Aortic annulus S-curve

Sweep the C-arm with the sliders or drag directly on the plot. The live fluoroscopic view shows the three coronary cusps — RCC (green), LCC (red), NCC (yellow) — under that projection. Markers on the S-curve show the six canonical views; the three highlighted ones are most frequently used.
