SOME INNOVATIVE TECHNOLOGIES FOR THE CORRECTION OF VALVULAR HEART DISEASES. REVIEW
Valve defects or congenital/acquired heart defects are damage to the valve and/or subvalvular structures, which leads to impaired hemodynamics and the development of heart failure. Asymptomatic valvular heart disease is present in 2.5% of the population; with age, this figure rises to 13%. In the absence of permanent treatment, lesions of the heart valves significantly reduce the quality and duration of life. The European Society of Cardiology (ESC) and the American Heart Association (AHA) regularly review the effectiveness of new surgical treatments and reflect their findings in international guidelines. Today, minimally invasive surgery is the most effective and safe way to treat patients with valvular heart disease. The article presents two new methods for the treatment of valvular heart disease. Transapical mitral valve repair on a beating heart with neochord implantation (TOP-MINI) is a new MVP option that has been approved for patients with severe mitral regurgitation due to prolapse of the leaflet (s) or chord (grades 2-4). The new procedure with the NeoChord DS1000 device results in a significant reduction in mitral regurgitation and in reverse remodeling of the left ventricle and left atrium after 6 months of follow-up. Also reviewed is Minimally Invasive Aortic Valve Replacement (MAVR), which has been shown to be beneficial in improving patient satisfaction by minimizing pain and earlier recovery. Sutureless valves are preferred over traditional aortic valve replacement (AVR) due to the reduced operation time and the need for blood transfusion. The Perceval valve (Sorin, Sallugia, Italy) is a self-expanding bovine pericardial prosthesis placed in a nitinol stent designed to facilitate aortic valve implantation. A systematic review and meta-analysis demonstrated that the early clinical and hemodynamic characteristics of the Perceval valve are satisfactory and comparable to those of conventional AVRs. This literature review was carried out in accordance with the PRISM statement. The databases searched in this review included Pubmed, Web of Science, Scopus and Cochrane databases for systematic reviews.
