Short- and long-term survival of patients transferred to a tertiary care center on temporary extracorporeal circulatory support.

Background: Mechanical circulatory support (MCS) with temporary, extracorporeal assist devices restores hemodynamics in patients with refractory cardiogenic shock. These devices are frequently used in community hospitals, with subsequent referral to tertiary care centers. We sought to determine the outcomes of such referrals and identify prognostic variables that may influence management decisions.
