We report a case of a 59-year-old man who presented with fever, sepsis, and left cervicothoracic cutaneous inflammation 13 months after implantation of Jarvik 2000 device. Device infection was suspected and F-FDG PET/CT showed an intense and homogeneous uptake along driveline cable. Bacteriological local sample showed Staphylococcus aureus. After adapted antibiotherapy, control F-FDG PET/CT displays treatment efficacy with no residual uptake in driveline. F-FDG PET/CT could be an important tool for early noninvasive detection of left ventricular assist device infection and monitoring antibiotherapy response...

Over the last few decades, the left ventricular assist device (LVAD) technology has been tremendously improved transitioning from large and noisy paracorporeal volume displacement pumps to small implantable turbodynamic devices with only a single transcutaneous element, the driveline. Nevertheless, there remains a great demand for further improvements to meet the challenge of having a robust and safe device for long-term therapy. Here, we review the state of the art and highlight four key areas of needed improvement targeting long-term, sustainable LVAD function: (1) LVADs available today still have a high risk of thromboembolic and bleeding events that could be addressed by the rational fabrication of novel surface structures and endothelialization approaches aiming at improving the device hemocompatibility...

New generation devices for long-term mechanical circulatory support are centrifugal pumps having fully magnetically levitated rotors to reduce blood trauma. Recently, the novel HeartMate 3 was cleared for clinical application in Switzerland. In two Swiss University Hospitals part of the "Lausanne-Geneva Transplantation Network," 10 consecutive patients in end-stage heart failure received the HeartMate 3. Device implantation criteria were persistent low output syndrome despite optimal medical treatment. The primary end-point of the study was survival or transplantation to 90 days on the device...

PURPOSE: A continuous-flow left ventricular assist device (LVAD) is a new and highly promising therapy in supporting end-stage heart failure patients, either bridging them to heart transplantation or as a destination therapy. Infection is one of the major complications associated with LVAD implants. (18)F-FDG PET/CT has already been shown to be useful in the detection of LVAD infection. The goal of this study was to compare the diagnostic accuracy of different PET analysis techniques (visual grading versus SUVmax and metabolic volume)...

A 64-year-old man experienced a driveline infection that was treated with serial debridements and antibiotics. When the wound clinically appeared ready for closure, a handheld fluorescence imaging device still revealed a margin of red fluorescence around the wound edges consistent with a subclinical infection. Therefore, a wider margin was made and additional specimens for wound culture were taken, which demonstrated a vancomycin-resistant enterococcal infection. The autofluorescence signals of common bacteria can be detected with a fluorescence camera in subclinical wound infections without clinical signs...

Long-term survival after left ventricular assist device (LVAD) implantation in heart failure patients is mainly determined by a sophisticated after-care. Ambulatory visits only take place every 12 weeks. In case of life-threatening complications (pump thrombosis, driveline infection) this might lead to delayed diagnosis and delayed intervention. It is the intention of the international project Medolution (Medical care evolution) to develop new approaches in order to create best structures for telemonitoring of LVAD patients...

BACKGROUND: Heart failure is a major cause of mortality and morbidity, particularly among patients with advanced disease and no access to cardiac transplantation. LVAD implantation is not only a bridge-to-transplantation option for patients awaiting a heart donor, but is often used as bridge-to-destination therapy in patients unsuited for transplantation for various reasons. LVAD infection is considered the second-most common cause of death in patients who survive the initial 6 months on LVAD support...

BACKGROUND: Left ventricular assist device (LVAD) exit-site infections represent a major challenge in the era of modern LVADs. Infections caused by Pseudomonas are particularly difficult to treat due to limited antibiotic susceptibility. We hypothesized that keeping the LVAD exit site dry while bathing could result in reduced incidence of Pseudomonas infections. METHODS: Starting in April 2013, all patients who underwent placement of HeartMate II (HM II) LVAD were instructed not to take conventional showers and to keep the exit site dry while bathing...

To manage myocardial recovery in patients with the HeartWare left ventricular assist device (HVAD), we describe a minimally invasive approach (decommissioning) that involves disconnecting the driveline and occluding the outflow tract through a small left thoracotomy incision, leaving the device in situ, in conjunction with optimal medical therapies and comprehensive assessment of left ventricular recovery. Nine patients (all male, 37 ± 12 years, all nonischemic dilated cardiomyopathy) had an HVAD implanted for 766 ± 343 days...

There are currently no guidelines for the management of infection and its prevention in mechanical circulatory support (MCS) device recipients. The International Society of Heart and Lung Transplantation (ISHLT) has initiated a multidisciplinary collaboration for the creation of a consensus document to guide clinicians in infection prevention and management in MCS patients. Most medical centers use local protocols that are based on expert opinion. MCS recipients are debilitated and have some immunological dysfunction...

BACKGROUND: The use of mechanical circulatory support devices (MCSDs) has been increasing over the past several years. Driveline infections (DLIs) are one of the most common complications seen in these patients; reportedly, up to 50% of patients with MCSDs can develop this complication. It is believed that the removal of the driveline results in treatment of the localized infection area. MCSD patients are also known to develop circulating antibodies. These circulating antibodies have been associated with poor outcomes after heart transplantation...

Because the first generation of pulsatile-flow devices was primarily used to bridge the sickest patients to transplantation (bridge-to-transplant therapy), the current generation of continuous-flow ventricular assist devices qualifies for destination therapy for patients with advanced heart failure who are ineligible for transplantation. The first-generation devices were associated with frequent adverse events, limited mechanical durability, and patient discomfort due device size. In contrast, second-generation continuous-flow devices are smaller, more quiet, and durable, thus resulting in less complications and significantly improved survival rates...
