Aortic dissection complicating failed coronary stenting.

We present a case of coronary dissection with retrograde extension to the sinus of Valsalva and ascending aorta after transradial percutaneous coronary intervention. Sealing the entry port of the coronary dissection with a stent resulted in failure. We made careful observation of the patient s course because the dissection did not seem to progress. Abnormal staining of the false lumen disappeared within an hour and the dissection repaired itself spontaneously in a day.
