FIGURE 8. Left Coronary Cusp Traversal and Snare.

FIGURE 8

Traversing the Left coronary cusp (LCC). (A) Side projection showing the LCC hinge point. (B) A sigmoid-shape coaxial crossing system combines a Long 5-F IM catheter inside a 7-F EBU guide catheter. The electrified Astato wire (red arrow) is traversing the leaflet, aimed at the left ventricular outflow tract (LVOT) snare (white arrow) stabilized by an anchor wire (blue arrow) in the left ventricular apex. (C,D) Angiography in side and en face projections, respectively, demonstrates that the traversal point is at the hinge point and midline (Online Video 3).
