Platform Selection for Patients Undergoing Transcatheter Aortic Valve Replacement: A Practical Approach.

Transfemoral transcatheter aortic valve Replacement (TAVR) has become the standard therapy for patients with severe aortic stenosis in patients over 75 years old in Europe or 65 years old in the United States, regardless of the surgical risk. Furthermore, iterations of existing transcatheter aortic valves (TAVs), as well as devices with novel concepts, have provided substantial improvements with respect to the limitations of previous-generation devices. Hence, treatment of a broader spectrum of patients has become feasible, and a sophisticated selection of the appropriate TAV tailored to patients' anatomy and comorbidities is now possible. Anatomy, patient characteristics, and operator experience must all inform proper device selection. This review describes the features and performance of the current generation of TAVs with the aim of providing a practical approach for clinicians when selecting the appropriate TAV for a specific patient.
