Abstract

A prosthetic cardiac valve implantation arrangement is described. The prosthetic cardiac valve implantation arrangement includes a prosthesis catheter with a prosthetic cardiac valve to be implanted; and an ICE catheter for introduction into area surrounding a cardiac valve to detect a relative position and/or relative direction of orientation of the cardiac valve with respect to the ICE catheter with the aid of an ultrasound image of the cardiac valve recorded by the ICE catheter. In addition, a navigation system is for determining an absolute position and an absolute direction of orientation of the ICE catheter; and a control facility is for controlling the insertion of the prosthetic cardiac valve into the annulus of the cardiac valve on the basis of the ultrasound image recordings of the ICE catheter and positional and/or orientation-direction information from the navigation system. Also described is a method for monitoring a catheter-based prosthetic cardiac valve implantation.
