Usefulness of Cardiac Magnetic Resonance Imaging to Measure Left Ventricular Wall Thickness for Determining Risk Scores for Sudden Cardiac Death in Patients With Hypertrophic Cardiomyopathy
Echocardiography-derived measurements of maximum left ventricular (LV) wall thickness are important for both the diagnosis and risk stratification of hypertrophic cardiomyopathy (HC). Cardiac magnetic resonance (CMR) imaging is increasingly being used in the assessment of HC; however, little is know...

There was poor agreement on the location of maximum LV wall thickness; weighted-Cohen's κ 0.14 (p = 0.036) and maximum LV wall thicknesses were systematically higher with echocardiography than with CMR (mean 19.1 ± 0.4 mm vs 16.5 ± 0.3 mm, p <0.01, respectively); Bland-Altman bias 2.6 mm (95% confidence interval −9.8 to 4.6). Interobserver variability was lower for CMR (R2 0.67 echocardiography, R2 0.93 CMR). The mean difference in 5-year sudden cardiac death (SCD) risk between echocardiography and CMR was 0.49 ± 0.45% (p = 0.37).
