Human aortic bioprosthesis [PDF]

European Journal of Cardio-Thoracic Surgery, 2008
We have read with the greatest interest the paper by Wolfgang A. Goetz et al. entitled Truly stentless molded autologous pericardial aortic valve prosthesis with single point attached commissures in a sheep model [1]. We congratulate the authors on their achievements in the development of valve bioprosthesis.

Pulsed Cavitational Ultrasound Softening

JACC: Basic to Translational Science, 2017
The authors propose a novel noninvasive therapeutic approach for degenerative calcified bioprosthetic heart valves based on pulsed cavitational ultrasound (PCU) to improve the valvular function by remotely softening calcified stiff cusps. This study aims
