Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Vascular Medicine

Background:

  • Percutaneous coronary interventions (PCI) are common procedures for treating coronary artery disease.
  • Coronary artery spasm, a transient constriction of the arteries, can complicate PCI, occurring in 1-5% of cases.
  • Spasm solely induced by guidewire insertion during PCI is exceptionally rare.

Observation:

  • A case of diffuse coronary artery spasm was observed.
  • The spasm was directly attributed to guidewire insertion during the procedure.
  • The patient's condition responded rapidly to intracoronary nitrate administration.

Findings:

  • Guidewire manipulation can precipitate significant coronary artery spasm.
  • Intracoronary nitrates are an effective treatment for guidewire-induced coronary spasm.

  • Prompt recognition of this specific spasm etiology is crucial.

    • Implications:

    • Understanding guidewire-induced spasm is vital for interventional cardiologists.
    • This phenomenon influences the selection of appropriate balloon and stent sizing during PCI.
    • Awareness can prevent procedural complications and optimize patient outcomes.
