Abstract

A method is described herein. The method is implemented by an optimization engine executed by a processor. The optimization engine receives data that includes performance metrics of mapping and ablation procedures. In turn, the optimization generates procedure expected outcomes for the mapping and ablation procedures based on the data and success predictions for a current ablation procedure utilizing the procedure expected outcomes. The optimization engine, also, outputs an ablation recommendation based on the success predictions.

First claim

The invention claimed is:

1 . A method for assisting in catheter-based cardiac ablation by predicting procedural success and identifying ablation targets based on patient-specific data, the method comprising:
receiving, by a processor executing stored instructions, patient-specific data comprising (i) time-series biometric data acquired during mapping and ablation procedures using an intracardiac catheter, and (ii) corresponding procedural outcome data including recurrence status or need for redo procedures; generating, by the processor, procedure performance metrics based on the patient-specific data, the performance metrics characterizing features of successful and unsuccessful ablation procedures; determining, by the processor during a current ablation procedure, a success prediction for the catheter-based cardiac ablation by applying a trained predictive model to real-time biometric signals received from the intracardiac catheter, the prediction based on the previously generated performance metrics; and generating and displaying, by the processor, an ablation recommendation comprising a predicted likelihood of procedural success and a spatial location on a cardiac anatomical model representing a recommended site for additional ablation.

2 . The method of claim 1 , wherein the data comprises anatomical and electrical measurements acquired in a portion of an atrium during the mapping and the ablation procedures.

3 . The method of claim 1 , wherein the processor receives the data from at least one sensor comprising a catheter or a body surface electrode.

4 . The method of claim 1 , wherein the data comprises long outcome results, patient demographics, procedure parameters related to the mapping and the ablation procedures, or information related to prior electrophysiology procedures.

5 . The method of claim 1 , wherein the one or more success predictions comprise a redo procedure necessity with respect to one or more ablation gaps or acute or long term outcomes for the current ablation procedure.

6 . The method of claim 1 , wherein the ablation recommendation comprises an area for ablation based on the one or more success prediction and a probability for a redo procedure.

7 . A system for assisting in catheter-based cardiac ablation by predicting procedural success and identifying ablation targets based on patient-specific data, the system comprising:
a memory storing computer-readable instructions; and one or more processors in communication with an intracardiac catheter, wherein the computer-readable instructions: when collectively executed by the one or more processors cause the system to: receive patient-specific data comprising (i) time-series biometric data acquired during mapping and ablation procedures using the intracardiac catheter and (ii) corresponding procedural outcome data that include recurrence status or need for redo procedures; generate procedure performance metrics from the patient-specific data, the procedure performance metrics characterizing features of successful and unsuccessful ablation procedures; during a current ablation procedure, determine a success prediction for the procedure by applying a trained predictive model to real-time biometric signals received from the intracardiac catheter, the success prediction being based on the generated procedure performance metrics; and generate and display an ablation recommendation that includes a predicted likelihood of procedural success and a spatial location on a cardiac anatomical model representing a recommended site for additional ablation.

8 . The system of claim 7 , wherein the data comprises anatomical and electrical measurements acquired in a portion of an atrium during the mapping and the ablation procedures.

9 . The system of claim 7 , wherein the one or more processors receive the data from at least one sensor comprising the catheter or a body surface electrode.

10 . The system of claim 7 , wherein the data comprises long outcome results, patient demographics, procedure parameters related to the mapping and the ablation procedures, or information related to prior electrophysiology procedures.

11 . The system of claim 7 , wherein the one or more success predictions comprise a redo procedure necessity with respect to one or more ablation gaps or acute or long term outcomes for the current ablation procedure.

12 . The system of claim 7 , wherein the ablation recommendation comprises an area for ablation based on the one or more success prediction and a probability for a redo procedure.

13 . A non-transitory computer readable storage medium storing instructions for assisting in catheter-based cardiac ablation by predicting procedural success and identifying ablation targets based on patient-specific data, the instructions when executed by a processor of a surgical console, cause the surgical console to perform a method comprising:
receiving patient-specific data comprising (i) time-series biometric data acquired during mapping and ablation procedures using an intracardiac catheter, and (ii) corresponding procedural outcome data including recurrence status or need for redo procedures; generating procedure performance metrics based on the patient-specific data, the performance metrics characterizing features of successful and unsuccessful ablation procedures; determining, during a current ablation procedure, a success prediction for the catheter-based cardiac ablation by applying a trained predictive model to real-time biometric signals received from the intracardiac catheter, the prediction based on the previously generated performance metrics; and generating and displaying an ablation recommendation comprising a predicted likelihood of procedural success and a spatial location on a cardiac anatomical model representing a recommended site for additional ablation.
