Left ventricular outflow tract and mid-cavity obstruction may cause false-positive dobutamine stress echocardiograms

Left ventricular (LV) outflow tract obstruction (LVOTO) occurs in up to 20% of patients undergoing dobutamine stress echocardiography (DSE). Mid-cavity LV obstruction occurs less commonly during DSE.
