Study Arms (1)

Percutaneous Aortic Valve 18F System

EXPERIMENTAL

Evaluation of the Direct Flow Medical Percutaneous Aortic Valve 18F System for the Treatment of Patients with Severe Aortic Stenosis.

Device: Replacement of the Aortic Stenotic Valve

Interventions

Treatment for patients with Severe Aortic Stenosis.

Also known as: TAVR
Percutaneous Aortic Valve 18F System

Eligibility Criteria

Age70 Years+
Sexall
Healthy VolunteersNo
Age GroupsOlder Adult (65+)

You may qualify if:

  • Severe aortic valve stenosis determined by echocardiogram and Doppler, defined as: mean gradient \>40 mmHg or peak jet velocity \>4.0 m/s and an aortic valve area ≤0.8 cm2 or aortic valve area index ≤0.5 cm2/m2
  • Symptomatic aortic valve stenosis demonstrated by angina, congestive heart failure, NYHA Functional Class ≥ II, or syncope
  • Patient is an extreme risk candidate for open surgical aortic valve repair such that the site Investigators (interventional cardiologist and cardiothoracic surgeon) agree that medical factors preclude operation, based on the conclusion that the probability of death or serious morbidity exceeds the probability of meaningful improvement due to the patient's co-morbidities (such as, but not limited to, severe COPD, porcelain aorta, previous thorax irradiation) or logistic EuroSCORE ≥ 20
  • ≥ 70 years old
  • Patient has been informed of the nature of the study and has provided written informed consent
  • Patient and treating physician agree that the patient will return for all required post-procedure follow-up visits

You may not qualify if:

  • Candidates will be excluded from the study if any of the following criteria are present:
  • Patient is a surgical candidate for aortic valve replacement
  • Congenital bicuspid or unicuspid valve determined by echocardiography
  • Native valve annulus diameter is \<17mm or \>22mm determined by the screening CT scan
  • Extreme asymmetrical calcification of the native aortic valve determined by the screening CT scan
  • Native valvular or peripheral vascular anatomy is not appropriate for the DFM bioprosthesis and 18F delivery system
  • Left ventricular ejection fraction (LVEF) \<30% determined by resting echocardiogram
  • Evidence of an acute myocardial infarction (Refer to Definitions in Section 8) within 30 days prior to the study procedure
  • Any percutaneous coronary or peripheral interventional procedure performed within 30 days prior to the study procedure
  • Any planned surgical or percutaneous coronary or peripheral procedure to be performed during the study procedure or prior to 30 day follow-up visit
  • Need for emergency surgery for any reason
  • Untreated clinically significant ( \> 70% obstruction) coronary artery disease requiring revascularization
  • Prior aortic or mitral valve surgery
  • Pre-existing prosthetic heart valve in any position
  • Mitral insufficiency greater than moderate determined by resting echocardiography
  • +20 more criteria
