Embodiment Construction

[0043] figure 1 is a schematic diagram of a prosthetic heart valve implantation device 10 according to an exemplary embodiment of the present invention. The prosthetic heart valve implantation device 10 includes a navigation system 51 which is arranged, for example, outside the patient's body. The prosthetic heart valve implantation device 10 also includes an ICE catheter 9 which is inserted into the ventricle assigned to the heart valve HK to be treated. The ICE catheter 9 is also configured to record ultrasound images US from the interior of the heart, in particular the heart valve HK to be treated HK . By means of the evaluation unit 52a (which is in figure 1 In the exemplary embodiment shown is part of the control facility 52, which is part of the prosthetic heart valve implantation device 10), the ultrasound image US HK Can be used to determine the relative position RP of the heart valve HK relative to the ICE catheter 9 HK and relative alignment to RO HK basis (see...

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.

Description

technical field [0001] The invention relates to a prosthetic heart valve implantation device. The invention also relates to a method for monitoring the implantation of a catheter-based prosthetic heart valve. The invention also relates to the use of a prosthetic heart valve implantation device. Background technique [0002] The human heart is composed of four chambers in total, namely, the right atrium, right ventricle, left ventricle, and left atrium. Deoxygenated blood is pumped into the right atrium through the superior and inferior vena cava, and from the right atrium through the first heart valve (tricuspid valve) into the right ventricle. Deoxygenated blood passes from the right ventricle through the second heart valve (pulmonary valve) into the pulmonary artery. When blood takes in oxygen from the lungs, it flows through the pulmonary veins to the left atrium of the heart. The oxygenated blood then passes through the third heart valve (the mitral valve) into the l...
