Mechanical assist strategy using the BVS 5000i for patients with heart failure

Background. The BVS 5000i external pulsatile assist device is used to suppo rt patients with reversible cardiogenic shock. Its low cost and potential f or insertion without cardiopulmonary bypass make it an attractive option. Methods. Nineteen status I patients failing inotropic support were treated with the BVS 5000i with the intention of short-term bridge to transplant. F ourteen patients received left: ventricular support whereas 5 received bive ntricular support. Cardiopulmonary bypass was used in less than 50% of pati ents. Results. Median support time was 7 days. The 2 myocarditis patients were we aned from support. Twelve patients were transplanted and there were 5 death s on support. Overall 14 of 19 were transplanted or weaned. One-year surviv al was 79%. Median hospital stay was 31 days. Conclusions. The BVS 5000i can be used for short-term mechanical assist tow ard transplantation in selected patients for whom a donor can be expected s oon. The device may provide a cost-effective, short-term strategy to optimi ze end-organ function before orthotopic heart transplant, particularly for patients who are predictably not ideal to be discharged with implantable le ft ventricular assist device treatment.
