Abstract: The invention relates to a method for evaluating treatment-relevant spatial anatomical information among different data sets of the heart, the method comprising the steps of: —determining a reference anatomical 3 dimensional data set of the heart, —providing a first anatomical 3 dimensional data set of the heart, the first anatomical 3 dimensional data set comprising first treatment-relevant spatial anatomical information, —providing a second anatomical 3 dimensional data set of the heart, the second anatomical 3 dimensional data set comprising second treatment-relevant spatial anatomical information, —registering the reference data set to the first and the second data sets, —transferring the treatment relevant spatial anatomical information of the first and the second data set to the reference data set in order to generate a first transferred treatment-relevant spatial anatomical information on the reference data set and a second transferred treatment-relevant spatial anatomical information on the reference

Abstract: A method for compensating cardiac and respiratory motion in atrial fibrillation ablation procedures includes (a) simultaneously determining a position of a circumferential mapping (CFM) catheter and a coronary sinus (CS) catheter in two consecutive image frames of a series of first 2-D image frames; (b) determining a distance between a virtual electrode on the CS catheter and a center of the CFM catheter for a first image frame of the two consecutive image frames, and for a second image frame of the two consecutive image frames; and (c) if an absolute difference of the distance for the first image frame and the distance for the second image frame is greater than a predetermined threshold, compensating for motion of the CFM catheter in a second 2-D image.
