Artificial intelligence has the potential to improve the care that is given to patients; however, the predictive models created are only as good as the base data used in their design. Perioperative blood management presents a complex clinical conundrum in which significant variability and the unstructured nature of the required data make it difficult to develop precise prediction models. There is a potential need for training clinicians to ensure they can interrogate the system and override when errors occur...

OBJECTIVE: The aortic-to-radial arterial pressure gradient is described during and after cardiopulmonary bypass (CPB), and can lead to underestimating arterial blood pressure. The authors hypothesized that central arterial pressure monitoring would be associated with lower norepinephrine requirements than radial arterial pressure monitoring during cardiac surgery. DESIGN: An observational prospective cohort with propensity score analysis. SETTING: At a tertiary academic hospital's operating room and intensive care unit (ICU)...

The prevalence of valvular heart disease in the United States has been estimated at 4.2-to-5.6 million, with mitral regurgitation (MR) being the most common lesion. Significant MR is associated with heart failure (HF) and death if left untreated. When HF is present, renal dysfunction (RD) is common and is associated with worse outcomes (ie, it is a marker of HF disease progression). Additionally, a complex interplay exists in patients with HF who also have MR, as this combination further impairs renal function, and the presence of RD further worsens prognosis and often limits guideline-directed management and therapy (GDMT)...

THIS SPECIAL article is part of an annual series for the Journal of Cardiothoracic and Vascular Anesthesia. The authors thank the editor-in-chief, Dr. Kaplan, and the Editorial Board for the opportunity to continue this series, which focuses on the past year's research highlights that pertain to perioperative echocardiography in relation to cardiothoracic and vascular anesthesia. The major selected themes for 2022 include (1) updates on mitral valve assessments and interventions, (2) training and simulation updates, (3) outcomes and complications of transesophageal echocardiography, and (4) point-of-care cardiac ultrasound...

OBJECTIVES: Surgery for pleural empyema carries a high burden of morbidity and mortality. The authors investigated the incidence of postoperative pulmonary complications (PPCs) and their effects on perioperative morbidity and mortality. Patient-specific, preoperative, procedural, and postoperative risk factors for PPCs were analyzed. DESIGN: Retrospective observational study. SETTING: A single, large university hospital. PARTICIPANTS: A total of 250 adult patients were included who underwent thoracic surgery for pleural empyema between January 2017 and December 2021...

OBJECTIVES: To clarify the influence of lower tidal volume (4-7 mL/kg) compared with higher tidal volume (8-15 mL/kg) during one-lung ventilation (OLV) on gas exchange and postoperative clinical outcome. DESIGN: Meta-analysis of randomized trials. SETTING: Thoracic surgery. PARTICIPANTS: Patients receiving OLV. INTERVENTIONS: Lower tidal volume during OLV. MEASUREMENTS AND MAIN RESULTS: Primary outcome was PaO2 - to-the oxygen fraction (PaO2 /FIO2 ) ratio at the end of the surgery, after the reinstitution of two-lung ventilation...

The objective of this systematic review was to evaluate the current evidence on the utility of preoperative B-type natriuretic peptide (BNP) and N-terminal-pro B-type natriuretic peptide (NT-proBNP) in predicting short-term and long-term mortality after coronary artery bypass grafting (CABG). OVID MEDLINE, EMBASE, SCOPUS, and PUBMED were searched from 1946 to August 2022 using the following terms: "coronary artery bypass grafting" and "BNP" and "outcomes." Eligible studies included observational studies reporting the association between preoperative BNP and NT-proBNP levels and short- and long-term mortality after CABG...

OBJECTIVE: The ProCCard study tested whether combining several cardioprotective interventions would reduce the myocardial and other biological and clinical damage in patients undergoing cardiac surgery. DESIGN: Prospective, randomized, controlled trial. SETTING: Multicenter tertiary care hospitals. PARTICIPANTS: 210 patients scheduled to undergo aortic valve surgery. INTERVENTIONS: A control group (standard of care) was compared to a treated group combining five perioperative cardioprotective techniques: anesthesia with sevoflurane, remote ischemic preconditioning, close intraoperative blood glucose control, moderate respiratory acidosis (pH 7...

OBJECTIVE: Little is known about changes in portal, splenic, and hepatic vein flow patterns in children undergoing congenital heart surgery. This study aimed to determine the characteristics of portal, splenic, and hepatic vein flow patterns using ultrasonography in children undergoing cardiac surgery. DESIGN: Single-center, prospective observational study. SETTING: Tertiary children's hospital, operating room. PARTICIPANTS: Children undergoing cardiac surgery...

OBJECTIVE: Stroke remains a devastating complication after cardiac surgical procedures despite perioperative monitoring and management advances. This study aimed to determine the predictors of stroke in a large, contemporary coronary artery surgery population. DESIGN: Patient data were analyzed retrospectively. SETTING: This single-center study was performed in the Catharina Hospital (Eindhoven). PARTICIPANTS: All patients who underwent isolated coronary artery bypass grafting (CABG) between January 1998 and February 2019 were included...
