Highlights the atypical presentation of low-pressure cardiac tamponade in the setting of hypovolemia, lacking classic signs like pulsus paradoxus and jugular venous distension.
Raises awareness for atypical tamponade in hypovolemia; single case leaves open need for validation.
An elderly man developed cardiac tamponade from a tuberculous pericardial effusion but without such typical manifestations as pulsus paradoxus and jugular-vein distension. This case illustrates the difficulties in clinical recognition of low-pressure cardiac tamponade, which can develop in the presence of dehydration and hypovolemia. The hemodynamic factors that account for this phenomenon are discussed.
