This study is testing whether getting a heart valve replacement without immediate access to heart surgery is as safe and effective as having it done where surgery is available for patients needing this treatment.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients with severe aortic stenosis who are either inoperable or at high surgical risk as determined by the Heart Team.

Probably not a fit

Patients unsuitable for transfemoral TAVI or those requiring emergent procedures may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The TRACS trial aims to compare the outcomes of transcatheter aortic valve implantation (TAVI) performed in centers without on-site cardiac surgery to those performed in centers with on-site surgery. This multicenter, randomized trial will involve experienced operators and will assess all-cause death, stroke, and rehospitalization for cardiovascular causes. Patients will be recruited based on a Heart Team's indication for TAVI, and their eligibility will be confirmed by a unanimous decision of the team. Participants will be randomized in a 2:1 ratio to receive TAVI in either setting.

Why it matters

Potential benefit: If successful, this study could provide a safe and effective option for patients with severe aortic stenosis who are at high surgical risk.

How similar studies have gone: Other studies have shown promising results with TAVI procedures, but this specific comparison of settings is novel.

* Indication to TAVI confirmed by the Study Heart Team

AND one of the following:

* Frailty/Reduced physical performance
* Cognitive impairment, dementia, or Parkinson's disease
* Severe liver disease/cirrhosis
* Hostile chest
* Internal mammalian artery or other critical conduit(s) crossing midline and/or adhering to the posterior table of the sternum
