Eligibility
Inclusion criteria
Inclusion criteria: 1)Serious heart failure or refractory cardiogenic shock due to the following diseases, which does not respond to optimal medication and mechanical support a.Underlying disorders causing serious heart failure or refractory cardiogenic shock 1.low cardiac output syndrome due to cardiac disorders (idiopathic, secondary or ischemic cardiomyopathy, or myocarditis) 2.post-acute myocardial infarction circulatory failures (including mechanic complication or refractory arrhythmia) 3. difficulty in withdrawal of cardiopulmonary bypass 4. postoperative low cardiac output syndrome (including refractory arrhythmia) 5. other cardiogenic circulatory failures (including refractory arrhythmia) b. Underlying disorders causing severe respiratory failure 1.severe infectious (viral or bacterial) and aspiration pneumonia 2.acute respiratory distress syndrome (ARDS) 3.bridge to lung transplantation, primary lung graft failure such as reperfusion injury 4.difficulty in withdrawal of cardiopulmonary support due to respiratory failure 5.transient respiratory failure in patients with chronic lung disease 6.heavy asthma attack 7.other acute respiratory failures 2) Body weight not lower than 10kg at the time of informed consent 3) Written informed consent of the patient or his/her relatives
Exclusion criteria
Exclusion criteria: 1) Unfavorable or technically-challenging cardiac anatomy 2) Evidence of irreversible hepatic disease (except when the primary investigator deems it as a sign of acute heart failure) 3) Evidence of irreversible renal disease (except when the primary investigator deems it as a sign of acute heart failure) 4) Contraindicated for anticoagulation 5) Difficulty of 14-day observation is anticipated 6) Participating in another clinical trial at time of study entry 7) Deemed unsuitable by the primary investigator for other reasons
