Table 3 Summary of the role of MRI in LV thickening
From: Utility of magnetic resonance imaging in the evaluation of left ventricular thickening
Disease | Role of MRI |
|---|---|
General | Establishing the presence of hypertrophy Characterizing the geometry Quantification of volumes, masses and function Establishing aetiology Fibrosis- Prognostic determinant Evaluating regression |
Systemic hypertension | Secondary causes of hypertension- renovascular, adrenal lesion |
Aortic stenosis | Planimetry- Aortic valve area Phase contrast- Quantification of stenosis Fibrosis Evaluation for TAVI |
Coarctation | Identification of coarctation/hypoplasia Quantification of narrowing Collaterals Associated abnormalities |
Subaortic membrane | Membrane- Location, size Quantification of obstruction |
Aortic/mitral regurgitation | Quantification of regurgitation Volume quantification |
Dilated cardiomyopathy | Quantification of volumes Fibrosis |
Amyloidosis | T1 kinetics and T1 mapping- Diagnosis and prognosis Late gadolinium enhancement |
Danon disease | Fibrosis |
Hypertrophic cardiomyopathy | Pattern of HCM Quantification of obstruction Mitral valve abnormalities- SAM, elongated anterior leaflet Papillary muscle abnormalities Fibrosis |
Athlete’s heart | Quantification of volumes Response to deconditioning |
Anderson Fabry disease | T1 mapping allows detection of fibrosis and lipid deposition |
Iron overload cardiomyopathy | Myocardial iron quantification |
