Final answer:

The bicuspid (mitral) valve opens when left atrial pressure surpasses left ventricular pressure.


Explanation:

When left atrial pressure exceeds left ventricular pressure, the bicuspid (mitral) valve opens. This event allows blood flow from the atria into the ventricles, preparing for the next phase of the cardiac cycle.
