Delivery plan evaluation system

A method for treating an arrhythmia of a patient, the method comprising:

• under control of one or more computing systems:
• running a lesion development simulation based on cardiac characteristics and a treatment plan that specifies a delivery plan and a target location to generate a simulated lesion having lesion characteristics;
• initializing a three-dimensional (3D) mesh representing a heart based on the cardiac characteristics, vertices of the 3D mesh associated with cardiac tissue characteristics, one or more vertices associated with cardiac tissue characteristics representing an arrhythmia source;
• adjusting the cardiac tissue characteristics of at least some of the vertices of the 3D mesh to reflect an effect of an ablation resulting in formation of the simulated lesion;
• and
• running a lesion evaluation simulation based on the 3D mesh with the adjusted cardiac tissue characteristics to determine whether the simulated lesion would be effective at treating the arrhythmia of the patient;
• and
• performing an ablation on the patient based on the delivery plan and the target location and based on the determination as to whether the simulated lesion would be effective at treating the arrhythmia of the patient.
