To determine the possibilities of multislice computed tomography (MSCT) in planning of transcatheter aortic valve implantation (TAVI).
To define the access path of TAVI,
size and type of aortic valve prosthesis.
Methods and Materials
Sixty five patients with severe aortic stenosis and multiple comorbidities at median age of 77 years were included.
An average gradient of systolic pressure on the aortic valve before the operation was 76,3±22,5 mm Hg.
All patients were in III-IV functional class by NYHA.
The risk of conventional open repair was >20% by EuroSCORE and > 10% by STS.
MSCT angiography of coronary and femoral arteries were performed to all patients.
Measurement of aortic valve annulus,
coronary arteries ostiums,...
The possibility of TAVI procedure was estimated due to the results of MSCT measurements.
Either Edwards or CoreValve bioprostheses were implanted,
the decision being made with regard to various aortic valve and vascular anatomy due to MSCT.
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.
Surgical treatment for aortic valve pathology is an urgent and important problem of modern medicine.
The prevalence of valve disease is great and remains steadily high in the population.
Due to a large number of patients who cannot undergo open AV surgery,
alternative hybrid treatments are recently being actively improved.
Multislice spiral computed tomography is mandatory prior to transcatheter AV replacement as the examination results determine if a hybrid treatment can be performed and the...
