Study summary

Prospective non interventional, observational registry of 150 patients undergoing TAVI with Evolut platform for bicuspid aortic stenosis.

Read the detailed description

Study Design Study Design: prospective non-interventional multicenter registry Screening: MSCT submitted to core lab \& sizing strategy pre-declared (annular sizing, supra-annular sizing, mix of both methods) Follow up: MSCT and TTE to cooper lab

Inclusion Criteria 1. Age ≥18 years. 2. NYHA≥2 and/or syncope and/or angina. 3. Patient judged by the Heart Team as indicated for TAVI. 4. Anatomical suitability for transfemoral-TAVI with Evolut Pro or Evolut R XL, based on MSCT assessment.

5. Estimated life-expectancy>1 year.

Exclusion Criteria 1. Age \<18 years 2. Asymptomatic patients 3. Estimated life expectancy\<1 year 4. Pure aortic regurgitation. 5. LVEF\<20% 6. No baseline MSCT evaluation. 7. Unsuitable aortic root anatomy for Evolut Pro or XL. 8. Unsuitable peripheral vasculature for transfemoral Evolut Pro or XL. Primary Endpoint Valve performane Secondary endpoints 30 day and 1 year mortality Patient-prosthesis mismatch Ellipticity index at 30 days Follow-up 30 days: physical examination, ECG, TTE /MSCT upon operators' judgement

1 year: physical examination, ECG, TTE.

Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 18, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
