A method for changing minimally invasive or catheter-based the blood backwards flow rate in a replacement heart valve prosthesis wherein backwards flow means are manipulated to increase or to decrease the backwards flow rate.
A method comprising steps of:
- i) implanting a heart valve prosthesis, wherein the heart valve prosthesis is configured to provide an initial blood backward flow in a reverse direction of about 5 to about 40 percent of a forward valve flow when leaflets of the heart valve prosthesis are closed;
- ii) reducing the amount of blood backward flow in the reverse direction over a defined time frame of 1 to 90 days.
