Guidewire-induced dissection of the right coronary artery and adjacent aortic wall during percutaneous coronary angioplasty.
We describe two patients in whom right coronary artery dissection and retrograde dissection of the sinus of Valsalva occurred during guidewire advancement for percutaneous coronary angioplasty Both patients were treated successfully by coronary stenting. These cases illustrate that contrast medium injection can detect early complications during guidewire advancement for coronary intervention.
