RESUMO
BACKGROUND: Postcardiotomy heart failure is still the main cause of death in patients undergoing palliative surgery for end-stage dilative cardiomyopathy. New micro-axial flow ventricular assisting devices (LVAD) have been suggested in such cases. OBJECTIVE: Evaluate the effect of the new LVAD on short-term outcome of a patient admitted for end-stage heart failure. STUDY DESIGN: Case report. DATA SOURCES: One patient admitted for severe mitral regurgitation secondary to end-stage dilative cardiomyopathy and chronic atrial fibrillation (AF). INTERVENTION: Preoperative intraaortic balloon pump (IABP) insertion, mitral plasty with radiofrequency ablation of AF, microaxial flow LVAD support. RESULTS: The patient was unweanable from cardiopulmonary bypass until microaxial flow LVAD unloaded the left ventricle and restored adequate cardiac function. The patient was discharged home and is still well at 5 months folllow-up. CONCLUSIONS: The miniinvasive insertion and withdrawal, low anticoagulation protocols, and the possibility of coupling with IABP make the microaxial flow LVAD promising for patients with end-stage heart failure undergoing surgery.
