Perioperative Stroke Following Implantation of Left Ventricular Assist Device: A Retrospective Cohort Study.

Objectives: Stroke is common following left ventricular assist device (LVAD) implantation, although comprehensive data on perioperative strokes in this uncommon population is lacking. The current study aim was to characterize the presentation, features, and outcomes of perioperative cerebrovascular ischemia post-LVAD implantation at the authors' institution.

Design: Single-center retrospective cohort.

Indications and Techniques for Surgical Lead Extraction and Device Reimplantation.

Cardiac implantable electronic devices (CIEDs) can be lifesaving but complications associated with CIEDs can lead to significant morbidity and mortality. Effective techniques to remove these devices are critical to reducing complications and improving quality of life. Percutaneous extraction techniques are effective for removing the majority of CIEDs but surgical lead extraction is still required in certain situations.

Effects of Implantable Cardioverter-Defibrillator Leads on the Tricuspid Valve and Right Ventricle: A Randomized Trial.

Background: There are no randomized data to inform the extent to which transvenous cardiac leads cause tricuspid regurgitation (TR).

Objectives: This study sought to determine the effect of a transvenous implantable cardioverter-defibrillator (TV-ICD) on TR severity, and secondarily, on right ventricular (RV) size and function.

Methods: We evaluated TR severity before and 6 months after implantable cardioverter-defibrillator insertion in a post hoc analysis of adults randomized to receive a transvenous (n = 252) or subcutaneous implantable cardioverter-defibrillator (S-ICD) (n = 251) device.

A band gap and photoluminescence properties engineering in BaO semiconductor for ultraviolet (UV) photodetector applications: A comprehensive role of co-doping.

We report on ultra-violet (UV) photodetectors based on BaO nanoparticles by the detailed investigation of band gap and photoluminescence properties. The BaO nanomaterials were fabricated by the modified sol-gel technique. The innovation of co-doping can modulate the photoluminescence or sensing properties by narrowing the band gap related to enhancing the high carrier concentration, higher electronic lifetime, and low carriers recombination.
