Real-Time Autofluorescence Imaging to Diagnose LVAD Driveline Infections

The Annals of Thoracic Surgery
Jack B KeenanZain Khalpey

Abstract

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. Here we describe the first use of this technology to diagnose ventricular assist device driveline infections after left ventricular assist device implantation.
