When is the mitral valve in the heart closed?

3 doctors weighed in across 2 answers

Systole: During systole ( when the left ventricle contracts) the valve closes due to increased pressure in the left ventricular cavity and it therefore prevents blood from leaking backwards into the left atrium.

Mitral valve: During ventricular systole the rising pressure in the left ventricle causes the mitral valve to close.
