…lesions can cause acute severe regurgitation, a left to right shunt, tamponade, or sudden loss of effective cardiac output. Their recognition is essential because treatment…

…and tissue inflammation produce extravascular compression. In the most severe form, termed no reflow, structural and functional microvascular impairment persists despite restoration of epicardial flow…

…Chest compressions in traumatic cardiac arrest In the context of cardiac tamponade, increased pressure within the pericardial sac impedes venous return to the right atrium…

…cardiopulmonary resuscitation (CPR) differ substantially from normal circumstances. The purpose of CPR is to create large variations in intrathoracic pressure by compressing, decompressing and ventilating…

…lead to increased intrapericardial pressure, which in turn affects ventricular relaxation (and thus ventricular filling). This may even lead to compression of the ventricles during…

…The increased pressure causes compression of the atria and the ventricles (particularly the former). Even small pressure elevations on the right side can compromise venous…

…It generally results from accumulation of pericardial fluid, blood, or, less commonly, a mass. Tamponade occurs when intrapericardial pressure equals or exceeds right atrial pressure…

…In patients with pericarditis complicated by constriction, symptoms and signs of right sided heart failure may predominate. Pericardial effusions associated with post infarction pericarditis are…
