35 Possible Causes for Pulsus Paradoxus, Superior Vena Cava Syndrome

  • Chronic Constrictive Pericarditis

    This situation, termed “pulsus paradoxus,” is the classic hallmark of cardiac tamponade.[aafp.org] Pulsus paradoxus, a finding in cardiac tamponade, is uncommon [ 2 ] .[patient.info] Pulsus paradoxus is a variable finding. If present, it rarely exceeds 10 mm Hg unless a concomitant pericardial effusion with an abnormally elevated pressure exists.[emedicine.medscape.com]

  • Cardiac Tamponade

    Additionally, there is a case report of tamponade during attempted stent placement in superior vena cava (SVC) syndrome (5).[web.archive.org] Pulsus paradoxus Pulsus paradoxus (or paradoxical pulse) is an exaggeration ( 12 mm Hg or 9%) of the normal inspiratory decrease in systemic blood pressure.[emedicine.medscape.com] 3.3; 95% CI, 1.8-6.3), while a pulsus paradoxus of 10 mm Hg or less greatly lowers the likelihood (likelihood ratio, 0.03; 95% CI, 0.01-0.24).[scholar.harvard.edu]

  • Hemopericardium

    Local vascular invasion may result in cerebral ischemia, myocardial infarction, and superior vena cava syndrome [ 1 ].[diagnosticpathology.biomedcentral.com] Other observable signs include rapid heart rate, jugular venous distension, low blood pressure, and pulsus paradoxus.[en.wikipedia.org] A superior vena cava obstruction syndrome may be seen. When dissection involves the distal aorta, it often involves the renal arteries. Urgent repair is required.[patient.info]

  • Mediastinopericarditis
