Cardiac catheterisation in valve disease allows the investigator to see the jet, with reflux. Pressure gradients across the valve can be measured, and the coronary anatomy can be defined - in fact this is the only way of doing this.
In aortic and mitral regurgitation the severity is deduced from reflux of dye injected upstream; in aortic and mitral stenosis - severity from pressure gradient across valve.
