Coronary Artery Perforation Spilling into Right Ventricle: A Rare Complication of Percutaneous Coronary Intervention.

: Injury to the coronary circulation during percutaneous interventions is an existent risk. One of these is coronary artery perforation that can have grave consequences. Fortunately, this is rare and overall there is a declining incidence of complications due to technological advances and extensive experience over time. Predictors of coronary artery perforation include the administration of glycoprotein IIb/IIIa inhibitors, the use of hydrophilic guide wires, and the use of noncompliant high-pressure intracoronary balloons. Complex coronary lesions and the presence of total chronic occlusion are additional risk factors. In this paper, we present a rare class III coronary artery perforation with spilling into the right ventricle. Our case exemplifies all the aforementioned risk factors for perforation. The perforation was successfully sealed with a polytetrafluoroethylene covered stent and the patient remained hemodynamically stable.
