Figure 5 Relationship Between EROA and 2D-VC Area and 3D-VC Area in Central and Eccentric MR Jets
Upper panels depict the relation of VC diameter (A) and VC area (B) to effective regurgitant orifice area (EROA) for patients with a central mitral regurgitation (MR) jet. Lower panels depict the relation of VC diameter (C) and VC area (D) to EROA for patients with an eccentric MR jet. Dotted orange lines as in Figure 4. The relation between EROA and two-dimensional (2D)-VC area was best for central MR (A). In contrast, the relation between EROA and 3D-VC area was best for eccentric MR (D).
