An electro-anatomical map is generated from first position information that defines an initial map surface. Second position information is acquired and used to determine an updated map surface. A difference between the initial and updated map surfaces corresponds to a change in the map. A first tenting analysis volume is determined based on at least part of the updated map surface. Third position information is acquired and used to define a second tenting analysis volume. The change in the map is identified as potentially corresponding to tenting in accordance with whether the first tenting analysis volume fails to overlap a predetermined amount with the second tenting analysis volume.

Automated tool for identifying and correcting tenting artifacts in anatomical mapping

A system includes a display and a processor. The display is configured to display at least a map of an organ having tissue including first and second surfaces that are facing one another. The processor is configured to: (i) receive a first position of a first lesion formed by ablating the first surface, (ii) calculate on the second surface, a second position that is facing the first position, and (iii) display, over the map, a marker indicative of the second position for guiding a user to produce in the tissue a second lesion facing the first lesion.

Applying ablation signals to both sides of tissue

A method is provided. The method is implemented by a device orientation engine being executed by one or more processors. The method includes determining a movement between each electrode group of a catheter to provide movements and determining a total movement of electrodes of the catheter. The method also includes removing a standard component from the movements and the total movement and outputting a movement indication for the catheter based on the movements and the total movement with the standard component.

Signal analysis of movements of a reference electrode of a catheter in a coronary sinus vein

Systems and methods are disclosed for linking a point-list to a three-dimensional anatomy of the heart. Techniques disclosed include recording a point-list, where each entry in the point-list comprises data elements, and is associated with a location in the heart and a measurement. The associated measurement is acquired by an electrode of a catheter that is placed at the associated location in the heart. Techniques disclosed further include selecting one or more anchor points associated with a region of interest in the heart, then, for each entry in the recorded point-list, computing a data element of distance between the entry's associated location in the heart and the selected one or more anchor points, and manipulating entries in the point-list based on their respective data elements.

Point-list linking to three-dimensional anatomy

A method includes presenting, on a display, an electroanatomical (EA) map of a surface of a cavity of an organ. Input is received from a user, and, in response to the user input, a region of the EA map is locked to subsequent updates.

Fast anatomical mapping (FAM) reconstruction using surface update restrictions

A system and method for clustering wavefront signals in an electrophysiological map of a cardiac tissue are provided. The system and method include receiving an electrophysiological map of the cardiac tissue, displaying propagation of the wavefront signals as a plurality of velocity vectors, discretizing the received electrophysiological map into a plurality of sections, clustering the velocity vectors into at least one group within each section based on predefined criteria, and generating a trend line representative of each group of clustered velocity vectors within each section in the electrophysiological map.
