Successful use of a guide wire to engage an occluded vessel following failure of conventional catheterization techniques in a patient with acute myocardial infarction.

The present report describes the case of a 43-year-old woman with acute inferior myocardial infarction, in whom the culprit vessel was posteromedially located, and various diagnostic or guide catheters could not be engaged. The culprit vessel was directly cannulated using a guide wire, which allowed for a successful coronary intervention.
