Persistent bleeding into the pericardial space in the early hours after
cardiac operation not uncommonly results in cardiac tamponade. Single
chamber tamponade also might be expected, since in this setting the
pericardium frequently contains firm blood clots localized to the area of
active bleeding. However, this complication has received very little
attention in the surgical literature. We are therefore providing
documentation that isolated right atrial tamponade can occur as a
complication of cardiac operation and that there exists a potential for
misdiagnosis and hence incorrect treatment of this condition. Right atrial
tamponade may be recognized by a combination of low cardiac output, low
blood pressure, prominent neck veins, right atrial pressure in excess of
pulmonary capillary wedge pressure and right ventricular end-diastolic
pressure, and a poor response to plasma volume expansion. Findings on chest
roentgenogram and gated wall motion scintigraphy may be highly suggestive.
This review should serve to increase awareness of this complication and to
provide some helpful diagnostic clues.
