MedTech West lunch seminar: Non-invasive localization of cardiac arrhythmia substrates – is magnetocardiography the solution?
Welcome to a MedTech West lunch seminar with Lennart Bergfeldt, professor and senior Consultant in Cardiology at Sahlgrenska Academy and Sahlgrenska University Hospital. Some arrhythmias (heart rhythm disturbances) have distinct anatomical origins. This is most obvious for congenital muscle bridges between atrium and ventricle (accessory pathways or electrical short-cuts) and extra-beats from the ventricles (ventricular premature beats or extrasystoles). Applying catheter based invasive techniques, such arrhythmia substrates can often be destroyed (ablated) either by heating (radio-frequency technique) or by freezing (cryo-ablation). An accurate non-invasive localization of the arrhythmia substrate before the invasive ablation procedure would facilitate the decision on optimal strategy in difficult cases and thereby possibly improve success rate, minimize the risk for the patient, and reduce procedure time. The vision would be a completely non-invasive localization and energy application procedure for curing cardiac arrhythmias, similar to the emerging magnetic resonance-guided focused ultrasound (MRgFUS) for certain brain disorders. The seminar starts with a presentation of personal experience of magnetocardiography with the Siemens’ Krenikon equipment at Karolinska University Hospital during the 1990’ies and a brief review of potential cardiological applications. Lennart Bergfeldt MD PhD is a Professor and Senior Consultant in Cardiology at Sahlgrenska Academy & Sahlgrenska University Hospital here in Gothenburg. A light lunch will be served to those who have registered before 1 pm. on January 18.
