Figure Lengend Snippet: In vitro hemodynamic results of TAVI Valve-in-Valve implantation of Portico 23 in Trifecta GT 19 and Trifecta GT 21 prostheses in aligned and misaligned configurations in rest and exercise simulated conditions. The prostheses were implanted in aortic root models with geometries considered clinically as high risk for coronary occlusion. All data are presented as mean ± standard deviation ( p value with respect to baseline for the same heart rate and aortic root model)
