Abstract : Left ventricular assist devices are implanted in patients with chronic left heart failure refractory to maximal medical therapy. These devices were initially meant as bridge-to-transplant therapy, but with technological advances they are now also used as destination therapy. With improved survival, many patients with implanted devices need noncardiac surgery. We present three representative cases of noncardiac surgery in such patients to highlight the issues involved in their management. We also review the contemporary literature on various aspects of perioperative management. Anesthesia for noncardiac surgery in these patients was initially the domain of cardiac anesthesiologists, but with an increasing number of such patients needing surgery, general anesthesiologists are frequently tasked to provide anesthetic care. An understanding of left ventricular assist device physiology and issues unique to these patients is essential for safe management of these cases.
