Is this trial a fit for you?

Likely a good fit

Adults (≥18 years) with severe native aortic regurgitation who are deemed high or prohibitive surgical risk by the local heart team and who have anatomy suitable for the JenaValve Trilogy per the instructions for use.

Probably not a fit

Patients with known hypersensitivity to nitinol or device materials, active bacterial endocarditis or other active infections, inability to tolerate required anticoagulation/antiplatelet therapy or contrast, or anatomy incompatible with the device are unlikely to benefit from enrollment.

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

What this trial studies

ARTEMIS is a single-arm, retrospective/prospective post-market data collection that follows up to 75 patients treated with the JenaValve Trilogy system for severe native aortic regurgitation. The study captures real-world safety and effectiveness outcomes after TAVR using the Trilogy valve, with planned follow-up to one year (an extension to five years may be added). Enrollment is at IRCCS Policlinico San Donato and includes patients selected by the local heart team who meet the device instructions for use. Data collected will include procedural details, complications, and clinical outcomes reported under routine clinical care.

Why it matters

Potential benefit: If successful, this could offer a less invasive valve replacement option for patients with severe aortic regurgitation who are poor candidates for surgical replacement.

How similar studies have gone: Previous single-arm registries and small series of transcatheter valves for aortic regurgitation, including prior JenaValve reports, have shown feasibility and reasonable outcomes in selected patients but randomized comparative evidence remains limited.

Who can join: the full rules

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Considered at high or prohibitive risk for surgical aortic valve replacement by the Heart Team

  * 18 years of age or older
  * Suitable anatomy according to the IFU
  * Absence of significant disease of the ascending aorta, including ascending aortic aneurysm (defined as maximal luminal diameter of 50mm or greater) or atheroma (especially if thick \[\>5mm\], protruding or ulcerated)

Exclusion Criteria:

The JenaValve Trilogy Heart Valve System is contraindicated for use in patients who have known hypersensitivity or contraindication to Nitinol (titanium and/or nickel), an anti-coagulation/anti-platelet regimen or contrast medium that cannot be managed with premedication, or who have active bacterial endocarditis or other active infections.

The JenaValve Trilogy Heart Valve System is contraindicated in those patients whose anatomy does not accommodate the System due to anatomical considerations outlined in the inclusion criteria.
