Structural and Non-Structural Deterioration After Biological Aortic Valve Replacement: Long-Term Outcomes of 918 High-Risk Patients

This study showed a good long-term survival of surgical AVR with biological prostheses in relatively high-risk and elderly patient population. All biological prosthetic valves showed good long-term durability with low levels of complications and reoperations. The different models did not show any significant differences. Surgical AVR remains a valuable therapeutic option even though transcatheter aortic valve implantation has been greatly expanded since its introduction.
