Abstract

Introduction:
The aim of the study was to identify the significance of pericardial effusion and physiology of cardiac tamponade.
Case Report: We used cardiac imaging with echocardiography and cardiac computed tomography (CT) in a patient with pericardial effusion. Two-dimensional transthoracic echocardiography was used to identify the significance of pericardial effusion and 64 multi-slice, ECG retrospectively gated cardiac CT was used to confirm the physiology of cardiac tamponade. On follow-up of serial echocardiograms, there was a development of pericardial effusion and possible signs of cardiac tamponade. To confirm the significance of these findings, a cardiac CT scan was performed which showed redistribution of the pericardial effusion with respiration causing transient echocardiographic features mimicking cardiac tamponade. Conclusion: The cardiac CT scan is helpful in cases of pericardial effusion with equivocal echocardiographic features of cardiac tamponade. In asymptomatic patients, small to moderate effusions can be followed with serial echocardiograms to evaluate progression and signs of hemodynamic compromise. Although some echocardiographic features may mimic signs of cardiac tamponade, cardiac CT scan can be used to rule out hemodynamic compromise. | |
