Introduction: The physiologic derangements imposed by cardiopulmonary bypass (CPB) can result in complications such as postoperative delirium. We aim to validate a rodent survival model of CPB demonstrating a systemic inflammatory response and hypothesize that this contributes to post-CPB delirium.

Methods: Adult Sprague-Dawley rats were randomized to three groups: 1) Sham peripheral surgical cannulation, 2) CPB followed by acute phase harvest, or 3) CPB followed by 24-h survival.

Objective: Optimal temporal surgical management of significant carotid stenosis and coronary artery disease remains unknown. Carotid endarterectomy (CEA) and coronary artery bypass (CABG) are performed concurrently (CCAB) or in a staged (CEA-CABG or CABG-CEA) approach. Using the Vascular Quality Initiative-Vascular Implant Surveillance and Interventional Outcomes Coordinated Registry Network-Medicare-linked dataset, this study compared operative and long-term outcomes after CCAB and staged approaches.

Introduction: Mainstays of current treatment for acute respiratory distress syndrome (ARDS) focus on supportive care and rely on intrinsic organ recovery. Animal models of ARDS are often limited by systemic injury. We hypothesize that superimposing gastric aspiration and ventilator-induced injury will induce a lung-specific injury model of severe ARDS.

Background: Many residency programs struggle to meet the ACGME requirement for resident participation in quality improvement initiatives.

Study Design: As part of an institutional quality improvement effort, trainees from the Departments of Surgery and Anesthesiology at a single academic medical center were teamed with institutional content experts in 7 key risk factor areas within preoperative patient optimization. A systematic review of each subject matter area was performed using the MEDLINE database.

Sepsis is the leading cause of acute respiratory distress syndrome (ARDS) in adults and carries a high mortality. Utilizing a previously validated porcine model of sepsis-induced ARDS, we sought to refine our novel therapeutic technique of in vivo lung perfusion (IVLP). We hypothesized that 2 hours of IVLP would provide non-inferior lung rehabilitation compared to 4 hours of treatment.

Background: Permanent pacemaker (PPM) implantation has been touted as an inconsequential complication after transcatheter aortic valve replacement. As transcatheter aortic valve replacement moves to lower risk patients, the long-term implications remain poorly understood; therefore, we evaluated the long-term outcomes of pacemaker for surgical aortic valve replacement patients.

Methods: A total of 2,600 consecutive patients undergoing surgical aortic valve replacement over the past 15 years were reviewed using The Society of Thoracic Surgeons (STS) institutional database and Social Security death records.
