Magnetocardiography as a Noninvasive Diagnostic Strategy for Identifying Coronary Allograft Vasculopathy

Purpose: To show early feasibility of magnetocardiography (MCG) to identify coronary Cardiac positron emission tomography (PET) is the preferred non-invasive tests to assess for CAV and incorporation of quantitative myocardial blood flow (MBF) assessment improves diagnostic accuracy. Based on ISHLT criteria, the following have been proposed for diagnosis of CAV by PET:

Inclusion Criteria:≥ 18 years of age at the time of enrollmentWilling to provide written informed consentCompleted cardiac PET within the last 2 weeksNo changes to medication or intervention since the PET was completedExclusion Criteria:Patients unable to fit into devicePatients unable to lie supine for 5 minutesPatients with implanted ferromagnetic objects above the costal margin of the rib cage (implanted pacemakers, cardioverter/defibrillators, infusion pumps, and/or neuro stimulators).NOTE: Sternotomy wires stents are acceptableImplanted pacemakers or cardioverter/defibrillatorsImplanted infusion pumps and/or neuro stimulatorsSevere claustrophobia
