Echocardiographic tamponade in severe left ventricular dysfunction: the impact of small pericardial effusion and the absence of pulsus paradoxicus

Cardiac tamponade is a commonly encountered clinical entity. It is a clinical syndrome characterized by elevated filling pressures, pulsus paradoxicus, and eventually, hypotension. It occurs as intrapericardial pressure exceeds intracardiac pressures altering ventricular filling. Generally tamponade...

Zusammenfassung:Cardiac tamponade is a commonly encountered clinical entity. It is a clinical syndrome characterized by elevated filling pressures, pulsus paradoxicus, and eventually, hypotension. It occurs as intrapericardial pressure exceeds intracardiac pressures altering ventricular filling. Generally tamponade occurs with moderate or large accumulations of pericardial fluid that result in an increase in pericardial pressure. It is well known that rapid accumulation of relatively small volumes of fluid can cause tamponade pathophysiology. We report a less well-recognized phenomenon. In the setting of severe left ventricular dysfunction, small volumes of pericardial fluid can result in excessive intrapericardial pressure and echocardiographic tamponade in the absence of a significant pulsus paradoxicus.
