Publication number: 20230149089Abstract: A method for guiding ablation of atrial or ventricular arrhythmia in a patient's heart is provided. A digital representation of the electrical functioning of atria or ventricles of the patient's heart is generated based on imaging data of the patient's heart that reveals the presence of adipose tissue. The arrhythmias arising in the presence of the adipose tissue in the digital representation of the patients atria or ventricles are determined. The method further includes identifying, in the digital representation, ablation targets that need to be ablated to terminate determined arrhythmias; executing, in the digital representation, a mock-up of a clinical ablation procedure of the patient to determine the electrical response of the patients heart to ablating the ablation targets, and to determine whether the heart continues to generate new arrhythmias post-procedure; and generating a final set of ablation targets based on the mock-up of the clinical ablation procedure.Type: ApplicationFiled: April 6, 2021Publication date: May 18, 2023Applicant: THE JOHNS HOPKINS UNIVERSITYInventors: Natalia A.

Publication number: 20230126413Abstract: A method of assessing the brain lymphatic or glymphatic system and the glucose transporter function on blood-cerebrospinal fluid barrier (BCSFB) of a subject using D-glucose or a D-glucose analog. A spatial map is generated of water MR signals that are sensitized to changes in D-glucose or a D-glucose analog in cerebrospinal fluid (CSF) of the subject. The spatial map is observed at one or more time points before, one or more time points during, and one or more time points after, raising the blood level of the D-glucose or a D-glucose analog in the subject CSF. A difference is detected between the MR signals of the spatial map before, during, and after raising the blood level of D-glucose or a D-glucose analog. A physiological parameter associated with the brain lymphatic or glymphatic system and the glucose transporter function on BCSFB of the subject is ascertained based on the detected difference.Type: ApplicationFiled: April 7, 2021Publication date: April 27, 2023Applicants: The Johns Hopkins University, Kennedy Krieger Institute, Inc., City University of Hong KongInventors: Jiadi XU, Peter VAN ZIJL, Lin CHEN, Kannie Wai Yan CHAN, Jianpan HUANG
