This study demonstrated adequate cut-off value of 3DE-derived ALVOT to diagnose LVOT obstruction in a large number of patients with HCM. This finding supported that 3DE would be the diagnostic tool of choice for the assessment of LVOT obstruction in clinical practice, especially in HCM, for which pressure gradient through LVOT is difficult to determine.
