Aortic annulus angulation does not attenuate procedural success of transcatheter aortic valve replacement using a novel self-expanding bioprosthesis.

The objectives of the study were to evaluate the impact of aortic angulation (AA) on success of transcatheter aortic valve replacement (TAVR) with a new generation self-expandable prosthesis (Medtronic Evolut R®). Specific anatomical conditions, such as for example the presence of a horizontal aorta with elevated AA, have seemed to pose a significant challenge for the correct positioning and consequent functioning of self-expandable TAVR prostheses. We assessed 146 patients treated with Evolut R.

Trans-catheter aortic valve implantation with the direct flow medical prosthesis: Single center short-term clinical and echocardiographic outcomes.

Objectives: To analyze our single center experience with the Direct Flow Medical (DFM).

Background: The DFM has been recently introduced to the market and large real world experiences are lacking.

Methods: A total of 126 patients with severe aortic valve stenosis (AVS) were treated by the same team from March 2013 to May 2015.

Transcatheter aortic valve implantation with the direct flow medical prosthesis: Impact of native aortic valve calcification degree on outcomes.

Objectives: We present our single center experience with the direct flow medical (DFM) prosthesis addressing the impact of native aortic valve (AV) calcification degree on outcomes.

Background: The DFM® has been introduced for transcatheter aortic valve implantation (TAVI). The valve has a nonmetallic and inflatable support structure.

Transcatheter aortic valve implantation in obese patients: Overcoming technical challenges and maintaining adequate hemodynamic performance using new generation prostheses.

Background: Second-generation TAVI prostheses may enhance the procedure reducing operative time and complications rate, maintaining adequate valve hemodynamic performance. We present our results with 2 new generation trans-catheter aortic valve (TAVI) prostheses in obese patients.

Methods: A series of 172 patients underwent trans-femoral TAVI with new generation prostheses (Direct Flow Medical, DFM®, and LOTUS®).
