A catastrophic nightmare of the interventional cardiologist: Iatrogenic left main artery dissection and longitudinal stent deformation.

Iatrogenic left main coronary artery dissection is a rare but potentially life-threatening complication of invasive coronary procedures. The newer generation drug eluting stents have shown a greater safety and efficacy compared to first generation drug eluting stents. We report a 60-year-old woman with iatrogenic left main coronary artery dissection who failed bailout stenting and underwent coronary artery bypass grafting. The strategy for managing left main coronary artery dissection is variable and depends upon the mechanism, the comorbidities of the patient and degree of hemodynamic stability. Longitudinal stent deformation is a rarely encountered complication but can be seen in complex lesions such as ostial, bifurcation and left main coronary artery lesions. The interventionists must be aware of this complication.
