[The worst complication during percutaneous coronary intervention: left main coronary artery dissection]

Although rare, left main coronary artery dissection is a cause of periprocedural mortality during percutaneous coronary interventions. We report a case of iatrogenic dissection of the left main coronary artery causing cardiogenic shock, treated by extracorporeal membrane oxygenation (ECMO) support and later on by multiple balloon angioplasty and drug-eluting stent deployment, due to clinical worsening despite patent left coronary arteries with preserved good TIMI flow grade. We also reviewed the management strategies of this complication reported in the literature.
