Cardiac tamponade is diagnosed when fluid builds up within the pericardial sac, exerting pressure on the heart from the outside, reducing cardiac output and threatening the body's blood supply.1 Despite the vague nature of the symptoms, patients typically report dyspnea and chest discomfort. 2 Low blood pressure, fast heart rate, shallow breathing (tachypnea), elevated venous pressure in the jugular vein (pulsus paradoxus), and muffled heart sounds on cardiac auscultation are other clinical symptoms. But it’s rare to be seen in post esophagectomy patients as a result of gastrointestinal Obstruction.
