Machine Learning Models to Predict Major Adverse Cardiovascular Events After Orthotopic Liver Transplantation: A Cohort Study.
To develop machine learning models that can predict post-transplantation major adverse cardiovascular events (MACE), all-cause mortality, and cardiovascular mortality in patients undergoing liver transplantation (LT). ⋯ Machine learning models developed using data from a tertiary care transplantation center achieved good discriminant function in predicting post-LT MACE, all-cause mortality, and cardiovascular mortality. These models can support clinicians in recipient selection and help screen individuals who may be at elevated risk for post-transplantation MACE.

EACTA/SCA Recommendations for the Cardiac Anesthesia Management of Patients With Suspected or Confirmed COVID-19 Infection: An Expert Consensus From the European Association of Cardiothoracic Anesthesiology and Society of Cardiovascular Anesthesiologists With Endorsement From the Chinese Society of Cardiothoracic and Vascular Anesthesiology.
The European Association of Cardiothoracic Anaesthesiology (EACTA) and the Society of Cardiovascular Anesthesiologists (SCA) aimed to create joint recommendations for the perioperative management of patients with suspected or proven severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection undergoing cardiac surgery or invasive cardiac procedures. To produce appropriate recommendations, the authors combined the evidence from the literature review, reevaluating the clinical experience of routine cardiac surgery in similar cases during the Middle East Respiratory Syndrome (MERS-CoV) outbreak and the current pandemic with suspected coronavirus disease 2019 (COVID-19) patients, and the expert opinions through broad discussions within the EACTA and SCA. The authors took into consideration the balance between established procedures and the feasibility during the present outbreak. ⋯ As the COVID-19 pandemic is spreading, it will continue to present a challenge for the worldwide anesthesiology community. To allow these recommendations to be updated as long as possible, the authors provided weblinks to international public and academic sources providing timely updated data. This document should be the basis of future task forces to develop a more comprehensive consensus considering new evidence uncovered during the COVID-19 pandemic.

Case ReportsOn-Table Verification of Aortopulmonary Shunt Patency Through Ipsilateral Pulmonary Venous Blood Flow Assessment by Transesophageal Echocardiography.
Intraoperative transesophageal echocardiography is a well-established modality for the evaluation of the adequacy of the surgical repair of complex congenital heart lesions. This case report highlights the important role played by real-time transesophageal echocardiography during the evaluation of the patency of a left modified Blalock-Taussig shunt in a child with pulmonary atresia, nonconfluent pulmonary arteries, and borderline hemodynamic/ventilator parameters. Changes observed in the pulmonary venous blood flow pattern provided reassurance to the surgical team about the patency of the shunt and thereby avoided its reconstruction.

Elevated Prosthetic Valve Gradients: What to Consider When Determining an Etiology.
DOPPLER echocardiography is a useful noninvasive tool for the assessment of cardiac hemodynamics. However, it is subject to limitations that can have important clinical implications, especially in the setting of valve prosthesis. Elevation in mean transvalvular gradient is a finding that has a variety of etiologies. ⋯ The elevated gradient measured with Doppler echocardiography as a result of PR is not present on cardiac catheterization and does not represent true problematic valve hemodynamics. PR should be suspected with an elevated gradient on Doppler echocardiography with normal leaflet motion, especially in the setting of a small proximal aorta. Understanding and awareness of PR are important because PR can lead to overestimation of disease severity in the clinical setting.

Controversies in the Clinical Practice of Patient Blood Management.
Patient blood management (PBM) has been proposed as a standard of care in modern perioperative medicine. PBM-related interventions usually are implemented as bundles, but randomized controlled trials on the implementation of PBM as a bundle are missing. ⋯ Strong evidence for many PBM-related interventions is limited because of missing studies or the poor quality of published findings and study endpoints. Restrictive blood transfusion and timely interventions to maintain hemoglobin concentration and to reduce blood loss potentially might result in improved patient outcome, although the latter has yet to be proven.
