  • Non-invasive methods and systems for producing cardiac electrogram characteristic maps for use with catheter ablation of ventricular tachycardia
    Patent number: 9144382
    Abstract: A non-invasive method of producing a three-dimensional cardiac electrogram characteristic map for use in catheter ablation of ventricular tachycardia includes receiving left ventricle three-dimensional image data of a patient's heart; segmenting a left ventricle image of the patient's heart based on the left ventricle three-dimensional image data into scar tissue, normal myocardium tissue and left ventricle cavity regions; determining scar tissue thickness and normal myocardium tissue thickness for a plurality of portions of the left ventricle image of the patient's heart; receiving predetermined data that associate a value of at least one electrogram characteristic to each scar tissue thickness and each normal myocardium tissue thickness for the plurality of portions of said left ventricle image of said patient's heart; and generating the three-dimensional cardiac electrogram characteristic map of the at least one electrogram characteristic corresponding to the left ventricle image of the patient's heart bas

    Date of Patent: September 29, 2015
    Assignee: The Johns Hopkins University
    Inventors: Saman Nazarian, Christopher Miller, Takeshi Sasaki
