title: Transcatheter aortic valve implantation: our vision of the future.
abstract: Transcatheter aortic valve implantation (TAVI), introduced 10 years ago by Alain Cribier, has now been performed in more than 50,000 patients worldwide. Our vision of the main directions for the future are fourfold. Firstly, the 'Heart Team' is and will remain, essential for patient selection and the performance of the procedure. Careful training and controlled diffusion of the technique to medico-surgical centres are also keys to success. Secondly, patient selection must be refined, in order to predict the risk of surgery and that of TAVI. The technique is currently limited to very high-risk patients or those with contraindications to surgery. It will be extended to include lower risk patients once there are adequate trial data, the safety of the procedure has been improved and better knowledge of long-term outcomes from the procedure has been obtained. Thirdly, the procedure will be simplified, and should also be safer with an expected decrease in the occurrence of strokes, vascular complications and perivalvular regurgitation. Fourthly, the devices will also improve, with the addition of the potential for repositioning and improvement in durability. The role of imaging with the use of multimodality techniques will no doubt increase and ease the efficacy and safety of the procedure. Overall, the use of TAVI will undoubtedly increase over time, enabling a larger number of patients with severe aortic stenosis to be treated in an effective and safe way, in complement to surgical aortic valve replacement.
