Between left atrium and left ventricle; includes posterior and anterior cusps
Ventricular diastole: open valve allows filling of left ventricle.
Ventricular systole: closed valve prevents reflux from left ventricle to left atrium.
Importance in cardiovascular diseases:
Mitral valve stenosis, mitral valve insufficiency
Importance in device delivery:
Ablation catheter entanglement during retrograde aortic approach for left ventricular
and left atrial ablation
