To the Editor Mr Chiang and colleagues1 reported that patients aged 50 to 69 years who underwent aortic valve replacement had comparable 15-year survival with implantation of a bioprosthesis or a mechanical prosthesis, suggesting that bioprosthetic valves “may be a reasonable choice” in patients aged 50 years or older. We recognize that, in part because of the advent of transcatheter aortic valve implantation and the possibility of placing a transcatheter heart valve in bioprosthetic valves with structural valve deterioration,2 bioprostheses are becoming a more attractive alternative to mechanical prostheses.3 However, additional data are required before lowering the age cutoff for implanting bioprostheses can be justified.
