Isovolumetric relaxation ends when which event occurs?

Explanation:
Isovolumetric relaxation is the early diastolic interval when the ventricle relaxes but all valves are closed, so the volume doesn’t change and LV pressure falls. It ends when the mitral valve opens, allowing filling to begin. This follows after the aortic valve has already closed, leaving both the aortic and mitral valves closed during relaxation. The mitral valve opening marks the transition out of isovolumetric relaxation into filling.
