Hemodynamic features of the freestyle aortic bioprosthesis compared with stented bioprosthesis

Background. The Freestyle prosthesis is a new stentless aortic bioprosthesis. Anticipated benefits are improved hemodynamics and increased longevity. Methods. Doppler echocardiograms were performed early and at 3 to 6 months, 1 year, and 2 years after operation in 157 patients (69 men, 88 women, age...
