Cardiac tamponade secondary to tension pneumopericardium
from penetrating chest trauma.
9) A life-threatening tension pneumopericardium can be a complication that can be caused by a valve mechanism that allows the air to enter the pericardial sac but not to exit it.
15) Our case elucidates the role of Valsalva's s maneuver in the pathophysiology of pneumopericardium and increases physicians' awareness of pneumopericardium as a possible cause of chest pain and to rule out tension pneumopericardium as a possible reason of hemodynamic shock, especially when no trauma is visible.
The commonest sign of tension pneumopericardium is distant, muffled heart sounds.
The primary management of tension pneumopericardium is relief of the cardiac tamponade to restore haemodynamic stability.
