Meta Analysis Comparative StudyLong-term outcomes of mechanical versus biological aortic valve prosthesis: Systematic review and meta-analysis.
In recent years, the use of surgically implanted biological aortic valves has been favored over mechanical prosthesis in patients between 50 and 70 years of age. However, outcomes on long-term survival are contradictory. The objective of this study was to determine if patients with mechanical valves have worse long-term survival than patients with biological prostheses. ⋯ Compared with biological aortic valves, mechanical valves are associated with a long-term survival benefit for patients between 50 and 70 years.
