A rare complication during central venous catheter insertion led to cardiac arrest. A cyst prolapsed into the heart, causing electromechanical dissociation and death, highlighting procedural safety needs.

Area of Science:

  • Cardiology
  • Medical Device Complications

Background:

  • Central venous catheter (CVC) insertion is a common medical procedure.
  • Septic shock is a life-threatening condition requiring immediate intervention.

Observation:

  • A 39-year-old man presented with symptoms of septic shock.
  • During CVC insertion, the patient developed electromechanical dissociation.
  • Post-mortem examination revealed a cyst from the tricuspid valve annulus prolapsed into the right ventricular outflow tract.

Findings:

  • CVC insertion likely caused the tricuspid valve cyst to prolapse.
  • This prolapse resulted in cardiac arrest with electromechanical dissociation.
  • The patient could not be resuscitated.

Implications:

  • This case highlights a unique and fatal complication of CVC insertion.
  • Emphasizes the critical importance of preventing Seldinger wire or CVC entry into the heart.
  • Recommends confirming correct CVC placement using blood backflow, right atrial electrocardiography, and chest radiography, rather than relying solely on arrhythmias.
