Method and apparatus for visually supporting an electrophysiological catheter application in the heart by means of bidirectional information transfer

A method for visually supporting an electrophysiological catheter application in a heart of a patient during a medical procedure, comprising:

• recording a 3D image data of the heart using a tomographic 3D imaging method;
• determining a contour of an area relative to the catheter application in the 3D image data;
• executing the catheter application;
• capturing and displaying an electroanatomical 3D mapping data of a region of the heart to be treated during executing the catheter application;
• assigning the contour to the electroanatomical 3D mapping data positionally and dimensionally correctly;
• overlaying the contour into a visual representation of the electroanatomical 3D mapping data as a single polyline;
• and
• displaying the visual representation of the electroanatomical 3D mapping data with the overlaid polyline.

A method for visually supporting an electrophysiological catheter application in a heart of a patient in a medical procedure, comprising:

• recording a 3D image data of the heart using a tomographic 3D imaging method;
• executing the catheter application;
• capturing and displaying an electroanatomical 3D mapping data of at least a region of the heart to be treated during executing the catheter application;
• determining a contour of an area from the electroanatomical 3D mapping data;
• assigning the contour to the 3D image data positionally and dimensionally correctly;
• and
• overlaying the contour into a visual representation of the 3D image data as a single polyline;
• and
• displaying the visual representation of the 3D image data with the overlaid polyline.

An apparatus for visually supporting an electrophysiological catheter application in a heart of a patient in a medical procedure, comprising:

• an electroanatomical 3D mapping system that captures and displays an electroanatomical 3D mapping data of at least a region of the heart of the patient to be treated;
• a 3D visualization workstation that displays a 3D image data of the heart of the patient;
• and
• a data link that connects the electroanatomical 3D mapping system and the 3D visualization workstation,
• wherein the 3D visualization workstation comprises a determination module that determines a contour of an area relative to the catheter application in the 3D image data and a transfer module that transmits the contour of the area to the electroanatomical 3D mapping system via the data link,
• wherein the electroanatomical 3D mapping system comprises a visualization module that overlays the transferred contour as a single polyline into a representation of the 3D mapping data positionally and dimensionally correctly based on a 3D-3D registration.
