Summary

The purpose of this study is to establish the safety and feasibility of the Edwards SAPIEN 3 valve in subjects with mitral annular calcification (MAC) associated with mitral stenosis (MS) and/or mitral regurgitation who are at high-risk for mitral valve surgery or deemed inoperable due to the extent of calcification.

Description

Technical Success:

Alive, with

  • Successful access, delivery and retrieval of the device delivery system, and
  • Deployment and correct positioning (including repositioning/recapture if needed) of the single intended device, and
  • No need for additional unplanned or emergency surgery or re-intervention related to the device or access procedure

Device Success:

Alive and stroke free, with

  • Original intended device in place, and
  • 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/Operating Room(OR)), and
  • Intended performance of the device:
  • Structural performance: No migration, embolization, detachment, fracture, hemolysis, thrombosis (including reduced leaflet motion) or endocarditis, etc, and
  • Hemodynamic performance: Maintenance of relief of stenosis or insufficiency without producing the opposite (Stenosis = Mitral Valve Area (MVA) < 1.5cm2 and Mitral Valve (MV) gradient > 5mmHg, Insufficiency = Mitral Regurgitation (MR) >1+), and
  • Absence of para-device complications (e.g., Paravalvular Leak (PVL) > mild, need for a Permanent Pacemaker (PPM), erosion, Annular rupture or Aortic Valve (AV) Groove disruption, Left Ventricular Outflow Tract (LVOT) gradient increase > 10mmHg)

Procedural Success:

Device success, and

  • No device or procedure related Serious Adverse Events (SAEs) (Life threatening bleed; major vascular or cardiac structural complications requiring unplanned reintervention or surgery; stage 2 or 3 Acute Kidney Injury (includes new dialysis); Myocardial Infarction (MI) or need for percutaneous coronary intervention (PCI)/coronary artery bypass graft (CABG); severe heart failure (HF) or hypotension requiring intravenous (IV) inotrope, ultrafiltration or mechanical circulatory support; prolonged intubation ( > 48 hours)

6.2 Secondary objective(s)

Device Success (at 6 months and 1 year)

  • Subject success 1 year

Device Success:

Alive and stroke free, with

  • Original intended device in place, and
  • 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/Operating Room (OR)), and
  • Intended performance of the device:
  • Structural performance: No migration, embolization, detachment, fracture, hemolysis, thrombosis (including reduced leaflet motion) or endocarditis, etc, and
  • Hemodynamic performance: Maintenance of relief of stenosis or insufficiency without producing the opposite (Stenosis = MVA < 1.5cm2 and MV gradient > 5mmHg, Insufficiency = MR >1+), and
  • Absence of para-device complications (e.g., PVL > mild, need for a PPM, erosion, Annular rupture or AV Groove disruption, LVOT gradient increase > 10mmHg)

Eligibility

Yes No Not Sure

Inclusion Criteria

Is your age greater than or equal to 22 yrs?
Gender: Male or Female
Do you have Mitral Annular Calcification?
Do you have any of these conditions: Do you have Mitral Annular Calcification??
Do you have any of these conditions: Do you have Mitral Annular Calcification??
Subject has severe native mitral annular calcification associated with mitral stenosis and/or regurgitation. Qualifying echo must be within 60 days of the date of the procedure
Subject has a clinical indication for mitral valve replacement, as demonstrated by reported New York Heart Association (NYHA) Functional Class II or greater
The subject is at least 22 years old
The Heart Team agrees that the subject is high risk or inoperable for surgical mitral valve repair or replacement (MVR), based on a conclusion that the probability of death or serious, irreversible morbidity exceeds the probability of meaningful improvement. The following concomitant procedures, are allowed: MAZE, Tricuspid Valve Procedures (TVP), and Atrial Fibrillation (AF) ablation, coronary artery bypass grafting and septal myectomy
The study subject has been informed of the nature of the study, agrees to its provisions and has provided written informed consent as approved by the Institutional Review Board (IRB) of the respective clinical site
The study subject agrees to comply with all required post-procedure follow-up visits

Exclusion Criteria

Evidence of an acute myocardial infarction (MI) 30 days before the intended treatment [defined as: Q wave MI, or non-Q wave MI with total CK elevation of CK-MB twice normal in the presence of MB elevation and/or troponin level elevation (WHO definition)]
Any therapeutic invasive cardiac procedure resulting in a permanent implant that is performed within 30 days of the index procedure (unless part of planned strategy for treatment of concomitant coronary artery disease)
Leukopenia (white blood cell count < 2000 cell/mL), acute anemia (hemoglobin < 8 g/dL), or thrombocytopenia (platelet count < 50,000 cell/mL)
Hemodynamic or respiratory instability requiring vasoactive medications, mechanical ventilation at time of procedure
Need for emergency surgery for any reason
Severe left ventricular dysfunction with Left Ventricular Ejection Fraction (LVEF) < 30%
Severe right ventricular dysfunction
Pregnancy, lactation, or planning to become pregnant
Echocardiographic evidence of left ventricular mass, thrombus, or concerns of active infective endocarditis
Active upper gastrointestinal (GI) bleeding within 3 months prior to procedure without treatment or 30 days prior to procedure with definitive treatment
A known contraindication or hypersensitivity to all anticoagulation regimens, or inability to be maintained on oral anticoagulant following the study procedure
End stage renal disease requiring dialysis
Clinically (by neurologist) or neuroimaging confirmed stroke or transient ischemic attack (TIA) within 30 days of the procedure
Estimated life expectancy < 12 months
Clear my responses
