Results
The possibility of TAVI procedure was estimated due to the results of MSCT measurements. In 34 cases TAVI was performed through transfemoral access,
in 18 patients - via transapical access,
and in 1 patient – direct transaortic approach was used.
10 patients were excluded due to specific anatomy of annulus and femoral arteries kinking.
Intraoperative mortality was 1.9%: 1 patient (women) died with symptoms of acute heart failure.
2 patient died within 7 days after TAVI from myocardial infarction and other 2 patients developed cardiogenic shock.
Total 30 days mortality rate was 9.8%.
Other patients had no major complications.
The average mean pressure gradient after Edwards Sapien and Medtronic CoreValve implantations were 10,9±3,5 and 14,3±5,4 mm Hg respectively (p>0.05).
The incidence of paravalvular leak of 2 degree had a tendency to be higher in CoreValve than in Edwards Sapien subgroup (15% vs.
3%).
In 5 patients after CoreValve implantation (25%) we observed the development of conduction disturbances that required permanent pacemaker.
