Figure 2 Right heart catheterization 2weeks before admission yielded the hemodynamic measurements below. (A) Right atrial mean pressure was 14mmHg. (B) Right ventricular pressure was 75/15mmHg. (C) Pulmonary artery pressure was 77/35mmHg with a mean pressure of 50mmHg. (D) The mean pulmonary capillary wedge pressure was 24mmHg.

Figure 3 The end-expiratory left ventricular end-diastolic pressure measured on catheterization was significantly increased at 40mmHg (arrow).

Figure 4 (Top) Transmitral Doppler echocardiography shows a peak transmitral inflow velocity of 1.1 m/sec during early filling (E, white arrowhead) and 1.4 m/sec during late filling (A, boxed arrowhead) of the left ventricle. This E/A pattern is consistent with impaired ventricular relaxation. (Bottom) Tissue Doppler echocardiography reveals a mitral annular velocity of 7.0cm/sec during early filling (e’, white arrow) and 9.0cm/sec during late filling (a’, boxed arrow). Her E/e’ ratio of 15.7 and pseudonormal filling pattern based on this modality suggest a more advanced stage of diastolic dysfunction.
