocardiography, the valve can be assessed in the PLAX, where one sees the RCC and the NCC. In a normal aortic tricuspid valve, the closure line is between the RCC and NCC and usually in the center of the aortic valve ring. However, the aortic valve can be even better assessed in the PSAXao, where the three cusps in systole almost form a circle and in diastole in an inverted Mercedes-Benz logo. Assessing the number of cusps is done in systole, because the valve is open and because in the closed position raphes can be misinterpreted. With 3D echocardiography you can now also get wonderful images of the aortic valve.
