Decommission of a Heartmate 3 LVAD in a patient with left ventricular recovery

Stephen Shannon et al. J Card Surg. 2022 Dec.

Abstract

Background: Left ventricular assist devices (LVADs) have been a significant development in the treatment of patients with advanced heart failure supporting circulation as a bridge to transplant, recovery, or long-term destination therapy. When ventricular recovery occurs, there are multiple described ways of proceeding. HM2 decommissions are well described with varying degrees of explant operations, less so in HM3 due to the novelty of the device. In certain situations, invasive surgery can carry high risk and so a minimally invasive decommission, leaving the LVAD essentially intact in situ can be considered.

Case report: In this report, we describe the case of a 35-year-old male diagnosed with an idiopathic dilated cardiomyopathy requiring an LVAD with subsequent identification of cardiac recovery with the asymptomatic thrombosis of the second HM3 device. Investigations demonstrated absent flow through the pump whilst the patient-reported NYHA I functional class symptoms. The Driveline was cut with the remaining internal pump components decommissioned and left in situ. At 1 year, the patient continues to do well with continued features of cardiac recovery with an LVEF of over 40%.

Conclusion: LV recovery is well recognized with typical management being LVAD explant surgeries performed. Each case should be analyzed for risks and benefits to the patient and future research showed be directed towards levels of decommissioning surgery and management post-LVAD decommission patient care.
