C onsiderable attention is currently being focused on the development of intravascular and intracardiac ultrasound imaging.1-4 Variously termed as "ultrasound angioscopy," "intravascular ultrasound imaging," or "intraluminal ultrasound imaging," this technique basically refers to the imaging modality of visualizing blood vessels and cardiac structures by an ultrasound transducer placed at the t...

We encountered cardiac arrest induced by 0.375 % ropivacaine 7 ml administered via a catheter for continuous thoracic paravertebral block (TPVB) in a 6-year-old female who underwent pacemaker implantation for sick sinus syndrome (SSS). She was successfully resuscitated with adrenaline and lipid emulsion. Plasma concentration of ropivacaine was 5.2 μg/ml, suggesting intravascular administration ...

BACKGROUND To enable intravascular detection of inflammation in atherosclerosis, we developed a near-infrared fluorescence (NIRF) catheter-based strategy to sense cysteine protease activity during vascular catheterization. METHODS AND RESULTS The NIRF catheter design was based on a clinical coronary artery guidewire. In phantom studies of NIRF plaques, blood produced only a mild (<30%) attenu...

The manufacturing of intravascular imaging coils poses several challenges. Due to their size, it can be difficult to incorporate local matching networks and signal amplifiers. The goal of this study is to investigate tuning and amplification strategies for intravascular coils and to assess the signal-to-noise benefits of incorporating a matching network and/or miniature amplifier into catheter-...

Enterococcal bloodstream infection (BSI) is associated with high morbidity and mortality. Interestingly, enterococcal BSI central-line (CLABSI) or intravascular devices (catheter-related BSI, CRBSI) has shown an increasing incidence proportion [[1]Novosad S.A. Fike L.
