About

The VITALYST Early Feasibility study (EFS) is designed to evaluate the feasibility and safety of the VITALYST System in subjects undergoing elective high-risk percutaneous coronary intervention (HR-PCI).

Full description

The VITALYST EFS is a prospective, open-label, single-arm, multicenter feasibility study of the VITALYST System.

The VITALYST System will be used to provide temporary circulatory support in patients undergoing non-emergent high risk percutaneous interventions (HR-PCI).

Inclusion criteria

  • Subject provides signed informed consent.
  • Subject is ≥ 18 years and < 90 years of age.
  • Subject is indicated for NON-emergent PCI of at least one de novo or restenotic lesion in a native coronary vessel or coronary artery bypass graft (CABG) and has left ventricular ejection fraction (LVEF) ≤ 50% with the following: Unprotected left main or Last remaining vessel or Three vessel disease (at least one ≥ 50% diameter stenosis based on center's visual assessment in all three major epicardial territories)
  • Heart team, which must include a cardiac surgeon, agrees that HR-PCI is appropriate.

Exclusion criteria

  • Subject has had STEMI within 72 hours with persistent elevation of cardiac enzymes.
  • Subject has had pre-procedure cardiac arrest requiring CPR within 24 hours of enrollment.
  • Subject has systolic blood pressure < 90 mmHg with evidence of end organ hypoperfusion (e.g., cool extremities or urine < 30 mL/hour).
  • Subject has had need for inotropes/vasopressors or mechanical circulatory support (including intra-aortic balloon pump) in the previous 24 hours to maintain a systolic blood pressure ≥ 90 mmHg.
  • Subject has left ventricular mural thrombus.
  • Subject has a prosthetic aortic valve.
  • Subject has pericarditis or constrictive heart disease (constrictive pericarditis or restrictive cardiomyopathy).
  • Subject has moderate or greater aortic valve stenosis or moderate or greater aortic valve insufficiency (by echocardiographic assessment, graded as > 2+).
  • Subject has abnormalities of the aorta that preclude safe delivery of the device, including severe calcification, tortuosity, aneurysm, or prior surgery.
  • Subject has PVD preventing passage of the device (e.g., calcification, small caliber) or tortuosity that would preclude safe placement of the introducer sheath as per the IFU.
  • Subject is not on dialysis and has creatinine > 4 mg/dL.
  • Subject has a history of liver dysfunction (Childs Class C) with elevation of liver enzymes and bilirubin > 3× ULN or INR ≥ 2.
  • Subject has had a recent (within 30 days) stroke or TIA.
  • Subject has known hypersensitivity to intravenous contrast agents that cannot be adequately pre-medicated or has known hypersensitivity to heparin, aspirin, ADP receptor inhibitors or nitinol.
  • Subject has current or a history of heparin induced thrombocytopenia.
  • Subject has uncorrected abnormal coagulation or platelet count ≤ 75,000/mm³ or INR ≥ 2.0.
  • Subject has significant right heart failure based on any one of the following criteria: RVSWI < 0.30 mmHg·L/m² or PVR > 3.6 Woods units or Pulmonary artery pulsatility index < 1.85
  • Subject requires non-elective mechanical ventilation.
  • Subject has an atrial or ventricular septal defect (including post-infarct VSD).
  • Subject has left ventricular rupture.
  • Subject has cardiac tamponade.
  • Subject has severe pulmonary disease (FEV1 < 1L).
  • Subject has sustained or non-sustained ventricular tachycardia.
  • Subject is breast feeding or is pregnant.
  • Subject has infection of the proposed procedural access site or active systemic infection.
  • Subject has any condition that requires premature discontinuation of recommended antiplatelet and/or anticoagulant therapy before 90 days following the index procedure.
  • Any use of a mechanical circulatory support device within 14 days prior to the index procedure.
  • Staged PCI is planned within 90 days following device removal.
  • Subject is participating in another investigational drug or device study that has not reached its primary endpoint.
  • Subject has other disease condition(s) resulting in the subject being unsuitable for participation in the clinical trial (e.g., advanced malignancy with limited expected survival)
  • Subject has other disease condition(s) which the Investigator has determined may cause non-compliance to the study requirements.
