[The first 200 transcatheter aortic valve implantations in the Gottsegen Gyorgy Institute of Cardiology, Hungary]. / Az elso 200 transzkatéteres aortabillentyu-implantáció a Gottsegen György Országos Kardiológiai Intézetben.

ABSTRACT

INTRODUCTION: Transcatheter aortic valve implantation is a therapeutic alternative for contraindicated and high surgical risk patients with severe symptomatic aortic stenosis. This intervention is part of daily routine in the Institute of the authors. AIM: In the present work the results of the first 200 patients are discussed. METHOD: Until January, 2016, 200 patients (female 55%, mean age 79.9 years, average EuroSCORE 19.3%, left ventricular ejection fraction 54%, peak gradient 81.2 mmHg, mean aortic gradient 50.9 mmHg) underwent transcatheter aortic valve implantation. RESULTS: The procedure was performed with 99% success rate. Complications were evaluated according to VARC 2 definitions. Mortality was 5% at one month and 17.4% at one year. Cardiac mortality was 13.6 at one year. Cerebrovascular complications were 5% within one year, and 95% of patients were in NYHA I or II functional classes at one year. CONCLUSION: These findings are consistent with worldwide results. Orv. Hetil., 2016, 157(45), 1786-1792.
