PG - 103-112 LID - 10.1007/s11604-017-0700-5 [doi] AB - PURPOSE: To evaluate heterogeneity of myocardial contraction in relation to extensive late gadolinium enhancement (LGE) in hypertrophic cardiomyopathy (HCM) patients with preserved left ventricular ejection fraction, using fast strain-encoded magnetic resonance imaging. MATERIALS AND METHODS: Twenty-two HCM patients and 24 age-matched control subjects were included in this retrospective study. The regional and global peak values of longitudinal and circumferential strain (LS(regional), LS(global), CS(regional), CS(global)), and their regional heterogeneities were evaluated using coefficients of variation (LS(CoV), CS(CoV)) in relation to LGE. Receiver operating characteristic curve analysis was performed to identify patients with a total left ventricular myocardial LGE >/= 15%. RESULTS: LS(global) in HCM patients was significantly decreased compared to that in controls (- 14.4 +/- 2.4% vs - 17.2 +/- 2.0%; p = 0.0004), while CS(global) was not (p = 1.0). Negative LGE segments demonstrated decreased LS(regional) in HCM patients compared to in controls (p < 0.0001), while CS(regional) was not decreased. CS(CoV) demonstrated the largest area under the curve (AUC) (0.91), with high sensitivity (83%) and specificity (94%) for detection of HCM patients with extensive LGE, while the AUC of LS(CoV) was low (0.49). CONCLUSION: The heterogeneity in CS(regional) has a high diagnostic value for detection of HCM patients with extensive LGE.
