LAA classification with chicken-wing (A) and non-chicken-wing configurations (B–C). Chicken-wing configuration (a) is defined by a noticeable bend in the dominant lobe’s proximal or middle part. Windsock configuration (b) has a dominant lobe of sufficient length and limited width (1) and variable location and number of secondary lobes (2). Cactus configuration (c) shows a dominant central lobe (1) and varying secondary lobes (2). Compared to windsock, the dominant lobe is sufficient of width and comparatively limited in length. Cauliflower configuration (d) shows a limited length and more complex internal characteristics (2) sometimes even without a dominant lobe (1)
