The aim – to systematize information on key features of echocardiographic evaluation of transcatheter aortic valve implantation (TAVI) procedure stages and their effectiveness in cardiac surgery, in patients with severe aortic valve stenosis.Materials and methods. We initiated a single-center clinical study to evaluate the XPand device and initial analysis of the primary results was performed. Patients met the inclusion criteria underwent a full range of examinations and TAVI procedures using the XPand device. The key parameters for echocardiographic examination in TAVI, which influence the formation of further procedure strategy, have been determined for the cardiac surgeon.Results and discussion. Based on the determined echocardiographic parameters, we obtained the primary outcomes of TAVI XPand in patients (n=7), the result of implantation was good. Minimal paravalvular insufficiency absence was found in 71.5 % of patients and minimal insufficiency in 14,5 %. In one patient to moderate insufficiency was observed. There was a statistically significant improvement in the ejection fraction (p<0.05) and a decrease in the mean gradient at the aortic valve (p<0.01).Conclusions. Echocardiographic parameters at all TAVI stages in patients over 75 years allow to control the implementation of the procedure and to improve the immediate post procedural outcome. The first experience of using the novel device for transcatheter implantation of the XPand aortic valve prosthesis confirms its effectiveness and safety in elderly patients with severe aortic stenosis.

  Background. Recent developments in the field of transcatheter aortic valve implantation (TAVI) have led to arised interest for the optimization of this procedure and related devices for patients with severe aortic valve stenosis. This is the first study to examine novel XPand device, jointly developed by German, French and Ukrainian scientists. This study aims to contribute to this growing area of research by exploring efficacy and safety in patients with severe aortic stenosis. Objective. To evaluate the procedure effectiveness and long-term outcomes for XPand device implantation in patients with severe aortic valve stenosis. Materials and methods. We initiated a single-center clinical trial to evaluate the XPand device and already perform an initial analysis of the primary outcomes. After patients fitted the inclusion criteria full examination they underwent TAVI procedure using the XPand system. Postoperative result evaluation was performed according to the established protocol. Outcomes. Primary good results for TAVI XPand were obtained in all patients (n = 7). The average length of stay in the hospital after the procedure was 20 ± 1.25 days. The postoperative period was unremarkable. In 71.5% of patients the minimal paravalvular insufficiency or insufficiency absence were obtained after the final aortography. Comments. The first experience of using modern device XPand for transcatheter implantation of the aortic valve prosthesis confirms its effectiveness and safety in patients with severe aortic stenosis.

Valve Implantation

Transcatheter aortic valve implantation (TAVI) and endovascular aortic repair (EVAR) are increasingly being used as therapeutic options for patients with severe aortic stenosis who are ineligible for surgery and who have aortic aneurysm with suitable anatomical features. These procedures can be associated with severe complications, especially related to vascular access and the use of a large introducer sheath (from 18 to 24 French [Fr]). In this article we describe possible vascular complications emerging during TAVI and EVAR and their appropriate management, beginning with patient selection, the correct way to perform vessel puncture and the use of a vascular closure device, up to the recently proposed cross-over technique, which is thought to minimise the risk of dangerous consequences of vascular damage.

Abstract Background Increasing number of symptomatic patients with severe aortic stenosis is treated with transcatheter aortic valve implantation (TAVI). Stroke is one of the most serious complications of TAVI, and the majority of cerebral events in patients undergoing TAVI have an embolic origin. Case summary A 90-year-old female underwent trans-femoral TAVI for symptomatic severe aortic stenosis. Just before the implantation of the transcatheter heart valve (THV), transoesophageal echocardiography (TOE) showed a mobile, high-echoic mass attached to the THV, which gradually enlarged to 26 mm, then spontaneously detached from the THV and flowed up the ascending aorta, disappearing from the TOE field of. After the procedure, the patient presented with ischaemic stroke. The patient’s stroke was thought to have resulted from the embolism migrating to the distal cerebral arteries. Discussion The detailed images acquired with TOE during TAVI enabled the prompt identification of the unusual intracardiac mass.
