Abstract

Although rare, iatrogenic aortocoronary dissection is one of the complications most dreaded by the interventional cardiologist. If not managed promptly, it can have redoubted and serious consequences. Herein, we present the case of a 70 year-old woman who was treated by stenting of the second segment of the right coronary artery (RCA) for recurrent angina but, unfortunately, the procedure was complicated by anterograde dissection of the RCA with a simultaneous retrograde propagation to the proximal part of the ascending aorta. Successful stenting of the entry point was able to recuperate the RCA and to limit the retrograde propagation to the ascending aorta, but there was an extension of the dissection to the aortic valve leaflets resulting in a massive aortic insufficiency. Therefore, surgical aortic valve replacement with prosthetic tube graft was performed [corrected].
