Strain estimation in aortic roots from 4D echocardiographic images using medial modeling and deformable registration.

Even though the central role of mechanics in the cardiovascular system is widely recognized, estimating mechanical deformation and strains in-vivo remains an ongoing practical challenge. Herein, we present a semi-automated framework to estimate strains from four-dimensional (4D) echocardiographic images and apply it to the aortic roots of patients with normal trileaflet aortic valves (TAV) and congenital bicuspid aortic valves (BAV). The method is based on fully nonlinear shell-based kinematics, which divides the strains into in-plane (shear and dilatational) and out-of-plane components.

The Year in Graduate Medical Education: Selected Highlights From 2021.

This special article is the first in a planned annual series for the Journal of Cardiothoracic and Vascular Anesthesia that will highlight significant literature from the world of graduate medical education (GME) that was published over the past year. The major themes selected for this inaugural review are the educational value of simulation and training workshops, the expanding role of social media and other information technologies in GME and recruitment, the state of residency and fellowship training before the COVID-19 pandemic, and the inevitable effects COVID-19 has had on graduate medical education. The authors would like to thank the editorial board for allowing us to shine a light on a small subset of the writing and research produced in this field, so that educators may understand how best to educate and train the next generation of anesthesiologists.

The authors thank the editor-in-chief, Dr Kaplan, and the editorial board for the opportunity to continue this series; namely, the research highlights of the past year in the specialty of cardiothoracic and vascular anesthesiology. The major themes selected for 2020 are outlined in this introduction, and each highlight is reviewed in detail in the main body of the article.

Pilot Study Suggests Smartphone Application Knowledge Improves Resident Transesophageal Echocardiography Knowledge: A Randomized Controlled Trial.

Objective: The objective of this study was to determine whether an asynchronous smartphone-based application with image-based questions would improve anesthesiology resident transesophageal echocardiography (TEE) knowledge compared with standard intraoperative teaching alone.

Design: Prospective, single-blinded, pilot, randomized controlled trial.

Setting: Large university teaching hospital.

The Program Evaluation Committee in the Adult Cardiothoracic Anesthesiology Fellowship - Harnessing Opportunities for Program Improvement.

The Program Evaluation Committee has an essential role in the quality improvement process of the adult cardiothoracic anesthesiology fellowship. The annual program evaluation presents all stakeholders with an opportunity to evolve with the changing needs and opportunities of the fellowship milieu. The active engagement of the program in this process is a high-quality approach to successful planning, preparation and conduct of the self-study and site visit that are important extensions of the annual program evaluation and the program evaluation committee.

Clinical update in liver transplantation.

There has been considerable recent progress liver transplantation (LTX). The postreperfusion syndrome has clearly defined and typically responds to vasopressin and/or methylene blue when refractory to catecholamine therapy. Diastolic dysfunction and cirrhotic cardiomyopathy are prevalent and important in LTX recipients.

Preoperative cardiac risk assessment for noncardiac surgery: defining costs and risks.

Cardiac risk stratification before noncardiac surgery remains important. Two major areas have been emphaized, namely, cost-effective risk stratification and enhanced identification of high risk populations. Recent studies have highlighted the lack of quality and affordable medical consultation.

Leukotoxin confers beta-hemolytic activity to Actinobacillus actinomycetemcomitans.

Actinobacillus actinomycetemcomitans is the etiologic agent of localized aggressive periodontitis, a rapidly progressing oral disease that occurs in adolescents. A. actinomycetemcomitans can also cause systemic disease, including infective endocarditis.

Characterization of leukotoxin from a clinical strain of Actinobacillus actinomycetemcomitans.

Actinobacillus actinomycetemcomitans is a Gram negative pathogen that is the etiologic agent of localized aggressive periodontitis (LAP), a rapidly progressing and severe disease of the oral cavity that affects predominantly adolescents. A. actinomycetemcomitans is also found in extraoral infections including infective endocarditis.
