Background: Severe primary graft dysfunction (PGD) is a major cause of early mortality after heart transplant, but the impact of donor organ preservation conditions on severity of PGD and survival has not been well characterized.
Methods: Data from US adult heart-transplant recipients in the Global Utilization and Registry Database for Improved Heart Preservation-Heart Registry (NCT04141605) were analyzed to quantify PGD severity, mortality, and associated risk factors. The independent contributions of organ preservation method (traditional ice storage vs controlled hypothermic preservation) and ischemic time were analyzed using propensity matching and logistic regression.
Traditional ice storage has been the historic standard for preserving donor's hearts. However, this approach provides variability in cooling, increasing risks of freezing injury. To date, no preservation technology has been reported to improve survival after transplantation.

The authors hypothesized that adding liposomal bupivacaine (LB) to plain bupivacaine (PB) will provide better and long-lasting analgesia when used for wound infiltration in median sternotomy.
Study Design: Prospective, randomized, and double-blinded clinical trial.
Unlabelled: We aimed to investigate whether there are differences in outcome for pediatric patients when extracorporeal life support (ECLS) is initiated on-hours compared with off-hours.
Design: Retrospective cohort study.
Setting: Ten-year period (2009-2018) in United States centers, from the Extracorporeal Life Support Organization registry.
This study evaluated differences in efficacy and safety outcomes with bivalirudin compared with unfractionated heparin (UFH) in patients with cardiogenic shock requiring venoarterial extracorporeal membrane oxygenation (VA ECMO). We performed a retrospective study at an academic medical center that included patients greater than 18 years of age supported with VA ECMO due to cardiogenic shock from January 2009 to February 2021. The primary endpoint was ECMO-associated thrombotic events normalized to duration of ECMO support.

CCI scores have not been validated in cardiac surgical patients. We hypothesize that the CCI will predict mid-term mortality and re-admissions, but performance may be different than purpose-built cardiac surgery risk calculators.

The incidence, risk factors, and outcomes of consensus-defined PGD warrant further investigation. We retrospectively examined 448 adult cardiac transplant recipients at our institution from 2005 to 2017.

The patient was successfully bridged to heart transplantation using additional right-sided support with Protek Duo.

We summarize our experience with desensitization using carfilzomib, an irreversible proteasome inhibitor that causes plasma cell apoptosis.
Methods: One cycle of desensitization consisted of plasmapheresis and carfilzomib 20 mg/m on days 1, 2, 8, 9, 15, and 16 with intravenous immune globulin 2 g/kg after carfilzomib on day 16.
Objectives: Extracorporeal membrane oxygenation is a life-sustaining therapy for severe respiratory failure. Extracorporeal membrane oxygenation circuits require systemic anticoagulation that creates a delicate balance between circuit-related thrombosis and bleeding-related complications. Although unfractionated heparin is most widely used anticoagulant, alternative agents such as bivalirudin have been used.

Methods: Adults undergoing primary LVAD placement from April 2004 to May 2017 were included.
Background: Studies examining one-year mortality respecting component blood transfusion are sparse. We hypothesize that component blood product transfusions are negatively associated with 90-day and 1-year survival for all patients requiring veno-arterial (VA) or veno-venous (VV) ECMO.
Study Design And Methods: This was an IRB-approved retrospective cohort analysis of 676 consecutive patients requiring ECMO at the University of Pittsburgh between 2005 and 2016.
Background: Ventricular assist device (VAD) patients are at high risk for morbidities and mortality. One potentially beneficial component of the Joint Commission VAD Certification process is the requirement that individual VAD programs select 4 performance measures to improve and optimize patients' clinical outcomes.
Problem Statement: Review of patient data after our program's first certification visit in 2008 showed that, compared to national recommendations and published reports, our patients had suboptimal outcomes in 4 areas after device implantation: length of hospital stay, receipt of early (<48 hours) postsurgical physical therapy, driveline infection incidence, and adequacy of nutritional status (prealbumin ≥18 mg/dL).
Background: This study delineates the sequences of adverse events (AEs) preceding mortality attributed to multisystem organ failure (MSOF) in patients with a left ventricular assist device (LVAD).
Methods: We analyzed 3765 AEs after 536 LVAD implants recorded in The Society of Thoracic Surgeons Intermacs data registry between 2006 and 2015 that resulted in MSOF death. Hierarchical clustering identified and visualized quantitatively unique clusters of patients with similar AE profiles.
Background: The aim of this study was to evaluate outcomes of left ventricular assist devices (LVADs) in patients who tested positive for hypercoagulable hematologic disorders.
Methods: Adults undergoing continuous-flow LVAD implantation with preoperative hypercoagulability testing between 2004 and 2018 at a single center were reviewed. Hypercoagulability was defined as testing positive for antiphospholipid antibody, anticardiolipin antibody, lupus anticoagulant, protein C, protein S, factor V Leiden, and/or heparin-induced thrombocytopenia.
Background: Social determinants of health, including neighborhood socioeconomic status (NSES), are increasingly being associated with disparate outcomes in those undergoing cardiac procedures. The objective of this study was to determine the effect of NSES on outcomes after coronary artery bypass grafting (CABG).
Methods: Adults undergoing isolated CABG between July 2011 and December 2017 were retrospectively reviewed.
Background: Psychosocial evaluations are required for long-term mechanical circulatory support (MCS) candidates, no matter whether MCS will be destination therapy (DT) or a bridge to heart transplantation. Although guidelines specify psychosocial contraindications to MCS, there is no comprehensive examination of which psychosocial evaluation domains are most prognostic for clinical outcomes. We evaluated whether overall psychosocial risk, determined across all psychosocial domains, predicted outcomes, and which specific domains appeared responsible for any effects.

Methods: This was a randomised, prospective, open-label trial. Patients undergoing elective cardiac surgery (n=116) were randomised to receive either continuous intravenous remifentanil infusion or intermittent fentanyl boluses.
Introduction: Data comparing sedatives in patients receiving extracorporeal membrane oxygenation (ECMO) are sparse. However, it is known that the ECMO circuit alters the pharmacokinetic properties of medications via drug sequestration of lipophilic agents and increased volume of distribution.
Objectives: This study evaluated the difference in days alive without delirium or coma and the sedative requirements in patients receiving fentanyl versus hydromorphone in ECMO patients.

Introduction: Extracorporeal cardiopulmonary resuscitation (ECPR) can treat cardiac arrest refractory to conventional therapies. Many institutions are interested in developing their own ECPR program. However, there may be challenges in logistics and implementation.

Nor are there any guidelines pertaining to the patient with type B aortic dissection.

Computed tomography of the chest demonstrated numerous pulmonary nodules and mass-like pulmonary lesions, and subsequent cardiac magnetic resonance imaging demonstrated an infiltrating mass-like lesion within the interventricular septum and pericarditis. Endobronchial, thoracoscopic, and eventual myocardial biopsies with cultures were ultimately reported as positive for species and the patient was treated with tailored antifungal therapy resulting in a significant therapeutic response upon short interval follow-up.
