Descrizione
Inclusion Criteria:
- 18≤Age≤80, any sex.
- Failure to wean from CPB or refractory cardiogenic shock after cardiac surgery.
Failure to wean from CPB is defined as failed to discontinue CPB or post-weaning CI <2.2L/min/m2 + PCWP >15mmHg, despite optimal pre-weaning management and receiving at least one high dose inotrope.
Refractory cardiogenic shock is defined as a condition that occurs despite adequate fluid status and meets all the following criteria:
① CI<2.2L/min/m2 + PCWP>15mmHg despite receiving at least one high dose inotrope or IABP; OR SBP <80mmHg or MAP<50mmHg despite receiving at least one high dose intrope + high dose norepinephrine or IABP.
② Presence of at least one signs indicating hypoperfusion: decreased mentation; cold, clammy, ashen or cyanotic extremities or skin or livedo reticularis; urine output<30ml/h or 0.5ml/kg/h; or lactate>2mmol/L or metabolic acidosis.
- Patient has signed the informed consent form.
Exclusion Criteria:
- Body surface area>2.5m2.
- Presence of any cardiac assist device (other than an IABP).
- Right ventricular failure.
- Evidence of any vascular disease or anatomy precluding placement or deployment of the device (e.g. severely calcified vessel).
- Evidence of ventricular thrombus.
- Moderate or severe aortic valve insufficiency/stenosis, or severe aortic valve calcification.
- Presence of mechanical aortic valve or cardiac contractile device.
- Obstructive, hypertrophic cardiomyopathy.
- Presence of uncorrected ventricular septal defect, atrial septal defect or patent foramen ovale.
- Mechanical manifestation of AMI (e.g. ventricular septal rupture, papillary muscle rupture, ventricular rupture).
- Any hematological disorder causing fragility of blood vessel or hemolysis.
- Known allergy or intolerant to heparin.
- Presence or suspicion of active systemic infection.
- Cardiopulmonary resuscitative maneuver lasting longer than 20 minutes before device placement.
- Sustained or non-sustained ventricular tachycardia or ventricular fibrillation unresponsive to medical therapy.
- Severe hepatic dysfunction, renal failure or severe respiratory failure
- Pregnant or lactating female.
- Concomitant enrollment in another investigational drug or device study where the primary endpoint has not yet been completed or that will clinically interfere with the endpoint of this investigation.
- Other conditions considered unsuitable for participating in this investigation by the investigators.
