Overview
When structural heart disease is suspected in the context of ventricular tachycardia, it is necessary to have an accurate evaluation of the structure and function of the atria and ventricles. While echocardiography is the first modality of choice, MRI is used when the assessment provided by echocardiography is not satisfactory. In addition, MRI seems to have an important role in the evaluation of suspected arrhythmogenic right ventricular cardiomyopathy because MRI provides a good assessment of the right ventricular structure, function and fatty infiltration if present.
MRI
- Cardiac magnetic resonance imaging can be especially helpful in the evaluation of uncommon myocardial infiltrative diseases, such as sarcoidosis.[1][2][3]
- MRI can be useful in patients with ventricular tachycardia when echocardiography fails to provide accurate evaluation of left or right ventricular function.

| "1. MRI, cardiac computed tomography (CT), or radionuclide angiography can be useful in patients with ventricular arrhythmias when echocardiography does not provide accurate assessment of LV and RV function and/or evaluation of structural changes. (Level of Evidence B)" |
| "2. LV imaging can be useful in patients undergoing biventricular pacing. (Level of Evidence C)" |
