Ruptured Intracranial Mycotic Aneurysm in Infective Endocarditis With Left Ventricular Assist Device and Implantable Cardiac Defibrillator Device: A Clinical Course.

We report the first case of a ruptured intracranial aneurysm-related Staphylococcus epidermidis bacteremia in a patient supported by a continuous flow left ventricular assist device (LVAD). Mycotic aneurysms (MAs) are aneurysmal degeneration of the arterial wall as a result of infection. Current recommendations for management of intracranial mycotic aneurysms are based on a few retrospective case studies. There are only a few cases of intracranial MA reported in patients with LVAD infections caused by Pseudomonas aeruginosa and Klebsiella rhinos. Here, we describe the first case of a ruptured intracranial aneurysm caused by a less virulent organism (Staphylococcus epidermidis) and conclude that screening for asymptomatic MA should be strongly considered in patients with persistent LVAD- and implantable cardiac defibrillator pacemaker-associated infections.
