TAVI in complex clinical and anatomical scenarios

Prefazione di Antonio Colombo. Transcatheter aortic valve implantation (TAVI) was introduced about 15 years ago as an alternative to surgical valve replacement in patients at prohibitive operating risk, and is now a consolidated treatment also for lower surgical risk categories of patients. An increasing use of TAVI in even lower risk categories and to younger people is expected shortly. This makes mandatory the search for optimal procedural results. To the achievement of this goal certainly contributed the increasing experience of the operators and the enormous technological improvement, with the development of more performing prostheses with a lower profile, which drastically reduce the risks of periprocedural complications. Yet, complex clinical and anatomical features may still deeply affect the immediate and log-term outcomes after TAVI. This book was designed to address these complex scenarios, with the main objective of providing useful insights from and to expert interventional cardiologists to further optimize clinical outcomes in patients undergoing TAVI.
