Abstract		Degenerativna kalcinirana stenoza aortne zaklopke (DKAS) je najpogostejša okvara aortne zaklopke v zahodnem svetu. Gre za kronično progresivno bolezen, katere prevalenca s starostjo hitro narašča. Patohistološki proces je zelo podoben aterosklerozi. Glede na površino aortnega ustja in razliko tlakov, ki nastane med levim prekatom in aorto, jo delimo na blago, zmerno in hudo. Glavni klinični simptomi so dispneja, sinkopa, bolečina v prsih, lahko pa pride tudi do motenj srčnega ritma. Tretjina bolnikov s simptomatsko hudo aortno stenozo ni primerna za kirurško zamenjavo aortne zaklopke, ki je sicer zlati standard zdravljenja. Perkutana aortna balonska valvuloplastika (BAV) je poseg, pri katerem z napihnjenim balonom razširimo kalcinirano aortno zaklopko. Poseg opravimo pri bolnikih, ki imajo visoko tveganje za operativni poseg ali pri hemodinamsko nestabilnih bolnikih kot premostitev do kirurške zamenjave aortne zaklopke (AVR) ali perkutane zamenjave aortne zaklopke(TAVI). Pri velikem deležu bolnikov pride do izboljšanja simptomov, vendar pa je poseg povezan z visokim odstotkom zapletov in smrtnosti.Degenerative calcinated stenosis of aortic valve is the most common aortic valve failure in western world. We are dealing with progressive chronic disease with rising prevalence in older age. The pathohistological process is similar to atherosclerosis. The main classification criteria are based on the aortic valve surface area andt he gradient difference between left ventricule and aorta: mild, moderate and severe. Main clinical symptoms are dispnea, sincope, chest pain and arrhythmias. Around one third patients with symptomatic severe aorticvalve stenosis are not suitable for surgical treatment, which is the golden standard of treatment. Percutaneous aortic valve balloon valvuloplasty (BAV) is a procedure, where using a balloon the calcificated aortic valvule is dilatated. The procedure is performed in patients with high perioperative risk or hemodinamically stable patients as bridging to aortic valve replacement (AVR) or transcatheter aortic valve implantation (TAVI). Despite efficiency in many cases, the procedure is followed with high percentage of complications and mortality.
