WebNov 29, 2016 · Increased venous flow with inspiration is unable to be accommodated by a noncompliant RV; hence, there are diastolic flow reversals in the hepatic vein with inspiration. Unlike CP, there is no discordance of intracavitary and intrathoracic pressures (Figure 2). Diagnostic Evaluation Physical examination Web(1) ventricular septal shift, (2) medial mitral e', and (3) hepatic vein expiratory diastolic reversal ratio.
