A Case of Delayed Postoperative Cardiac Tamponade with Unusual Echocardiographic Findings (Part 2)

In: Postoperative Cardiac Tamponade

19 Sep 2012

Increased peak early transmitral Doppler flow velocities (1.4 m/s) were consistent with a decrease in the functional left ventricular inflow orifice secondary to atrial compression. In addition, a loculated effusion was present around the right atrium (best seen on apical and subcostal views, Fig 1 and 2), with severe right atrial compression and impairment of right ventricular diastolic filling (right ventricular peak early inflow velocity, 1.8 m/s). Color Doppler flow imaging was helpful in distinguishing the compressed atrium from the adjacent pericardial effusion by demonstrating flow from the inferior vena cava through the compressed right atrium into the right ventricle. There was no apparent respirator)’ variation in right and left ventricular inflow velocity curves. Left ventricular size and systolic function were normal. The prosthetic aortic valve and graft appeared normal, with no Doppler evidence for prosthetic valve dysfunction.
