Why the study?
Use of stentless porcine bioprostheses for aortic root disease has been limited by concerns regarding long-term valve degeneration.
Does aortic root replacement with a stentless porcine bioprosthesis provide acceptable long-term survival and freedom from reoperation in patients with aortic root disease across different age groups?
Does aortic root replacement with a stentless porcine bioprosthesis provide acceptable long-term survival and freedom from reoperation in patients with aortic root disease across different age groups?
Aortic root replacement with a stentless porcine bioprosthesis demonstrates excellent 10-year freedom from reoperation (>93%) across all age groups, supporting its long-term durability.
