Use of DurAVR™ THV System in Subjects With Severe Aortic Stenosis: Early Feasibility Study

To evaluate the safety and feasibility of DurAVR™ THV System in the treatment of subjects with symptomatic severe native aortic stenosis.

SMall Annuli Randomized To Evolut™ or SAPIEN™ Trial

The purpose of this trial is to generate clinical evidence on valve safety and performance of self-expanding (SE) versus balloon-expandable (BE) transcatheter aortic valve replacement (TAVR) in subjects with a small aortic annulus and symptomatic severe native aortic stenosis. Additionally, a stress echocardiography sub-study will be conducted as part of the SMART Trial at select sites. The purpose of the sub-study is to evaluate performance of SE versus BE TAVR in subjects with a small aortic annulus and symptomatic severe native aortic stenosis after undergoing exercise stress echocardiographic testing.

Pivotal Study of the Vienna Transcatheter Self Expandable Aortic Valve SE System

This is a prospective, single arm, multicenter study in an cohort of up to 267 patients (up to 100 Roll-ins and 167 patients implanted per protocol) symptomatic patients with severe aortic stenosis who will be followed up for up to 5 years.

Structured Shared Decision Making for Patients Undergoing SAVR or TAVR

Transcatheter aortic valve replacement (TAVR) is a well-established alternative to surgical aortic valve replacement (SAVR) for the treatment of patients with severe aortic stenosis regardless of surgical risk. While TAVR and SAVR share some of the benefits and risks, they importantly differ with regards to invasiveness, time to recovery, hemodynamics, as well as options for re-intervention and possibly valve durability. An early benefit of TAVR may be offset by late risks. Therefore, current guidelines of the European Society of Cardiology recommend an integration of patient values and preferences for the selection of the treatment modality. The objective of the TOGETHER trial is to investigate the efficacy of a structured shared decision making approach (SDM) to improve patient-centered outcomes for the choice between SAVR and TAVR. TOGETHER is an investigator-initiated, randomized, open-label, single-center clinical trial. A total of 140 patients referred for treatment of symptomatic severe aortic stenosis and deemed to undergo TAVR or SAVR according to heart team decision will be randomized in a 1:1 ratio to structured SDM or usual care.

DurAVR™ THV EU-EFS

A prospective, non-randomized, single-arm, multi-center study designed to evaluate the safety and feasibility of DurAVR™ THV System in the treatment of subjects with symptomatic severe native aortic stenosis or failed surgical aortic bioprosthetic valves.

Transcatheter Aortic Valve Replacement Single Center Registry in Chinese Population

The purpose of this study is to evaluate the safety and effectiveness of transcatheter aortic valve replacement in Chinese population.
