Complete Sternal-Sparing HeartMate 3 Implantation: A Case Series of 10 Consecutive Patients.

ABSTRACT

BACKGROUND: Left ventricular assist device (LVAD) therapy has been the standard of care for selected patients with advance heart failure. Even though considerable strides have been achieved with the introduction of the newest centrifugal pump, therapy is still burdened with significant perioperative complications. Smaller devices, along with improved techniques and instruments, have encouraged the adoption of minimally invasive cardiac surgery (MICS) techniques for LVAD implantation to improve perioperative outcomes. METHODS: We describe a technique for complete sternal-sparing (CSS) HeartMate 3 (Abbott Laboratories, Abbott Park, IL) left ventricular assist device (LVAD) implantation using bilateral thoracotomies and discuss early clinical outcomes of the first ten consecutive patients who underwent CSS implantation of the HeartMate 3 LVAD at our institution. RESULTS: The median length of stay in the intensive care unit was 3.5 days. No patients required reexploration for postoperative bleeding. There was no incidence of right ventricle failure, stroke, renal failure, hepatic failure, or myocardial infarction. The median length of hospitalization after LVAD implantation was 14.5 days (interquartile range, 12 to 17 days). CONCLUSIONS: Our early outcomes suggest that the CSS approach may reduce the incidence of right ventricular failure, bleeding, intubation time, and intensive care unit length of stay. Further studies are needed to fully elucidate the advantages of CSS LVAD implantation compared with median sternotomy.
