  • Catheter Ablation Guided by Real-Time MRI
    Current Cardiology Reports, 2014
    Co-Authors: Charlotte Eitel, Gerhard Hindricks, Matthias Grothoff, Matthias Gutberlet, Philipp Sommer
    Abstract:

    Real-time magnetic resonance imaging (MRI) combines the advantages of excellent soft-tissue characterization in a true 3D anatomical and functional model with the possibility of lesion and gap visualization without the need of any radiation. Therefore, real-time MRI presents a particularly attractive imaging technology to guide Electrophysiology studies and catheter ablation procedures. This article aims to provide an overview on current routine clinical application of MRI in the setting of interventional Electrophysiology. Furthermore, development of real-time MRI guided Electrophysiology studies and first experiences with MRI guided catheter ablation procedures are depicted. In this context advantages, challenges and limitations of real-time MRI guided catheter ablation as well as future perspectives are discussed.

  • Advances in Real-Time MRI–Guided Electrophysiology
    Current Cardiovascular Imaging Reports, 2019
    Co-Authors: Rahul K. Mukherjee, Henry Chubb, Sébastien Roujol, Reza Razavi, Mark D. O’neill
    Abstract:

    Purpose of Review Theoretical benefits of real-time MRI guidance over conventional Electrophysiology include contemporaneous 3D substrate assessment and accurate intra-procedural guidance and evaluation of ablation lesions. We review the unique challenges inherent to MRI-guided Electrophysiology and how to translate the potential benefits in the treatment of cardiac arrhythmias. Recent Findings Over the last 5 years, there has been substantial progress, initially in animal models and more recently in clinical studies, to establish methods and develop workflows within the MR environment that resemble those of conventional Electrophysiology laboratories. Real-time MRI-guided systems have been used to perform electroanatomic mapping and ablation in patients with atrial flutter, and there is interest in developing the technology to tackle more complex arrhythmias including atrial fibrillation and ventricular tachycardia. Summary Mainstream adoption of real-time MRI-guided Electrophysiology will require demonstration of clinical benefit and will be aided by increased availability of devices suitable for use in the MRI environment.
