Electroconvulsive Therapy in a Left Ventricular Assist Device Recipient With Treatment-Resistant Depression.

Abstract: Depression and heart failure are highly comorbid, with up to 35% of heart failure patients suffering from comorbid depression. Left ventricular assist devices (LVADs) serve as a major lifeline for patients with heart failure; however, despite the drastic improvement in cardiac function following LVAD implantation, up to 24% of LVAD recipients suffer from depression. Depression management in LVAD recipients is often complicated by the recipient's increased risk for antidepressant side effects, adverse drug reactions, and inability to safely receive certain interventional psychiatry therapies, as the LVAD is either a relative or absolute contraindication. Electroconvulsive therapy (ECT) is highly effective for treatment-resistant depression; although it carries increased cardiovascular risks for the LVAD population (particularly bradycardia/hypotension and tachycardia/hypotension), these can be continuously monitored, along with LVAD function, such that with the close cooperation of a multidisciplinary team, the risks of ECT can be minimized. To our knowledge, there is only one published case report of ECT in an LVAD recipient. We present a case of an LVAD recipient with treatment-resistant depression who was successfully treated with ECT. Our case describes an approach by which ECT can be safely delivered to LVAD recipients with a collaborative multidisciplinary team approach.
