Figure Legend:
The computational setup: The LV and the mitral opening are discretized with triangular elements required for the immersed boundary method. The LV does not move above S0, and completely moves below S1. The motion is constrained between S0 and S1 for a smooth transition between fixed and fully moving sections.

Figure Legend:
The volume of the LV from the lumped parameter model and the he nondimensional flow rate (nondimensionalized by Q0=UD2=5.019×10−4 m3/s =30.1 L/min) for different flow rates during one cycle. The positive values denote the flow out of the LV during systole, and negative values denote the flow into the LV during diastole. The flow during diastole shows two peaks: an early peak (E-wave) and a later peak (A-wave).

Figure Legend:
The H-efficiency is plotted against the heart rate for 40, 72, and 120 bpm. Simulations at 72 bpm show that global geometric perturbation of the left ventricle (LV) can affect the hydrodynamic efficiency (while ejection fraction and VFT remains unchanged).

Figure Legend:
The 3D vortical structures are visualized at different time instants in the cycle (marked on Fig. 2) using the iso-surfaces of q-criteria for heart rates 40, 72, and 120 bpm and the LVs with perturbed geometries at 72 bpm
