结局指标
主要结局
Effective Orifice Area (EOA)
时间窗: 6 month evaluation
Effective Orifice Area of the prosthetic valve measured via echocardiography to determine physiological area of blood flow through the valve.
Aortic Mean Gradient
时间窗: 6 months
Mean gradient measured across the aortic prosthetic valve via echocardiography to determine mean pressure of blood flow across the valve.
