20100160765 | THERAPEUTIC SUCCESS PREDICTION FOR ATRIAL FIBRILLATION - Certain embodiments of the invention provide methods of assessing a patient's risk for atrial fibrillation (AF) recurrence after receiving treatment with an AF treatment modality, that include determining, from left atrium (LA) tissue image data of a patient, a level of a parameter that is positively proportional to an amount of unhealthy tissue in a wall of the LA of the patient; and outputting, to an output device, an indicator of a comparison between (i) the determined level and (ii) a first threshold level of the parameter, the first threshold level derived from LA tissue image data of at least one other patient, who experienced an AF recurrence after treatment with the AF treatment modality. In certain embodiments, levels of the parameter equal to or greater than the first threshold level are indicative of a significant risk of AF recurrence after treatment with the AF treatment modality. | 06-24-2010 |
20100160768 | THERAPEUTIC OUTCOME ASSESSMENT FOR ATRIAL FIBRILLATION - Certain embodiments provide a method of assessing an outcome of an ablative atrial fibrillation (AF) treatment modality administered to a patient, the method including: determining, from left atrium (LA) tissue image data of a subject patient that has undergone an ablative AF treatment with the modality, at least one of: a level of a parameter that is positively proportional or negatively proportional to an amount of ablated tissue in a wall of the LA of the subject patient; and a spatial distribution, in the LA wall, of a variable indicative of ablated LA tissue; and outputting, to an output device, a machine-readable indicator of at least one of: (i) a comparison between the determined level and a threshold level of the parameter; and (ii) a map of the spatial distribution. | 06-24-2010 |
20100298694 | STROKE RISK ASSESSMENT - Certain embodiments provide a method of assessing a risk of thromboembolic stroke in a patient. The method comprises acquiring image data and determining an indicator of a degree of fibrosis of a patient's left atrium (LA) based on the image data. The method also comprises estimating a level of risk of thromboembolic stroke of the patient based on the indicator. | 11-25-2010 |
20120215122 | ARRHYTHMIA INFORMATION MANAGEMENT - Systems and methods for managing cardiac information concerning a patient are provided. In some aspects, cardiac information objects are displayed graphically at an interface having at least two axes. Time is displayed on a first axis of the at least two axes and parameters of the cardiac information objects are displayed on a second axis of the at least two axes. Each cardiac information object is spatially associated with at least a portion of the time displayed and a parameter displayed. In some aspects, the interface advantageously allows a user to conveniently view and manage the cardiac information objects. | 08-23-2012 |
20130023862 | IMAGE-GUIDED RENAL NERVE ABLATION - A method of treating hypertension in a mammal is described, including: by focused sound energy, heating at least one nerve at a surface of a renal artery in a mammal; during the heating and by magnetic resonance imaging, repeatedly determining thermal levels in each of first and second volumetric zones of a region that includes at least a portion of the surface, the second zone being adjacent to the first zone; after determining that an indicium of a thermal level in the first zone exceeds a first threshold, and upon determining that an indicium of a thermal level in the second zone exceeds a second threshold, ceasing the heating of the at least one nerve for at least three months; and as a result of the heating, lowering a blood pressure in the mammal. | 01-24-2013 |
20140275972 | HIGH TEMPORAL RESOLUTION MONITORING OF CONTACT BETWEEN CATHETER TIP AND TARGET TISSUE DURING A REAL-TIME-MRI-GUIDED ABLATION - A method of monitoring a position of a catheter tip relative to a target tissue. The method includes steps of identifying a wall structure in the target tissue; guiding a catheter towards the wall structure; monitoring a location of the catheter; directing a navigator beam towards the wall structure; aligning the navigator beam with the location of the catheter; monitoring a position of the wall structure using the navigator beam; and determining the position of the wall structure relative to the location of the catheter. | 09-18-2014 |
20150099965 | SYSTEM FOR HIGH RESOLUTION FAST ACQUISITION MAGNETIC RESONANCE IMAGING USING A CATHETER-MOUNTED COIL - A catheter-mounted, expandable or set in position, coil for magnetic resonance imaging. The coil having a catheter sheath including an elongated tube with a central axis, the catheter sheath having an opening at an end thereof; an expandable coil including a conductive material connected to an expansion mechanism which, when deployed, maintains the expandable receive coil shape; and a cable running through the catheter sheath, the cable being electrically connected to the coil inductive loop. | 04-09-2015 |
20150238781 | IMAGE-GUIDED TISSUE ABLATION - A method of treating hypertension in a mammal is described, including: by focused sound energy, heating at least one nerve at a surface of a renal artery in a mammal; during the heating and by magnetic resonance imaging, repeatedly determining thermal levels in each of first and second volumetric zones of a region that includes at least a portion of the surface, the second zone being adjacent to the first zone; after determining that an indicium of a thermal level in the first zone exceeds a first threshold, and upon determining that an indicium of a thermal level in the second zone exceeds a second threshold, ceasing the heating of the at least one nerve for at least three months; and as a result of the heating, lowering a blood pressure in the mammal. | 08-27-2015 |
