A bal pitvari fülcse perkután zárása nonvalvularis pitvarfibrillációban – nemzetközi és hazai tapasztalatok = Percutaneous left atrial appendage closure in non-valvular atrial fibrillation – review of literature and own experiences

2010 
Nonvalvularis pitvarfibrillacioban szenvedő betegek eseten az oralis antikoagulans kezeles stroke-prevencios hatekonysaga egyertelműen bizonyitott. Ezen betegek nem elhanyagolhato hanyada szamara azonban a magas thromboembolias kockazat ellenere sem kivitelezhető a hosszu tavu antikoagulans kezeles. Elsősorban ennek koszonhető, hogy napjainkban egyre inkabb az alternativ kezelesi strategiak kerulnek az erdeklődes homlokterebe. Nonvalvularis pitvarfibrillacioban a thrombuskepződes leggyakoribb helye a bal pitvari fulcse. Az europai piacon jelenleg ket perkutan fulcsezaro eszkoz erhető el: Watchman LAA System (Atritech Inc.) es az Amplatzer Cardiac Plug (AGA Medical Corporation). Bar a kozelmultban zarult klinikai vizsgalatok (PLAATO, PROTECT AF) szerint a perkutan bal pitvari fulcsezaras elfogadhato biztonsagossagi profil mellett csokkenti a hosszu tavu stroke-kockazatot, a rendelkezesunkre allo adatok meg korlatozottak. Jelenleg ezek a beavatkozasok a nonvalvularis pitvarfibrillacioban szenvedő magas stroke-kockazatu betegek azon csoportja szamara jelenthetnek elfogadhato megoldast, akiknel az oralis antikoagulans terapia nem alkalmazhato vagy az optimalis hatekonysag nem elerhető. A Gottsegen Gyorgy Orszagos Kardiologiai Intezetben 2010. januar 28-an, Magyarorszagon elsőkent, harom, nonvalvularis pitvarfibrillacioban szenvedő betegunknel vegeztunk sikeres perkutan bal pitvari fulcsezarast. | In patients with non-valvular atrial fibrillation, efficacy of stroke prevention with oral anticoagulant therapy has been proved. Despite their high risk for thromboembolic events, there are substantial numbers of patients who are not candidates for long-term oral anticoagulant therapy, therefore the interest in alternative treatment strategies are in focus these days. The most common place within the heart for thrombus formation in patients with non-valvular atrial fibrillation is the left atrial appendage. Two devices specifically designed for percutaneous left atrial appendage closure are currently available in Europe: the WATCHMAN LAA system (Atritech, Inc) and the AMPLATZER Cardiac Plug (AGA Medical Corporation). Although present trial results (PLAATO, PROTECT AF) suggest that LAA closure may be performed at acceptable safety and it may reduce the long-term stroke risk, available data are still very limited. At present these procedures may be an acceptable alternative in selected high-risk patients with non-valvular atrial fibrillation who are not or suboptimal candidates for oral anticoagulant therapy. On 28. January, 2010 we performed the first three successful percutaneous left atrial appendage closure procedures in Gottsegen Gyorgy Hungarian Institute of Cardiology in Hungary.
