Pericardiocentesis

obovis

Synonym(s): Cardiac tamponade aspiration


Introduction

  • There is a potential space between the myocardium and the pericardium (the pericardial sac).
  • This may become distended with fluid.
  • Pressure within the pericardial sac compromises cardiac function (cardiac tamponade) - particularly by causing collapse of the thinner-walled right ventricle.
  • Cardiac tamponade → acute congestive heart failure.

Uses

  • Drainage of pericardial fluid.
  • Septic pericarditis (ie secondary to traumatic Reticulitis Reticulitis/ wire/ nail etc). A penetrating foreign body, originating from the reticulum, is almost always the cause of pericarditis in cattle.
  • Idiopathic pericardial effusion (hemorrhage). Cardiac tamponade
  • Pericardial/heart base tumors  → transudation or hemorrhage .

Advantages

  • Life-saving.
  • Minimally invasive procedure when correctly performed.
  • Produces rapid benefit to patient.

Disadvantages

  • Risk of lacerating myocardium or coronary arteries.
  • May be unable to drain all fluid from pericardial sac.
  • Risk of recurrence of fluid accumulation.

Prognosis

  • Guarded/poor prognosis for septic Pericarditis Pericarditis and neoplasia. Usually just a salvage procedure or short term solution to try to get a dam, carrying a valuable calf, to the point of parturition.
  • Good for resolution of clinical signs acutely.
  • Pericardial effusion may recur weeks to years later if idiopathic.
  • Prognosis following repeated drainages is less good.
