Transcatheter aortic valve implantation – single center experience

Introduction: Transcatheter aortic valve implantation (TAVI) is alternative treatment for high risk patients with severe, symptomatic aortic stenosis. The TAVI procedures are associated with good immediate and long-term outcomes.

Aim: To determine the success, complications, and survival of patients after TAVI during hospitalization in single center.

Material and methods: A cohort of 22 patients (age 79.7 years, logistic Euroscore 23.2) with severe aortic stenosis underwent TAVI procedures. The approach was femoral in 16 patients and transapical in 6 patients.

Results: Procedural success was achieved in 21 patients (95%). AVA and Pmax before and after the procedure were respectively: 0.65 ±0.1 cm², 99.1 ±27.1 mm Hg and 2.5 ±0.4 cm², 15.8 ±4.4 mm Hg. Hospital mortality was 9% (2/22). One patient (with biscupid valve) died on 27 day after cardiosurgery due to aortic dissection resulting from shifting CoreValve to ascending aorta. One patient died after tamponade and multi-organ failure 4 days after procedure. During hospitalization there was no severe aortic regurgitations, strokes, myocardial infarctions and contrast induced nephropathies (excluding patients who died, nephropathy as a component of multi-organ failure).

Conclusions: Transcatheter aortic valve implantation procedures in high risk patients not qualified for surgery is efficacious method of treatment for severe, symptomatical aortic stenosis.
