Balloon expandable vs. self-expandable transcatheter aortic valve prosthesis short-term results of retrospective study

Transcutaneous aortic valve implantation has been established as an effective method for the treatment of highgrade stenosis in non-operative, high-risk conventional surgery patients. According to developed technologies, prostheses are divided into balloon-expandable (balloon-expandable valves, BEV) and self-expanding (self-expanding SEV). The two types devices have different models implantation, stratum architecture, cusps characteristics, leading hemodynamics, frequency use performance normal prosthesis function. research aims monitor short-term results, up 1 month after discharge, terms mortality, manifestation heart failure, (para) prosthetic regurgitation, a pacemaker, vascular complications. Materials methods: article presents retrospective follow-up total 230 cardiac patients with high-grade treated cardiology clinic at UMHAT St. Ekaterina Sofia until 2020, groups depending on implanted type prosthesis. Conclusions: results obtained based our experience prove safety new prostheses. When choosing between BEV SEV, best clinical outcome requires good knowledge strengths weaknesses using medical personalized approach consistent anatomical characteristics patient.
