Why the study?
Does a biological aortic valve prosthesis compared to a mechanical prosthesis affect long-term survival and valve-related morbidity in middle-aged patients?
Does a biological aortic valve prosthesis compared to a mechanical prosthesis affect long-term survival and valve-related morbidity in middle-aged patients?
Middle-aged patients undergoing aortic valve replacement may benefit more from mechanical rather than biological prostheses due to lower long-term valve-related morbidity.
Biological prostheses associated with higher valve-related morbidity without survival difference; leaves open optimal choice in middle-aged patients pending RCTs.
While survival was not different among groups, patients with a biological prosthesis showed a higher valve-related morbidity at follow-up. Therefore, middle-aged patients should preferably receive a mechanical prosthesis.
