Positioning of self‐expanding transcatheter valve prostheses

Key Points The anatomic interplay between aortic valve, ascending aorta, left ventricular outflow tract and peripheral vasculature play a major role in determining device related outcomes in transcatheter aortic valve replacement. Factors such as the alignment angle (prosthesis—ascending aorta), pre‐dilatation, operating team experience and chronic kidney disease may play a role in valve displacement. Careful analysis of all imaging modalities while sizing and selecting a valve type, and attention to newer deployment techniques may improve outcomes.
