  • Title: Echocardiography in Transcatheter Aortic Valve Replacement.
    Author: Vollema EM, Delgado V, Bax JJ.
    Journal: Heart Lung Circ; 2019 Sep; 28(9):1384-1399. PubMed ID: 30926246.
    Abstract:
    Transcatheter aortic valve replacement (TAVR) is a safe and efficient alternative for surgical valve aortic replacement in patients with symptomatic severe aortic stenosis who are inoperable or have a high risk for surgery. Randomised clinical trials have shown that TAVR is not inferior to surgical aortic valve replacement in intermediate-risk patients and ongoing trials will demonstrate the effects of TAVR in asymptomatic severe aortic stenosis patients and in patients with heart failure and moderate aortic stenosis. Continuous developments in procedural and post-procedural management along with increased operator experience and technical improvements and ongoing advances in imaging modalities (particularly in three-dimensional techniques), have reduced the procedural risks and the incidence of complications such as paravalvular aortic regurgitation. Importantly, proper selection of both patient and prosthesis, procedural guidance and follow-up of prosthesis performance remain paramount for the success of the TAVR. In all these steps, echocardiography plays a crucial role. An overview of the clinical applications and current role of echocardiographic techniques in patient selection, prosthesis sizing, periprocedural guidance and post-procedural follow-up will be provided in this review article.
