Acute left ventricular failure after large volume pericardiocentesis.

Area of Science:

• Cardiology
• Cardiac Physiology

Background:

• Pericardiocentesis is a procedure to drain fluid from the pericardial sac.
• Large volume pericardiocentesis involves removing significant amounts of pericardial fluid.

Observation:

• Two cases presented with severe acute left ventricular (LV) systolic failure post-large volume pericardiocentesis.
• Patients had no prior history of LV dysfunction.

Findings:

• The primary hypothesis for acute LV failure is interventricular volume overload.
• An alternative hypothesis suggests increased LV wall stress due to rapid chamber distention and altered venous return.

Implications:

• Understanding these mechanisms is crucial for managing patients undergoing pericardiocentesis.
• Further research may refine management strategies to prevent or mitigate this complication.
