Figure 1 Correlation between systolic pulmonary arterial (PA) pressure and indexed mitral valve effective orifice area. An indexed mitral valve effective orifice area  1.2 cm2/m2 afforded the best sensitivity and specificity for the prediction of PA hypertension defined as a systolic PA pressure >40 mm Hg (thin lines).
