Survival predictors in acute respiratory distress syndrome with extracorporeal membrane oxygenation.
Extracorporeal membrane oxygenation (ECMO) can be used as a salvage therapy, but the effectiveness is controversial. The aim of this study was to investigate the predictors of mortality and the influence of organ dysfunction scores in severe acute respiratory distress syndrome (ARDS) patients treated with ECMO. ⋯ Severe ARDS patients who are younger, have shorter duration of mechanical ventilation, and lower organ dysfunction scores before ECMO initiation have more favorable survival outcome. Early application of ECMO, especially if predictive score is below 2, may improve survival. Organ dysfunction scores before and during ECMO support are correlated with survival.

Postoperative atrial fibrillation (POAF) increases considerably the chances of morbidity and mortality after cardiac surgery. The objective of this study was to identify the major risk factors responsible for POAF after thoracic aortic surgery in order to define preventive measures. ⋯ Several risk factors contribute to the incidence of POAF after thoracic aortic surgery. We found that POAF significantly increased 30-day operative mortality (p < 0.0001). Our findings can be used to develop a risk stratification system for the prediction of POAF.

Multicenter Study
The association of transcatheter aortic valve replacement availability and hospital aortic valve replacement volume and mortality in the United States.
Whether the introduction of transcatheter aortic valve replacement (TAVR) has affected hospitals' surgical aortic valve replacement (SAVR) and overall aortic valve replacement (AVR) case volumes and outcomes in the United States is unknown. ⋯ Since the introduction of TAVR, the total volume of AVR procedures, including higher overall use of SAVR, at TAVR sites has significantly increased in the United States. Overall, in-hospital survival of patients undergoing treatment for aortic valve stenosis continues to improve.

Multicenter Study
Epidemiology and outcomes after in-hospital cardiac arrest after pediatric cardiac surgery.
Multicenter data regarding cardiac arrest in children undergoing heart operations are limited. We describe epidemiology and outcomes associated with postoperative cardiac arrest in a large multiinstitutional cohort. ⋯ Cardiac arrest carries a significant mortality risk across the stratum of procedural complexity. Although arrest rates are not associated with center volume, lower-volume centers have increased mortality after cardiac arrest. Further study of mechanisms to prevent cardiac arrest and to reduce mortality in those with an arrest is warranted.
