RÉSUMÉ
The term cardiac tamponade describes a condition in which the heart is compressed by an excess of fluid in the pericardial space, with resulting abnormalities of cardiac function. Cardiac tamponade is a rare cause of sudden death. It is difficult to diagnose both in living and dead. In dead diagnosis is difficult at autopsy in absences of external visible injury & in living person the symptoms of cardiac tamponade are non specific. The symptoms relate principally to the secondary circulatory embarrassment. We present the series of cases with cause of death as cardiac tamponade due to diseases & trauma. These cases demonstrate that focus should always to be given to entire vital organs like heart and possibility of tamponade should be kept in mind.
