SOB in a patient with cancer -- Cardiac Tamponade

[@pb5640]

there’s always an exception to the rule ...in patients actively being dialyzed, some patients who have a co-existing cardiac effusion may transform to tamponade physiology due to the dramatic circulatory volume reduction. In this scenario, their IVC may not be distended but yet they have cardiac tamponade physiology because their vascular volume has been acutely reduced and now the effusion goes unopposed .
