Outcomes of orthotopic heart transplantation and left ventricular assist device in patients aged 65 years or more with end-stage heart failure

Abstract

Age has traditionally been a limiting factor for advanced heart failure (HF) therapies. Orthotopic heart transplantation (OHT) age guidelines have become less restrictive, and left ventricular assist devices (LVADs) are increasingly utilized as destination therapy for patients ≥65 years. Although indications differ, we assessed outcomes for both modalities in this older population. We reviewed charts of consecutive advanced HF therapy recipients aged ≥65 years at our center from 2012 to 2016. Of 118 patients evaluated, 46 (39%) received an LVAD and 72 (61%) received OHT. Gender, body mass index, and rate of prior sternotomy were similar between groups; OHT recipients were younger, less likely to have diabetes mellitus, and more likely to have HF due to ischemic etiology. Forty-six percent of patients receiving LVADs were urgent need (Interagency Registry for Mechanically Assisted Circulatory Support [INTERMACS] profile 1–2), compared to 29% of patients receiving OHT (United Network for Organ Sharing 1A criteria; P = 0.068). OHT recipients had shorter lengths of stay and better 1-year survival compared to LVAD recipients. Although many centers do not offer advanced HF therapy to patients aged ≥65 years, our results indicate that age alone should not be prohibitive for advanced HF therapy, particularly OHT.
