Two-Dimensional LGE or Three-Dimensional High-Resolution LGE: Role of Cardiovascular Magnetic Resonance Imaging in the Treatment of Ventricular Arrhythmias

Cardiac Magnetic Resonance-Guided Conducting Channel Delineation of an Aneurysmal Ventricular Tachycardia with the Same Circuit in the Reverse Direction."The authors carried out a successful catheter ablation of ventricular arrhythmia case by using cardiovascular magnetic resonance (CMR) imaging. 1 We would like to learn the sequence which they used and contribute to the role of CMR in the management of ventricular arrhythmias (VA).Catheter ablation is being used to treat patients with ischemic scars who are suffering from recurrent VA.Its main purpose is to locate and ablate isthmuses critical for sustaining the VA. 2 In vast majority of cases, electro-anatomical mapping (EAM) is used to delineate unipolar and bipolar low-voltage areas and to determine fragmented electrograms and late potentials.However, EAM can be a time-consuming procedure and may be hampered by inaccurate description of intramyocardial scars due to epicardial adipose tissue.
