A case of biventricular failure after pericardial window for large pericardial effusion.

Pericardial tamponade resulting in hemodynamic compromise requiring either pericardiocentesis [Vandyke 1983] or subxiphoid pericardial window has been reported in literature [Armstrong 1984]. There are no large case series, only scattered case reports. Cardiac tamponade is known to affect the diastolic function of the heart but rare reports have documented systolic impairment of the left and right ventricle in the setting of tamponade [Vandyke 1983; Armstrong 1984]. We report a case of a transient biventricular systolic dysfunction in a patient with early cardiac tamponade after surgical drainage of pericardia1 effusion.
