Claim:
1. System for positioning an artificial heart valve at the anatomic position of a malfunctioning heart valve of a heart of a patient, the system comprising: a valve fixation device, for fixing said artificial heart valve at said anatomic position; a valve replacement catheter, said valve replacement catheter bearing said artificial heart valve and said valve fixation device, at the tip of said valve replacement catheter, said valve replacement catheter being employed for fixing in place said artificial heart valve; a first medical positioning system (MPS) sensor located at the tip of said valve replacement catheter; an MPS coupled with said first MPS sensor, for determining the current position of said tip of said valve replacement catheter in an MPS coordinate system, according to an output of said first MPS sensor; a processor coupled with said MPS, said processor being configured to determine a trajectory along which said valve replacement catheter will move by acquiring position readings of a second MPS sensor disposed in a mapping catheter and coupled to said MPS; and a first user interface, coupled with said processor, for receiving a marking input from a user, independent of said trajectory and respective of said anatomic position, said marking input comprising at least position information indicative of said anatomic position and a marking information indicating that the user has affirmatively designated the position information as indicative of said anatomic position; said processor determining said anatomic position in said MPS coordinate system, according to said marking input; said processor constantly determining said current position, while said valve replacement catheter is moving along said trajectory toward said anatomic position; said processor producing an indication via said first user interface, when said processor determines that said current position substantially matches said anatomic position.
