Comparison of Long-term Efficacy of Domestic TAVR vs. Corevalve
Journal: Journal of Clinical Medicine Research DOI: 10.32629/jcmr.v5i2.2325
Abstract
Aim: To assess the long-term effects of domestic valves and compare them with similar products to demonstrate non-inferiority and provide guidance for valve selection in severe aortic stenosis patients. Methods: The study comprised two parts: evaluating the long-term effects of domestic valves through follow-up data, and conducting a meta-analysis to assess the long-term efficacy of Corevalve. Results: Both valves showed high cumulative all-cause mortality and cardiac mortality rates at 5 years post-surgery, with statistically significant differences. There were also significant differences in the cumulative incidence rates of new pacemaker implantation and cardiac rehospitalization. Stroke and myocardial infarction event rates within 5 years were both below 10%, with no statistically significant differences. Conclusion: Domestic valves demonstrated favorable long-term effects, performing comparably or even superior to Corevalve in certain aspects.
