Left Main Stem Perforation: Management Strategies in a Potentially Catastrophic Event
ABSTRACT Left main stem coronary perforation is a potentially fatal complication of percutaneous coronary intervention if not recognized early and treated emergently. Treating left main stem perforation can be challenging due to the significant hemodynamic effect of one of the important steps, namely balloon tamponade.
