The disclosure relates to a device for supporting functions of a heart valve and methods for making and using the same. The device includes a flow optimizer configured to be located in the valve and having a cross sectional area that reduces a regurgitation orifice of the valve during systole. The device includes an anchoring mechanism coupled to the flow optimizer and configured to fix a position of the flow optimizer relative to the valve. The flow optimizer allows hemodynamic flow during diastole, minimizing risk of inducing atrioventricular pressure gradient and thrombogenesis, and seals or minimizes the regurgitation orifice during systole and reinstates efficacy of the valve. The anchoring system requires no traumatic interaction with the valve, atrium and ventricle. Implantation of the device can be achieved without invasive surgery. The device permits intra-procedural optimization of the positioning of the flow optimizer.
