[Catheter-induced dissection of the right coronary ostium and aortic root].

We describe a catheter-induced dissection of the ostium of the right coronary artery extending to the aortic root. As an alternative to emergency surgery, a dacron stent-graft was placed in the proximal right coronary artery, thus, sealing the dissection. The patient later underwent elective aortocoronary bypass surgery. The therapeutic options in this situation with diffuse coronary disease, in which only one severe culprit lesion can be identified, are discussed.
