Huge Pericardial Effusion in Neglected Adolescent with Parachute Mitral Valve — A Case Study

Introduction: Pericardial effusion is defined as progressive rise in the fluid content between the two pericardial layers which cause expansion of pericardial space. These pathological changes could be happened as a result of many conditions like cardiac surgery and inflammations. Cardiac tamponade is a critical condition that occurs after sudden and/or excessive accumulation of fluid in the pericardial space that restricts appropriate filling of the cardiac chambers disturbing normal hemodynamics and ultimately causing hypotension and cardiac arrest. This critical situation must be diagnosed and treated as early as possible to prevent life threating conditions. Case study: Here, we study a case of chronically neglected patient with parachute mitral valve presented with huge pericardial effusion. Discussion: There are too many studies done about the cause of pericardial effusion, we need to expand our work supported with current knowledge to understand the etiology and to individualized the treatment according to different causes by directing our plan to that point. Conclusion: We have to consider several issues in management a case of pericardial effusion like history and clinical picture to be correlated with imaging and laboratory findings especially inflammatory markers.
