Background
Transcatheter aortic valve implantation (TAVI) has been recognized as a primary strategy in treatment of severe aortic stenosis (AS) in high-risk patients. Recently along with the progress of technology some data was obtained to elucidate safety and good clinical efficacy of TAVI in patients of intermediate surgical risk.
Material and methods
110 patients with a median age of 77 ± 6,4 (60-91) years were included. All patients had severe aortic stenosis with peak pressure gradient 87±6.6mmHg. Mean EuroSCORE was 8,9%. We have used both Edwards Sapien/Sapiens XT (ES) and Medtronic CoreValve bioprostheses (CV), the decision being made with regards to different aortic valve and vascular anatomy. In 79 cases implantation was performed through transfemoral access and in 22 cases – transapical access was used due to vascular abnormalities. In the rest 9 cases we used direct transaortic (6 patients) and transsubclavian approach (3 patients). General anesthesia was performed in 88%.
