FIGURE 1. Define the Annular Plane.

FIGURE 1

Mark the exact annular plane. This is an orthogonal side view (maximum intensity projection) confirming that the selected annular plane is accurate for this Magna-Ease valve. The dots on the annular nadirs (green, right coronary cusp [RC]; yellow, noncoronary cusp [NC]) overlap, and the stent posts overlap in this so-called 2:1 orientation. Left coronary artery origin is seen at 2 o’clock. Multiplanar reconstruction shows the center of rotation (3-pronged star). (Inset) example of annular plane selected for a Mitroflow bioprosthetic, which typically assumes a sigmoidal configuration after implantation; the plane should abut at the lowest 3 points. LC = left coronary cusp.
