Transcatheter aortic valve implantation using a conventional delivery system is feasible in patients with severe aortic stenosis and an isolated right aortic arch.
Supports TAVI feasibility in right aortic arch; hypothesis-generating and requires confirmation before broader adoption.
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.

D’Ascenzi et al. (2014) conducted a case report in Severe symptomatic aortic stenosis with right aortic arch (n=1). Transcatheter aortic valve implantation (TAVI) was evaluated. Transcatheter aortic valve implantation using a conventional delivery system was utilized to treat an 84-year-old man with severe symptomatic aortic stenosis and a right aortic arch.
