title: Atypical hemodynamic manifestations of cardiac tamponade.
abstract: Clinical examination and transthoracic echocardiography play a vital role in the management of patients with pericardial effusion and cardiac tamponade physiology. We report patients in advanced phase 3 cardiac tamponade with variant clinical and hemodynamic presentations. These atypical cardiac tamponade cases include: A patient with severe aortic valve regurgitation who lacked pulsus paradoxus; a patient with systemic sclerosis without hypotension; and a patient with pulmonary hypertension lacking right heart collapse on echocardiography. Recognition of these atypical clinical and hemodynamic manifestations of cardiac tamponade will avoid undue delay in the treatment.
