Resume in a practical guide for radiological use, the paper of different Cardiac Magnetic Resonance Imaging (CMRI) techniques to demonstrate the typical morphological characteristics and phenotypes of Hypertrophic Cardiomyopathy (HCM). Describe the interaction between different phenotypic patterns, functional and hemodynamic consequences, and potential adverse events Revealthe different patterns of late gadolinium enhancement (LGE) and its correlation with fibrosis Discuss the emerging role of CMRI in screening, diagnosis, and risk stratification.

Hypertrophic cardiomyopathy (HCM) is the most common inherited cardiomyopathyandthe most common cause of Sudden cardiac death (SCD)in young athletes.HCM is caused by mutations in sarcomeric genes transmitted following an autosomal dominant pattern.There is agreat variability of phenotypes. The pathologic hallmarks of HCM are myofibrillary disarray, interstitial fibrosis and abnormal dysplasia of intramural coronary arterioles (microvascular dysfunction). Because the clinical manifestations and electrocardiographic findings are nonspecific noninvasive imaging modalities play amainrole indiagnosis, management and understanding pathophysiology of HCM. The use of CMRIcombined with genetic tests,reveal a...

»CMRITECHNIQUES APPLIED TOHCM CMRI tecniques let us a new perspective aboutthe frequency, management, and prognosis of HCM. CINE SSFP MR IMAGING SEQUENCES (Cine Steady-state free precession) are usedto evaluate: -Cardiac function measurement Biventricular volume quantification and function Elevation of left ventricle ejection fraction(LVEF) Sistolic disfunction often develops with end-stage HCM. Assessment of global and segmental systolic thickening -Morphological aspects: Quantify the Myocardial thickness and mass accurately which are related to the diagnosis and prognosis of HCM: Diagnostic criterion for HCM is a maximal LV wall...

MRI has proven to be an important tool for the evaluation of patients suspected of having HCM Makingthe diagnosis and identifying the phenotypes of HCM Can potentially identify the subset of patients at risk of sudden cardiac death Differentiating between HCM and other myocardial diseases showing LVH (phenocopies). playing an important role in screening of the family members of a patient with HCM. Have a practical updated management guide by CMRI, includingtechnical, clinical and pathophysiological and risk startification aspects, allows a faster and more reliable...
