Simulation of LVAD

LVAD : Left ventricular assist device

LAVD therapy : Energy Unloading

- Pressure & Volume unloading

- Energy unloading

Simulation of regurgitation

Simulation of heart valves regurgitation

Transmural strain and tension

Transmural distribution of tissue strain at end-diastole and tension at end-systole. Systolic tension in the LV septum and free wall was significantly lower for MR than for AR. However, end-diastolic strain was increased under AR and MR conditions
