g) Preoperative cardiac________ is routinely performed to provide definitive assessment of aortic valve area and the pressure gradient, as well as to assess the coronary arteries for significant stenosis.

- The term for a narrowing of the bicuspid valve is: A: atrial prolapse B: pulmonic stenosis C: mitral stenosis D: mitral prolapse
- The aortic valve keeps the blood moving from veins to the heart.
- In order to ensure that the pressure difference between the front and rear of the throttle valve remains unchanged when the load changes, the flow through the throttle valve is basically unchanged. The throttle valve is often connected with ( ) to form a speed control valve, or the throttle valve and ( ) are connected in parallel to form a bypass speed control valve. A: Pressure reducing valve B: constant pressure reducing valve C: overflow valve D: differential pressure relief valve
