Magnetic resonance imaging reliably establishes the diagnosis of hypertrophic cardiomyopathy and identifies patients at greatest risk of sudden cardiac death.
This review highlights the established role of MRI in diagnosing hypertrophic cardiomyopathy, characterizing the disease, and stratifying the risk of sudden cardiac death.
Hypertrophic cardiomyopathy (HCM) is the most common inheritable cardiac disorder, with an estimated prevalence of 1:500 in the general population. Most cases of HCM are phenotypically expressed in adolescence or early adulthood but age-related penetrance with certain phenotypes is increasingly recognized. Clinical manifestations of HCM are usually the result of systolic and/or diastolic dysfunction, left ventricular outflow tract (LVOT) obstruction, arrhythmias and sudden cardiac death (SCD). In recent years magnetic resonance imaging (MRI) has become established as an important tool for the evaluation of suspected HCM as it can reliably establish the diagnosis, help distinguish HCM from other causes of left ventricular hypertrophy (LVH) and identify those patients at greatest risk of SCD. This article reviews the current status of MRI in the evaluation of the HCM patient including imaging protocols, disease characterization and the emerging role of MRI for risk stratification and proband screening.
Hoey et al. (Wed,) conducted a review in Hypertrophic cardiomyopathy. Magnetic resonance imaging (MRI) was evaluated. Magnetic resonance imaging reliably establishes the diagnosis of hypertrophic cardiomyopathy and identifies patients at greatest risk of sudden cardiac death.
