Figure 5 (A) Correlation between magnetic resonance (MR)-measured E/A and invasive mean pulmonary capillary wedge pressure (PCWP). Note absence of correlation (p = 0.99). (B) Correlation between posteroseptal MR-measured E/Ea and invasive PCWP (R2 = 0.65, p < 0.0001). (C) Bland-Altman plot of the difference between MR-estimated and catheter-measured PCWP. Horizontal lines show the mean difference between two methods ± 2 SDs. A = peak mitral velocity at atrial contraction; E = peak mitral velocity in early diastole; Ea = early diastolic tissue velocity.
