Pulmonary-Systemic Shunt Ratio { Qp / Qs } #CCU_ECHO ================================= can be estimated by using 2-D echo and spectral Doppler measurements in patients who have intra- or extra-cardiac shunts e.g. atrial or ventricular septal defects. Qp = RVOT VTI ⋅π⋅ (RVOT2) / 2 Qs = LVOT VTI ⋅π⋅ (LVOT2) / 2 Qp/Qs Ratio = Qp / Qs Definitions ~~~~~~~~ LVOT Left ventricular outflow tract diameter (mm) LVOT VTI LVOT subvalvular velocity time integral (cm) RVOT Right ventricular outflow tract diame
