title: A Retrograde Approach to Coronary Ostial Stenosis after a Bentall Procedure in a Patient with Behçet's Disease.
abstract: We describe a case of chronic total occlusion of the right coronary artery ostium 5 months after a repeated Bentall procedure in a patient with Behçet's disease. In this patient, an antegrade approach to delivering the guidewire during percutaneous coronary intervention was not successful. Coronary angiography revealed the existence of collateral blood supply from the left coronary artery. Using a retrograde approach, a guidewire was successfully advanced from the distal left circumflex artery through the collateral vessel and into the posterolateral branch of the right coronary artery. After the guidewire crossed over the occluded right coronary artery ostium and was snared into the ascending aorta, antegrade access for balloon and stent delivery succeeded.
