Overview
Cardiac tamponade is a life-threatening condition requiring urgent intervention to remove the pericardial fluid. Complications include pulmonary edema, cardiac failure, cardiogenic shock and ultimately death.
Cardiac tamponade has a good prognosis if detected early and treated immediately. Short-term survival is mostly dependent on early diagnosis and relief of tamponade. Long-term survival depends upon the prognosis of the underlying cause, irrespective of the mode of treatment[1].
Complications
Cardiac tamponade is a life-threatening condition requiring urgent intervention to remove the fluid from the pericardial cavity. If untreated, the patient may develop the following complications:
- Pulmonary edema due to decreased forward flow of blood from the left ventricle and increased pressures within the pulmonary vasculature.
- Cardiac failure secondary to inadequate ventricular filling and cardiac output.
- Cardiogenic shock
- Pulseless electrical activity
- Death
Prognosis
- The prognosis of cardiac tamponade depends upon tow factors:
- The underlying condition
- The speed with which the syndrome is recognized and treated.
- The prognosis of a cardiac tamponade is typically good with early recognition and management of the condition and the underlying causes of the tamponade. 3.2% of the total deaths over a 10-year period were attributable to cardiac tamponade in a postmortem study of 14,368 patients in County of Cornwall, UK between 1995 and 2004.[2]
- Cardiac tamponade caused by central venous catheters had a mortality rate of 77% before 1980 and 47% between 1980-1989[3].
- Patients with underlying malignancy has the highest rate of mortality[4]. Short-term survival is mostly dependent on early diagnosis and relief of tamponade. Long-term survival depends upon the prognosis of the underlying cause, irrespective of the mode of treatment[1].
- Tamponade secondary to idiopathic effusion and penetrating chest wounds has been shown to be associated with better outcomes with emergent removal of pericardial fluid.
