Long-term result of mitral and aortic heart valve replacement with domestic ball prostheses 35 years after the operation (clinical observation with review of the literature)
The development of the first domestic heart valve prostheses based on the model created in the USA - Starr-Edwards-type prostheses - was the first, but very successful. At the beginning of the 60s of the 20th century, the prostheses AKCh and MKCh developed and introduced into clinical practice at the Kirovo-Chepetsk Chemical Plant with some improvements, despite the emergence of competitive disc and bivalve models, were produced by the industry until 1992. This type of artificial valve showed not only good hemodynamic characteristics, but also a very impressive durability (over 30 years) in both the mitral and aortic position. In the literature, along with reports by foreign colleagues on the duration of monitoring patients with Starr-Edwards prostheses, the experience of the long-term functioning of domestic prostheses is practically not presented. Therefore, this article presents the results of a long period of observation of a patient 62 years old, who performed prosthetics of the mitral and aortic valves 35 years ago with prostheses AKCh and MKCh 35 years ago. The examination results demonstrate the normal function of implanted prostheses and the absence of signs of their structural dysfunction and good indicators of quality of life.
