Can layer-specific speckle tracking echocardiography assess right ventricular systolic function and indicate clinical risk in patients with hypertrophic cardiomyopathy?
Layer-specific speckle tracking echocardiography reveals significant right ventricular systolic dysfunction in HCM patients, which correlates with adverse clinical features.
This study revealed that absolute values of the RV systolic function decreased significantly in HCM patients, as characterized by reduced absolute values of RVGLS and RVFWS across all three myocardial layers, particularly in HCM patients with RVH. LSS of RVGLS and RVFWS could serve as indicators of increased risk for chest pain, NYHA grade, and arrhythmias.
Zhang et al. (Wed,) studied this question.
