Figure 2 The LVOT Stack Prescription and 2 Examples

(A) Left ventricular outflow tract (LVOT) stack prescription is created by obtaining parallel slices across the mitral valve perpendicular to the long axis of the valve. (B) The LVOT stack from a patient with A1, P1, A2, and P2 prolapses. (i) A1/P1, (ii) and (iii) A2/P2, (iv) A3/P3. (C) The LVOT stack from a patient with prolapse of all scallops and a centrally directed mitral regurgitation jet. Ao = aorta; MV = mitral valve; PA = pulmonary artery; RA = right atrium.
