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.
Cardiac MRI
- Cardiac MRL is an accurate modality for evaluation of ischemic heart disease, myocarditis, cardiomyopathic process as the precursor of ventricular arrhythmia, or SCD by finding the following:[1]
- Quantification of LVEF, left ventricular mass, and volume
- Anomaly of coronary arteries origin
- Valvular heart disease
- Myocardial scar
- Infiltrative process by late gadolinium enhancement
- LV , RV function
- Degree of fibrosis in LV, RV in HCM and ARVC
- Cardiac magnetic resonance imaging can be especially helpful in the evaluation of uncommon myocardial infiltrative diseases, such as sarcoidosis.[2][3][4]
- MRI can be useful in patients with ventricular tachycardia when echocardiography fails to provide accurate evaluation of left or right ventricular function.
