Noncontrast transcatheter aortic valve implantation technique with balloon-expandable prostheses

The introduction of transcatheter aortic valve implantation (TAVI) signaled a paradigm shift for treating patients with severe aortic valve stenosis (AS). With growing expertise as well as continuous technical innovation, the procedure now presents a cornerstone in interventional treatment. Advanced fast-track pathways have further increased the safety of preprocedural, periprocedural, and postprocedural phases and reduced the median hospitalization time significantly.1 Recent studies have focused primarily on low and intermediate surgical risk patients with severe aortic valve stenosis.
