About this trial
The goal of this multicenter prospective cohort study is to evaluate the long-term safety and efficacy of clinical outcomes of aortic valve replacement using the "TiAra" prosthesis with or without concomitant procedures.
Main research objectives:
1. To analyze the short and mid-term (up to 3 years) outcome of aortic valve replacement using the "TiAra" prosthesis. 2. To study the hemodynamic characteristics of normally functioning "TiAra" prostheses in the aortic position, as well as the condition of the heart chambers in short and long-term period (up to 10 years) after the implantation. 3. To assess complications of the early and mid-term follow-up periods of aortic valve replacement using the "TiAra" prosthesis.
This study does not presuppose implementation of comparison groups.
Eligibility criteria

Age: 60-70 years old with a life expectancy of 3 years or more. Or a person younger than 60 with contraindications to taking anticoagulants, or with increased risk of their use, consciously choosing a biological prosthesis for valve replacement.
Isolated aortic valve disease.
Disqualifiers

The patient has any not related to the underlying cardiovascular system disease pathology that will lead to the death of the patient in less than 1 year.
The patient is currently participating in a study of a new drug or other medical devices.
