Pneumonectomy Space Infection After Thoracic Duct Embolization.

Thoracic duct embolization has gained widespread acceptance as an effective treatment of postoperative chylothorax. We describe a patient with chylothorax after pneumonectomy requiring thoracic duct embolization who presented again with a pneumonectomy space infection. Bacterial culture was positive for gastrointestinal flora, which suggests that the pleural space was inoculated at the time of thoracic duct embolization.

Risk and Reward: Nationwide Analysis of Cardiac Transplant Center Variation in Organ Travel Distance and the Effects on Outcomes.

Background: The 2018 UNOS allocation policy change deprioritized geographic boundaries to organ distribution, and the effects of this change have been widespread. The aim of this investigation was to analyze changes in donor transplant center distance for organ travel and corresponding outcomes before and after the allocation policy change.

Methods: The UNOS database was utilized to identify all adult patients waitlisted for heart transplants from 2016 to 2021.

Transmediastinal primary pulmonary liposarcoma: Case report and review of management strategies.

Soft tissue sarcomas account for less than 1% of new cancer diagnoses, approximately one in five of which are liposarcomas. These tumors typically arise in the deep tissues of the proximal extremity or retroperitoneum, with just under 3% presenting as primary intrathoracic neoplasms. We present an exceedingly rare and particularly unique presentation of primary lung liposarcoma which traversed the mediastinum into the contralateral hemithorax.

The development of Logix - An application for component-based case logging and surgical trainee assessment.

Background: The optimal training program to transform a new resident into a competent and capable surgeon is constantly evolving. Competency-based evaluation represents a change in mindset from quantitative or chronologic metrics for graduate readiness. As surgery becomes more specialized, more dependent on technology, and more public, we must continue to improve our ability to pass on technical skills.

Heartmate 3 Left Ventricular Assist Device Bend Relief Disconnection Causing Laceration of the Outflow Graft.

As technology in mechanical circulatory support continues to advance, so does the utilization of durable left ventricular assist devices (LVADs). We present the first reported case of HeartMate 3 (HM3) LVAD bend relief disconnection causing laceration of the outflow graft. Our patient is a 34 year old male with end-stage heart failure status post-HM3 implantation with recent debridement of a driveline infection who presented with weakness and sanguineous drainage 5 days after an episode of heavy lifting associated with a palpable substernal pop.

Proof of Concept: Development of a Mitral Annuloplasty Ring With Crosshatch Net.

Objective: Here we report our preclinical, proof-of-concept testing to assess the ability of a novel device to correct mitral regurgitation. The Milwaukee Heart device aims to enable any cardiac surgeon to perform high-quality mitral valve repair using a standard annuloplasty ring with a crosshatch of microporous, monofilament suture.

Methods: Hemodynamic, echocardiographic, and videographic data were collected at baseline, following induction of mitral regurgitation, and after repair using porcine hearts in an ex vivo biosimulator model.

A model for delivery of extracorporeal life support in a stand-alone veterans affairs medical center.

Introduction: For the Veterans Health Administration (VHA) to continue to perform complex cardiothoracic surgery, there must be an established pathway for providing urgent/emergent extracorporeal life support (ECLS). Partnership with a nearby tertiary care center with such expertise may be the most resource-efficient way to provide ECLS services to patients in post-cardiotomy cardiogenic shock or respiratory failure. The goal of this project was to assess the efficiency, safety, and outcomes of surgical patients who required transfer for perioperative ECLS from a single stand-alone Veterans Affairs Medical Center (VAMC) to a separate ECLS center.

Supporting the right ventricle in postcardiotomy renal dysfunction: A case series.

Postcardiotomy RV dysfunction is an under-recognized cause of acute kidney injury (AKI). Insertion of a percutaneous right ventricular assist device (RVAD) reduces central venous hypertension and congestive nephropathy by augmenting cardiac output. In selected patients, percutaneous RVAD insertion may improve renal function and obviate the need for long-term dialysis.

The effect of socioeconomic factors on patient outcomes in cardiac surgery.

Objectives: Healthcare delivery is heterogenous; the reasons for this are numerous and complex. Patient-specific factors including geography, income, insurance status, age, and gender have been shown to bias surgical outcomes. Utilizing a prospectively collected all-payer database, we aim to evaluate the influence of socioeconomic factors on mortality and length of stay (LOS) after common cardiac surgical procedures.

Clinical and Quality of Life Outcomes After Lung Volume Reduction Surgery.

Background: Lung volume reduction surgery (LVRS) is the definitive treatment for patients with severe emphysema. There is still a need for long-term data concerning the outcomes of this procedure. This study presents long-term longitudinal data on LVRS including correlation of quality of life (QOL) with pulmonary function testing metrics and includes additional analysis of patients with heterogeneous and homogeneous emphysema.
