Value of psychosocial evaluation for left ventricular assist device candidates.
Left ventricular assist devices require a psychosocial assessment to determine candidacy despite limited data correlating with outcome. Our objective is to determine whether the Stanford Integrated Psychosocial Assessment for Transplant, a tool validated for transplant and widely used by left ventricular assist device programs, predicts left ventricular assist device program hospital readmissions and death. ⋯ Total Stanford Integrated Psychosocial Assessment for Transplant score was not associated with left ventricular assist device program readmission or mortality. However, we identified certain Stanford Integrated Psychosocial Assessment for Transplant components that were associated with outcome and could be used to create a left ventricular assist device program specific psychosocial tool.

Bioprosthetic versus mechanical mitral valve replacements in patients with rheumatic heart disease.
Rheumatic heart disease (RHD) remains a critical problem in developed countries. Few studies have compared the long-term outcomes of bioprosthetic valves and mechanical valves in patients with RHD who have received mitral valve (MV) replacement. ⋯ In the patients with RHD who underwent MV replacement, mechanical valves were associated with more favorable long-term outcomes in patients younger than the age of 65 years.

Same-teams versus different-teams for long distance lung procurement: A cost analysis.
In an era of broader lung sharing, different-team transplantation (DT, procuring team from nonrecipient center) may streamline procurement logistics; however, safety and cost implications of DT remain unclear. To understand whether DT represents a safe means to reduce lung transplant (LTx) costs, we compared posttransplant outcomes and lung procurement and index hospitalization costs among matched DT and same-team transplantation (ST, procuring team from recipient center) cohorts at a single, high-volume institution. We hypothesized that DT reduces costs without compromising outcomes after LTx. ⋯ At our institution, DT and ST were associated with similar post-LTx outcomes; DT offered cost-savings with increasing procurement travel distance. These findings suggest that DT may mitigate logistical and financial burdens of lung procurement; however, further investigation in a multi-institutional cohort is warranted.

Myeloperoxidase in the pericardial fluid improves the performance of prediction rules for postoperative atrial fibrillation.
After surgery, inflammation is a prominent factor influencing postoperative atrial fibrillation. Myeloperoxidase is a major contributor to inflammatory responses after surgical tissue damage. We evaluated whether myeloperoxidase is associated with postoperative atrial fibrillation clinically and in an animal model. ⋯ Myeloperoxidase is linked to postoperative atrial fibrillation, and the ability to predict postoperative atrial fibrillation was remarkably improved by adding pericardial myeloperoxidase. Myeloperoxidase-related atrial structural and electrical remodeling is a physiologic substrate for this arrhythmia.

A novel predictive model for poor in-hospital outcomes in patients with acute kidney injury after cardiac surgery.
Patients with cardiac surgery-associated acute kidney injury are at risk of renal replacement therapy and in-hospital death. We aimed to develop and validate a novel predictive model for poor in-hospital outcomes among patients with cardiac surgery-associated acute kidney injury. ⋯ We developed and validated a promising predictive model for in-hospital composite outcomes among patients with cardiac surgery-associated acute kidney injury and demonstrated interleukin-16 and interleukin-8 as useful predictors to improve risk stratification for poor in-hospital outcomes among those with cardiac surgery-associated acute kidney injury.
