Observational StudyQuantification of Right Atrial-Indexed End-Systolic Volumes and Emptying Fraction in Children Undergoing Cardiac Surgery With Two-Dimensional Transesophageal Echocardiography: A Prospective Observational Study.
The primary objective of this study was to establish "normal" right atrial (RA)-indexed end-systolic volumes (ESVs) and emptying fraction (EF) in children undergoing ventricular septal defect (VSD) repair using two-dimensional (2D) transesophageal echocardiography (TEE). Secondary objectives were to obtain RA-indexed ESV and EF in children with RA/right ventricular (RV) volume overload (atrial septal defect [ASD]) and RV pressure overload (tetralogy of Fallot [TOF]) and to determine whether baseline differences existed in these indices among the three lesions. ⋯ This was the first study using 2D TEE to measure RA indices in children with and without right-sided heart dilation undergoing cardiac surgery. In this study, RA, ESV, and EF were considerably different in children with congenital heart disease causing RV pressure or volume overload. Additional studies can examine how these values can be used for risk stratification in this cohort of patients or how they correlate with measures of ventricular performances.

Editorial CommentScore2: A New Updated Algorithm to Predict Cardiovascular Disease Risk in Europe.
The recently published guidelines of the European Society of Cardiology for the prevention of cardiovascular diseases presented in August 2021 at the virtual European Society of Cardiology congress recommend the use of the SCORE2 risk index instead of the classic SCORE risk index to calculate the cardiovascular risk (specifically, ten-year fatal and nonfatal risk) in a healthy population under the age of 70 years, with a level of evidence IB. This new risk index was developed with the collaboration of about 200 investigators, including 45 cohorts in 13 countries with 700,000 participants, and covers the known risk factors for heart and circulatory diseases such as age, sex, lipid levels, blood pressure, and smoking. In addition, it divides the countries into four groups of risk and uses a competing risk model, adjusting the risk for the probability of having another event, which enables better estimation of the risk of fatal and nonfatal events in a younger population (40-69 years).

In this E-Challenge, the authors report on a patient with symptoms of exertional dyspnea and angina, scheduled to have surgical unroofing of an identified myocardial bridge (MB). An MB is very common in patients with hypertrophic cardiomyopathy (HCM). ⋯ HCM has many phenotypic variants that can make the identification of patients with latent left ventricular outflow tract obstruction difficult in the absence of a high index of suspicion. In this report, the authors discuss the association between MBs and HCM and the importance of recognizing phenotypic variants of HCM.

Preliminary Study of Serum Biomarkers Associated With Delirium After Major Cardiac Surgery.
The objective of this study was to identify novel serum biomarkers specific to postoperative delirium after major cardiac surgery to provide insight into the pathologic processes involved in delirium and its sequelae. ⋯ FGF-21, FGF-23, interleukin-6, and monocyte chemotactic protein-3 serum levels were increased postoperatively in patients who developed delirium after major cardiac surgery. This study identified two members of the FGF family as potential putative systemic biomarkers for postoperative delirium after cardiac surgery, suggesting a possible role for metabolic recovery in the pathophysiologic mechanisms underlying neurocognitive dysfunction.

Case ReportsFactor V Deficiency (Owren's Disease) in a Patient at High Risk for Transfusion-Associated Circulatory Overload and Bleeding During Laser Lead Extraction.
Congenital factor V deficiency is an extremely rare abnormality and may be associated with significant bleeding as a result of trauma or surgery. Perioperative management primarily includes the administration of fresh frozen plasma to replace the deficient clotting factor. Acute administration of multiple blood products is a risk factor for transfusion-associated circulatory overload. Herein, the case of a 71-year-old man with an ejection fraction of 13% and a history of congenital factor V deficiency who was at risk for significant bleeding and transfusion-associated circulatory overload who underwent successful complex extraction of a right atrial pacing lead is reported.
