Comparative Analysis of Stented Biological Prosthesis Versus Aortic Allograft in Patients With Degenerative Aortic Valve Disease

Completed
Conditions
Bioprosthesis Failure
Allograft
Registration Number
NCT07210541
Lead Sponsor
Chelyabinsk Regional Clinical Hospital
Brief Summary

The aim of the observational study is to compare safety, clinical efficacy and time-to-event survival in patients age of 60-74 years with degenerative aortic valve disease that underwent aortic valve replacement with either stented biological prosthesis or aortic allograft.

Detailed Description

Early safety included morbidity, mortality rate, freedom from any valve related complications Clinical efficacy included mid-term survival, freedom from reoperation, repeat endocarditis and other valve related complication Time-to-event analysis included freedom from all-cause and cardio-vascular mortality, freedom from stroke, major bleeding, endocarditis, structural valve deterioration and reoperation
