This registry is designed to monitor the real world clinical performance and safety of the V8 device used to perform balloon aortic valvuloplasty (BAV). Additional analyses or calculations may be obtained from the imaging or evaluations already performed per the sites' standard of care

Condition Intervention
Aortic Valve Stenosis Device: V8 Balloon Aortic Valvuloplasty (BAV) Catheter

Study Type: Observational [Patient Registry]
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Target Follow-Up Duration: 6 Months
Official Title: Transluminal Aortic Balloon Valvuloplasty Registry (TAB-R)

Primary Outcome Measures:
  • Efficacy Endpoint: V8 Device Performance [ Time Frame: Intra-procedure ]
    Successful balloon fixation: proximal and distal balloon segments are securely fixed on either side of the aortic valve annulus following inflation.

  • Safety Endpoint: Serious Adverse Events (SAE) [ Time Frame: Intra-procedure until discharge or 72 hours post-procedure, whichever comes first. (Typical discharge is expected to be within 72 hours.) ]
    The composite of SAEs as defined by the Valve Academic Research Consortium (VARC).

Secondary Outcome Measures:
  • Efficacy Endpoint: Intra-Procedure Hemodynamic Changes [ Time Frame: Intra-procedure ]
    Absolute and percent change in mean aortic valve (AV) gradient and aortic valve area (AVA).

  • Efficacy Endpoint: Post-Procedure Hemodynamic Changes [ Time Frame: Within 72 hours of procedure or discharge, whichever is first. (Typical discharge is expected to be within 72 hours.) ]
    Absolute and percent change in mean aortic valve (AV) gradient and aortic valve area (AVA).

  • Safety Endpoint: Aortic Valve (AV) Block at Discharge [ Time Frame: At discharge, which is expected to be within 72 hours procedure. ]
  • Safety Endpoint: Aortic Valve (AV) Block at 6-Month Follow-up [ Time Frame: 6-Month Follow-up ]

Primary Completion Date: December 2015 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: V8 Balloon Aortic Valvuloplasty (BAV) Catheter

    The V8 device can be used for BAV as follows:

    • as stand-alone intervention
    • as a bridge to transcatheter aortic valve replacement (TAVR)
    • as a bridge to surgical aortic valve replacement (SAVR)
    • as an intraprocedural predilatation prior to TAVR
Detailed Description:

The study is an open-label observational study involving a minimum of 10 centers. A minimum of 100 patients, including a minimum of 30 stand-alone balloon aortic valvuloplasty (BAV) treatment patients, will be enrolled. Enrollment will continue until all 3 of these conditions are met.

BAV-only patients will be followed through a 6-month post-treatment telephone follow up. Patients treated with the V8 device for BAV as a bridge to transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR) or as an intraprocedural predilatation prior to TAVR, will exit the study at the time of the TAVR or SAVR implant or at 6 months post-BAV treatment, whichever comes first.


Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Primary care clinic - Patients at each enrolling clinic who are to be treated with the InterValve V8 device for balloon aortic valvuloplasty (BAV) are eligible for enrollment.

Inclusion Criteria:

  • Symptomatic severe aortic stenosis (AS) patients who are not suitable candidates for aortic valve replacement surgery at the time of BAV procedure.
  • Subject meets the Indication For Use.
  • Probable survival to hospital discharge.
  • Subject is competent, willing to comply with evaluations, understands risks, benefits and alternatives and has signed the Informed Consent Form. Alternatively, the legal guardian of the patient is able to give consent to participate.

Exclusion Criteria:

  • Patient has undergone previous AVR
  • Greater or equal to 3+ aortic insufficiency by echocardiogram obtained prior to planned BAV or intra-procedural predilation TAVR procedure
  • Non-valvular AS
  • Known congenital AV abnormality (e.g., bicuspid AV)
  • Cardiogenic shock, as defined by a consistent systolic blood pressure <80 mmHg off vasopressors or <90 mmHg on vasopressors.
  • Bacterial endocarditis ≤ 12 months prior to planned BAV procedure
  • Unable to take aspirin (acetyl salicylic acid, ASA) or thienopyridine
  • Any illness or condition which, in the Investigator's judgment, will compromise patient safety, or interfere with the interpretation of the treatment results
  • Echocardiographic evidence of intracardiac mass, thrombus or vegetation.
