Assessment of the left ventricular outflow tract diameter (LVOTd) in the LV inflow–outflow tract view during early systole, as identified by cardiac MRI. Note the two parallel lines in LVOT. The upper line represents the LVOTd, whereas the lower one represents an orientation line to designate the mid-point of the lower border of LVOT. The transversal line connects the mid-points of LVOT and aortic root and is perpendicular to the line of assessment of LVOTd.
