Location:
The left ventricular apex is located at the bottom of the left ventricle inferior to both the mitral and aortic valve. It is close to but separated from the right ventricular apex by the interventricular septal wall.

Importance in device delivery:
The apex of the left ventricle is a potential entry sight into the left ventricle for valve therapies. Left ventricular assist devices can utilize the apex as a place to sew in blood conduits to fill the device with blood.
