Article Synopsis
  • Intraoperative implantation of leadless cardiac pacemakers (LCPs) during valve surgery is a new approach intended for patients at high risk of postoperative heart conduction issues.
  • A study assessing the long-term safety and effectiveness of this method evaluated 100 patients, all of whom underwent successful LCP implantation without any device-related complications during an average follow-up of about 10.6 months.
  • Results showed that 95% of patients had acceptable pacing thresholds at the 12-month follow-up, indicating that this technique is a safe alternative to traditional pacing methods.

Objectives: To describe the trend in plasma renin activity over time in patients undergoing cardiac surgery on cardiopulmonary bypass, and to investigate if increased plasma renin activity is associated with postcardiopulmonary bypass vasoplegia.

Design: A prospective cohort study.

Setting: Patients were enrolled from June 2020 to May 2021 at a tertiary cardiac surgical institution.

Introduction: Axial-flow and centrifugal-flow left ventricular assist devices (LVAD) have been utilized in the management of heart failure, but it remains unknown whether these devices differ in end-organ perfusion. Our goal was to evaluate the association between device type and regional cerebral oxygen saturation (rSO), and determine if this confers any benefit in short-term postoperative outcomes.

Methods: Adult patients who underwent primary LVAD implantation at our institution from 2014 to 2019 were retrospectively analyzed.

Objective: The leadless cardiac pacemaker is typically implanted percutaneously and has been widely used for patients who have already undergone valve surgery. We sought to determine the feasibility and safety of implanting the leadless pacemaker under direct visualization during valve surgery.

Methods: We performed a retrospective analysis of consecutive adult patients (n = 15) who underwent implantation of a leadless pacemaker under direct visualization at the time of valve surgery.

Introduction: The subcutaneous implantable cardioverter-defibrillator (S-ICD) is most commonly implanted under general anesthesia (GA), due to the intraoperative discomfort associated with tunneling and dissection. Postoperative pain can be substantial and is often managed with opioids. There is a growing interest in transitioning away from the routine use of GA during S-ICD implantation, while also controlling perioperative discomfort without the use of narcotics.
