**5.2 Left ventricular outflow tract (LVOT)**

As described earlier, LVOT is wedged anteriorly and is narrow when compared to the aortic valve, irrespective of the type of AV septal defect. In partial form, where the superior bridging leaflet is attached to the crest of the septum, it is markedly narrow (**Figure 6**). This abnormality has been described as goose-neck deformity.
