The aim – to present the first experience in Ukraine of using the NVT Allegra device for the procedure of transcatheter implantation of the aortic valve prosthesis to patients with high surgical risk with severe aortic stenosis. Materials and methods. The presented clinical cases included two patients of age 90 and 80 years with severe aortic stenosis, mean transaortic blood flow gradients of 32 and 76 mm Hg and aortic valve areas of 0.4 and 0.6 cm2, respectively. Both patients were recognized as high surgical risk patients. Results and discussion. Both patients underwent transcatheter implantation of the aortic valve prosthesis through transfemoral access. After implantation, the average gradients of the transaortic blood flow were 13 and 8 mm Hg respectively. Residual paravalvular insufficiency was mild in both cases. Second patient was implanted permanent pacemaker due to persistent complete AV block. Conclusions. The NVT Allegra system for transcatheter implantation of the aortic valve prosthesis is a third generation device that enables successful and safe intervention of the aortic valve.

Aim To improve quality of treatment for senile patients with pronounced aortic stenosis (AS).Material and methods Aortic valve stenosis (AS) is the most common valve pathology in cardiosurgical patients. Surgical correction of aortic valve (AV) stenosis accounts for 10 to 22 % of open-heart operations. 125 patients with pronounced AS were treated in the N. N. Burdenko Main Military Clinical Hospital between 2010 and 2017. This study was based on the implementation of new, minimally invasive methods in our clinic in 2013: balloon aortic valvuloplasty (BAVP) of the aortic valve and transcatheter aortic valve prosthesis (TCAVP).Results In the group of patients receiving the drug therapy alone, the in-hospital mortality was 2 %. At the time of maximum follow-up duration (3 years), the survival rate was 50.5 %. In the group of patients who underwent the AV replacement with extracorporeal circulation, the 3 year postoperative mortality was 16.6 %. There was no 3 year mortality in the group of patients who underwent TCAVP. The short-term beneficial effect of BAVP was confirmed.Conclusion An algorithm was developed for medical care of patients older than 75 with pronounced AS; the place of BAVP in the step-by-step management of these patients was determined. Using the developed approach in the management of these patients provided a 32 % (p<0.05) increase in the number of cases of radical surgical care.

We are presenting a case report of failed valve-in-valve treatment of severe aortic stenosis. A control ultrasonography after TAVI implantation revealed a severe aortic regurgitation of the graft which was subsequently unresolved with postimplantation dilatation. Second TAVI was implanted with cranial dislocation to the aortic root. Patient underwent a CT examination to clarify the TAVI in TAVI position. Patient underwent a surgical resection of TAVI with implantation of biological aortic valve prosthesis. In situations where TAVI treatment fails or is complicated beyond the possibility of endovascular repair, surgical intervention despite its higher risks is the preferred choice.

<p>Calcific aortic stenosis is an aortic valve disease of atherosclerotic origin occurring in 2-4 % of persons older than 65 years, for whom open surgery is contraindicated. Models of self-expanding aortic valves available today have a number of significant drawbacks. The authors have developed a prototype of a new aortic valve and present its first successful implantation in the experiment.</p><p>Received 17 October 2016.
