Study summary

The study protocol is a randomized trial of standard of care therapies for severe aortic stenosis (AS) in patients with a bicuspid aortic valve (BAV). Namely, the therapies to which patients will be randomized will be transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR), in patients deemed clinically suitable for both following heart team review.

The purpose of this study is to compare the safety and efficacy of Transcatheter Aortic Valve Replacement (TAVR) versus Surgical Aortic Valve Replacement (SAVR) for treating patients with severe aortic stenosis (AS) who have a congenital bicuspid aortic valve (BAV) anatomy. Patients with BAV anatomy have been under-represented in previous trials and this study might provide important information to help guide future treatment options.

The study patients will be followed with standard of care procedures for 10 years.

What researchers measure

Primary outcomes

  1. 1 year hierarchical composite outcome of death, disabling stroke, non-disabling stroke, valve reintervention, rehospitalization, unfavorable KCCQ (VARC 3)

    The primary endpoint will be analyzed by the Win ratio method14. That is, every patient in the TAVR group will be compared with every patient in the SAVR group to determine which pair has won. A win higher up in the hierarchy takes priority, so KCCQ gets used only for those pairs that were tied on the first 5 event components. Then KCCQ win is declared if the time-averaged change in KCCQ differs by 5 points or more. The win ratio= total wins on TAVR divided by total wins on SAVR, for which a 95% CI and p value is calculated.

    Time frame: 1 year

Secondary outcomes

  1. Technical success at time of exit from OR/cath lab

    defined as meeting of the following: * Alive * Successful access, delivery and retrieval of the device delivery system * Deployment and correct positioning (including repositioning /recapture if needed) of the single intended valve * No additional unplanned or emergency surgery or re-intervention prior to leaving OR/Cath lab related to the device or access procedure (includes need for return to bypass post initial wean

    Time frame: exit from procedure (OR or cath lab)

  2. Device success

    Defined as meeting all of the following: * Alive and stroke-free * Original intended device in place * No additional surgical or interventional procedures related to access or the device since completion of the original procedure (i.e., exit from the cath lab/OR) * Intended performance of the device: 1. Structural performance: No migration, embolization, detachment, fracture, or thrombosis 2. Hemodynamic performance: Mean gradient \< 20mmHg, AVA \>1cm2, jet velocity \< 3.0 m/s 3. Absence of the following para-device complications (PVL \> mild, erosion, hemolysis, or endocarditis)

    Time frame: 30 days

  3. Procedural success

    Defined as meeting all of the following: 1. Life-threatening bleed (BARC 3b or greater) 2. Major vascular or cardiac structural complications requiring unplanned reintervention or surgery 3. Stage 2 or 3 AKI (includes new dialysis) 4. MI or need for PCI/CABG 5. Severe heart failure or hypotension requiring IV inotrope \>12 hours, ultrafiltration or mechanical circulatory support 6. Prolonged intubation \> 48 hours 7. Need for a permanent pacemaker implant or continuous, new onset atrial fibrillation

    Time frame: 30 Days

  4. Patient success

    Defined as meeting all of the following: * Device success * No re-hospitalizations or re-interventions for the underlying condition (e.g., Aortic stenosis and Heart Failure) * Return to prior living arrangement (or equivalent) * Improvement in symptoms defined as increase in NYHA Class \> 1 compared to Baseline * Improvement in functional status defined as 6MWT \> 25 m compared to Baseline * Improvement in quality-of-life defined as KCCQ score \> 10 compared to Baseline

    Time frame: 1 year
