Transcatheter aortic valve implantation

Abstract

Transcatheter aortic valve implantation (TAVI) is an established therapy for patients with symptomatic severe aortic stenosis and contraindications for surgical aortic valve replacement or with intermediate and high operative risk in whom the heart team considers that TAVI is the best therapeutic option. Accurate patient selection strongly relates on multimodality imaging consisting mostly of the combination of transthoracic echocardiography and computed tomography. To guide the procedure, fluoroscopy is the mainstay imaging modality. In the follow-up of the patients, transthoracic echocardiography and computed tomography are again the main imaging modalities to use. Cardiovascular magnetic resonance and nuclear imaging have a minimal role in this area.
