  • Publication number: 20240115312
    Abstract: A system includes an interface and a processor. The interface is configured to receive multiple electrophysiological (EP) signals from a tissue area along an ablation curve inside a cardiac chamber of a heart of a patient. The processor is configured to (i) generate local conduction vectors (LCVs) for the area based on the multiple EP signals, (ii) estimate a level of change between sets of LCVs along the ablation curve within the tissue area, and (iii) based on the level of change, identify a presence of a conduction gap in the ablation curve.

  • Publication number: 20230404677
    Abstract: 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.

  • Publication number: 20230355159
    Abstract: A method for identifying candidate locations for ablation includes receiving an electrophysiological (EP) map comprising anatomical surface of cardiac chamber overlaid with (i) activation wave velocity vectors, (ii) data points comprising positions on surface and respective local activation times (LAT), and (iii) areas designated by early meet late (EML) LAT range. Set of shortest paths on cardiac surface is identified between different EML areas. One or more ranges of LAT values are selected, being characterized by lowest prevalence over data points of EP map. Complex tags are generated for positions having the LAT values within the one or more ranges of LAT values having lowest prevalence. Subset of the shortest paths is selected based on (i) density of complex tags along shortest paths and (ii) directions of activation wave velocity vectors relative to each of shortest paths. Selected subset of shortest paths are presented as candidate slow-conduction areas for ablation.

  • Publication number: 20230277112
    Abstract: A system for generating an electrophysiological (EP) map includes a display and a processor. The processor is configured to (i) receive multiple EP data points comprising respective locations and EP values, generated from signals acquired by one or more electrodes of a catheter that are in contact with tissue of a cardiac chamber, (ii) score the received data points with respective quality scores, (iii) for a given unit volume of the EP map, select, from among the data points whose locations fall in the unit volume, a data point with a highest quality score, for use in generating the EP map, and (iv) visualize the EP map to a user, on the display.

  • Publication number: 20230190171
    Abstract: In one example, method includes receiving an electrophysiological (EP) map of at least a portion of a surface of a cardiac chamber, the EP map including multiple EP values overlayed at multiple respective positions on the surface. A clinical input is identified, that was marked on the EP map by a user using an input device. One or more of the EP values are automatically adjusted to be consistent with the clinical input.
