Cardiac tamponade is a serious clinical condition in which accumulation of fluid within the pericardial space increases intrapericardial pressure and restricts normal cardiac filling. Pericardial effusion is a known postoperative complication after cardiac surgery, including valve replacement procedures. Although tamponade classically presents with hypotension, dyspnea, and elevated jugular venous pressure, atypical presentations may occur. Transient visual disturbance represents an unusual manifestation and may result from reduced cerebral perfusion. We report the case of a 67-year-old man who developed recurrent episodes of transient bilateral vision loss two weeks after mechanical aortic valve replacement. Diagnostic evaluation revealed a large circumferential pericardial effusion with echocardiographic findings consistent with tamponade physiology. Urgent pericardiocentesis yielded hemorrhagic pericardial fluid with rapid clinical improvement. Anticoagulation therapy was temporarily withheld and subsequently restarted with bridging anticoagulation given the presence of a mechanical valve. This case highlights the importance of considering pericardial effusion and tamponade in postoperative cardiac patients presenting with unexplained neurologic or visual symptoms.
