Why the study?
Does cardiac magnetic resonance imaging provide different measurements of maximal left ventricular wall thickness compared to echocardiography in patients with hypertrophic cardiomyopathy?
Does cardiac magnetic resonance imaging provide different measurements of maximal left ventricular wall thickness compared to echocardiography in patients with hypertrophic cardiomyopathy?
CMR should be considered in the routine evaluation of hypertrophic cardiomyopathy due to its ability to overcome echocardiographic limitations in measuring maximal left ventricular wall thickness, which impacts diagnosis and sudden death management.
Echocardiographic LVWT underestimation in HCM subset warrants measurement caution; leaves open CMR impact on diagnosis and risk stratification.
Although maximal LVWT by echocardiography in general measured similar to CMR, discordance because of limitations in echocardiography technique was present in a significant subset of patients. As measurement of LVWT impacts diagnosis and sudden death management, CMR should be considered as part of routine evaluation of all patients with hypertrophic cardiomyopathy.
