Abstract

Atrial fibrillation (AF) is known to be one of the most common arrhythmias noted in cardiac procedures and is frequently associated with heart failure. As frequent interventions for patients with heart failure involve implantation of mechanical circulatory assist devices (e.g., left ventricular assist devices), it is timely to review the role this arrhythmia has on adverse clinical outcomes. A comprehensive literature search was conducted for PubMed. Relevant medical subject heading (MeSH) terms used in the initial literature search include “Heart-Assist Devices”, “Extracorporeal Membrane Oxygenation”, “Atrial Fibrillation”, “Heart Failure”, “Mortality”, “Hospital Readmission”, “stroke”, “Postoperative Complications”. In this review, the relevant literature was highlighted to identify the incidence, clinical impacts, and management of AF surrounding mechanical circulatory support implantation. The incidence of AF in this mechanical circulatory support device population was similar to that of patients with other cardiac procedures (10%-40%). Moreover, in most studies, preoperative AF was not significantly associated with adverse outcomes. In contrast, however, it appears that postoperative atrial fibrillation may predispose patients to increased risk for thromboembolic events and adverse long-term outcomes.
