Key result
Transcatheter aortic valve implantation (TAVI) achieves over 90% procedural success rates and superior 1-year survival compared with medical treatment in high-risk severe aortic stenosis.
Careful multidisciplinary evaluation and multimodality imaging are crucial for appropriate patient selection and planning in TAVI to optimize success and minimize complications.
Supports TAVI in high-risk severe AS; leaves open optimal multidisciplinary selection criteria.
Transcatheter aortic valve implantation (TAVI) is a feasible therapeutic alternative for patients with severe symptomatic aortic stenosis who are considered high risk for surgical aortic valve replacement. The clinical results of TAVI are promising, with over 90% procedural success rates and superior 1-year survival, as compared with medical treatment. Appropriate selection of patients is crucial to optimize procedural success and to minimize the complication rate. A careful multidisciplinary evaluation of clinical symptoms and assessment of aortic valve annular size and dimensions of the peripheral arteries is mandatory to plan the TAVI strategy. Multimodality imaging plays a central role in the preprocedural evaluation of patients who are candidates for TAVI. Patient selection procedure and planning strategy for TAVI will be extensively discussed in the present article.

Yiu et al. (2011) conducted a review in severe symptomatic aortic stenosis. Transcatheter aortic valve implantation (TAVI) vs. medical treatment was evaluated. Transcatheter aortic valve implantation (TAVI) achieves over 90% procedural success rates and superior 1-year survival compared with medical treatment in high-risk severe aortic stenosis.
