Commentary: The depth of the virtual basal ring

[摘要] The anatomic demarcation between the left ventricular outflow tract (LVOT) and the aortic root, and thus the beginning of the arterial system, is the ventriculoaortic junction (VAJ). However, in an anatomic study in human hearts, we have demonstrated that the VAJ is rather curvilinear.1 It crosses the base and insertion of the right coronary cusp and lays a few millimeters above the virtual basal ring (VBR; defined as the plane passing through the nadirs of each aortic cusp), in between the left/right and the right/noncoronary commissures.
