AI Technical Summary
Technical Problem
Existing minimally invasive heart valve implantation techniques, such as TAVI, often result in paravalvular leaks due to imperfect positioning of the artificial heart valve, necessitating additional surgical procedures and posing risks to patient health.
Method used
A heart valve prosthesis implantation device incorporating an ICE catheter with ultrasound imaging and navigation system for precise positioning, allowing real-time monitoring and control of the heart valve prosthesis insertion, eliminating the need for subsequent corrections.
Benefits of technology
Enhances the reliability and precision of heart valve implantation, preventing paravalvular leaks and reducing the need for follow-up treatments by ensuring accurate placement of the prosthetic valve.

Abstract
Heart valve prosthesis implantation apparatus (10), comprising: - a prosthesis catheter (11) with a heart valve prosthesis (12) to be implanted, - an ICE catheter (9) - for insertion into a surrounding area of a heart valve (HC) to be treated, - for detecting a relative position (RPHC) and / or a relative orientation direction (ROHC) of the heart valve (HC) to the ICE catheter (9) by means of an ultrasound image (USHC) of the heart valve (HC) through the ICE catheter (9), and - preferably for performing ultrasound images (USPC) of the prosthesis catheter (11), wherein the ICE catheter (9) is configured to determine an absolute reference position (ARPHC) and / or an absolute reference orientation direction (AROHC) of the heart valve, 2D ultrasound images in multiple planes, and / or 3D ultrasound images of the heart valve (HK) to create- a navigation system (51) for determining an absolute position (APICE) and an absolute orientation direction (AOICE) of the ICE catheter (9), - a control device (52) for controlling the insertion of the heart valve prosthesis (12) into the annulus of the heart valve (HC) based on the ultrasound images (USHK, USPK, USHKP) of the ICE catheter (9) and position and orientation direction information (APICE, AOICE, APPK, AOPK, APHKP, AOHKP) from the navigation system (51), - a display (53) for simultaneously displaying information (APHKP, AOHKP) regarding the position and / or orientation of the heart valve prosthesis (12) and the 2D ultrasound images and / or 3D ultrasound images for monitoring the insertion of the heart valve prosthesis (12) into the annulus of the heart valve, wherein the control device (52) is set up toto verify the correct insertion of the heart valve prosthesis (12) based on a comparison of the current position (APHKP) and / or the current orientation direction (ORHKP) of the heart valve prosthesis (12) with the determined absolute reference position (ARPHK) and the reference orientation direction (AROHK) of the heart valve (HC).
