Successful endovascular treatment of iatrogenic coronary artery dissection extending into the entire ascending aorta.

Iatrogenic acute dissection of the ascending aorta during percutaneous coronary intervention occurs rarely. Localized aortic dissections may be treated by sealing the entry with a coronary stent. However, extensive dissections may require a surgical intervention. A case of iatrogenic coronary dissection with extensive propagation into the ascending aorta during angioplasty of the right coronary artery is presented. The aortic dissection was successfully treated by stenting at the right coronary artery ostium. Follow-up computed tomography and coronary angiography showed complete resolution of aortic dissection.
