Extensive dissection to the coronary sinus of valsalva during percutaneous intervention in right coronary artery-a case report and literature review.

Severe retrograde dissection extending into the sinus of Valsalva is a rare complication during percutaneous coronary intervention (PCI), but life threatening. There is some literature about this complication, but this particular complication has not been previously reported in China. We present a case of coronary artery dissection during a PCI in which progressively extended retrogradely into the sinus of valsalva, and was successfully treated with stenting without an operation.
