The effect is to freeze much of the left ventricle, the heart's main pumpingchamber, disrupting its ability to contract and effectively pump blood.

High blood pressure eventually leads to enlargement of the main pumpingchamber of the heart, which is measured by the "left ventricular mass index" or LVMI.
A sheath (30) closes the opening (18) and embraces an inner portion of the plunger (25), whereby pumpingchamber (33) is defined between the pump body (11) and the sheath (30).
