Example of borderline RHD consistent with WHF 2012 criteria. A. Parasternal long-axis (PLAX) view showing thickened anterior mitral leaflet exceeding 3 mm and restricted leaflet motion in young adult study subject. B. Colour-flow Doppler interrogation of the mitral valve in the PLAX view shows a small jet of mitral regurgitation (MR) with jet length < 2 cm. C. Colour-flow Doppler interrogation of the mitral valve using the A4C view shows jet of mitral regurgitation with jet length < 2 cm. D. Continuous-wave (CW) Doppler interrogation of the MR jet showed maximum velocities exceeding < 3 m/s.
