title: Thrombus formation after aortic valvular replacement using Björk-Shiley valve occluding the right coronary orifice.
abstract: We describe a patient with unstable angina due to occlusion of the orifice of the right coronary artery by thrombus formation after aortic valvular replacement using a Björk-Shiley valve. After strict anticoagulant treatment, transesophageal echocardiography demonstrated disappearance of the thrombus formation around the orifice of the right coronary artery.
