<p>We report the successful endovascular correction of the migration of a transcatheter aortic valve prosthesis in the left ventricle outflow tract (LVOT). A 72-old man was underwent transcatheter aortic valve implantation (TAVI) at Almazov National Medical Research Centre for severe aortic stenosis. During the procedure, the self-expanding prosthesis dislocated 10–12 mm into the LVOT. The frame was optimised with the use of a balloon catheter, and aortic regurgitation I-II degree was achieved. However, on day 17 of hospitalisation, acute heart failure with episodes of asystole occurred as a result of severe paravalvular regurgitation; cardiopulmonary resuscitation was necessary. The prosthesis malpositioning was corrected by traction with endovascular snare devices. The patient was stable during the postprocedural period and discharged on day 31. Dislocation of self-expanding prostheses into the LVOT is a complication specific to TAVI that may quickly aggravate a patient’s condition; therefore, correction of valve malpositioning should be performed as soon as possible. The case reported here in an illustration of successful endovascular correction of dislocation performed with the snare traction technique. This bail-out approach can be used by interventional cardiologists in similar situations.</p><p>Received 27 May 2021. Revised 29 July 2021.

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.

Valve Implantation

<p><strong>Background.</strong> The obvious expansion of mini-invasive technologies is looming large in surgical treatment of heart diseases. Hundreds of thousands of transcatheter aortic valve replacement procedures have been performed in the world today. The improvement in quality and the increase in life expectancy in cohorts of patients who until recently have been considered inoperable are now routinely achievable. A significant limitation of this method for Russian clinics is the absence of domestic transcatheter implantable prosthetic heart valves on the market. During the last five years, such devices have been developed at “MedEng” (Penza, Russia) scientific and production enterprise. We present the first Russian transcatheter aortic valve prosthesis, its leaflets made of polytetrafluoroethylene, components of the delivery system and implantation, as well as the hospital outcomes of clinical trials. <br /><strong>Aim.</strong> To evaluate the clinical and hemodynamic results of transcatheter aortic valve implantation using a “MedLab-KT” prosthesis during hospital stay.<br />Methods. A prospective study included 54 patients who underwent transcatheter repair of the aortic valve using a “MedLab-KT” prosthesis. To evaluate the frequency of complications, myocardial infarction, strokes, bleeding, deaths during hospital stay and gradient indices on the prosthesis, postoperative ultrasound examination data were obtained and analyzed. <br /><strong>Results.</strong> The results are comparable with those achieved by using the foreign models known from literature. <br /><strong>Conclusion.</strong> The clinical and hemodynamic results of using the “MedLab-KT” aortic valve prosthesis can be considered as satisfactory.<br /><strong>Keywords:</strong> polytetrafluoroethylene; transcatheter aortic valve implantation<br /><strong>Funding:</strong> The study had no sponsorship.<br /><strong>Conflict of interest:</strong> The authors declare no conflict of interest.<br /><strong>Authors’ contribution</strong><br />Conception and study design: V.V.

<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.
