[Long-term results of mitral valve prosthetics depending on the prosthesis model (ball, disk)]
Abstract:
The authors conducted a comparative analysis of patients of 2 groups--with a MK4 model ball prosthesis and an folding disc prosthesis. It was found that the number of late-term (repeated) thromboembolic complications was significantly less in patients with a disc prosthesis (3.95 cases per 100 patient-years) and 4.28 cases among patients with a ball prostheses. No fatal outcomes associated with thromboembolism occurred among patients with a disc prosthesis, the lethality among those with a ball prosthesis was 27.5%. The advantages of a disc prosthesis in indices of physical activity and increased survival were also established.
