摘要
BACKGROUND:An 84-year-old man suffering from dyspnoea on mild exertion and a 10-year history of mitral valve replacement with a mechanical prosthesis presented to our department. The patient had an isolated right aortic arch.
INVESTIGATION:Transthoracic echocardiography demonstrated severe LV systolic dysfunction (EF 25%), good function of the previously implanted mechanical prosthesis and severe aortic stenosis. Multislice computed tomography confirmed the presence of an isolated right aortic arch with mirror-image branching.
DIAGNOSIS:Severe symptomatic aortic stenosis in a patient with right aortic arch at high risk for surgical reintervention.
MANAGEMENT:Transcatheter aortic valve implantation using conventional delivery system.
