Catheter-induced dissection of the left main coronary artery with and without extension to the aortic root: a report of two cases and a review of the literature.

Catheter-induced left main coronary artery dissection is quite rare. We describe two cases of iatrogenic left main coronary artery dissection. In the first case, the aortic root was involved in the dissection process, and stenting of the entry point did not halt the progression of dissection. In the second case, the dissection did not involve the aortic root.
