Cardiac Ultrasound Training for Medical Students Utilizing Drawing and Ward-Based Instruction.

Introduction: In this report, we present a cardiac ultrasound training module for medical student learners. The module assists medical students in developing foundational skills in image acquisition, identification of normal cardiac ultrasound anatomy, and demonstration of professionalism when performing the associated OSCE exam.

Methods: We delivered the module across a 2-week cardiology rotation.

Echocardiographic Screening for Rheumatic Heart Disease: A Brief History and Implications for the Future.

Transthoracic echocardiography is the gold standard for early detection of rheumatic heart disease (RHD) in asymptomatic children living in high-risk regions. Advances in technology allowing miniaturisation and increased portability of echocardiography devices have improved the accessibility of this vital diagnostic tool in RHD-endemic locations. Automation of image optimisation techniques and simplified RHD screening protocols permit use by non-experts after a brief period of training.

Use of an ultrasound picture archiving and communication system to answer research questions: Description of data cleaning methods.

Introduction/purpose: Ultrasound picture archiving and communication system (PACS) databases are useful for quality improvement and clinical research but frequently contain free text that is not easily readable. Here, we present a method to extract and clean a semi-structured echocardiography (cardiac ultrasound) PACS database.

Methods: Echocardiography studies between 1 January 2010 and 31 December 2018 were extracted using a data mining tool.

Image quality and technical limitations in emergency department cardiac point-of-care ultrasound: A retrospective cohort study.

Objective: To assess the image quality and common technical limitations seen on cardiac point-of-care ultrasound (POCUS) performed and archived in a single New Zealand ED.

Methods: A retrospective cohort study of clinically indicated cardiac POCUS, archived from 1 October 2019 to 20 May 2020. Archived examinations were retrospectively reviewed by an ED POCUS expert, and an expert cardiac sonographer to determine diagnostic image quality, technical limitations present and opportunities for image quality improvement.

Ethnicity Is Associated With Differing Presentation and Outcomes of Patients Undergoing Aortic Valve Replacement for Calcific Aortic Stenosis in Aotearoa New Zealand.

Aim: Surgical aortic valve replacement (SAVR) has been the gold standard for treatment of severe symptomatic aortic stenosis (AS) for decades. We examined whether ethnic differences exist in the presentation and outcomes of patients undergoing aortic valve replacement (AVR) for AS in New Zealand.

Methods: Patients of New Zealand European, Māori, and Pacific Island ethnicities undergoing SAVR with or without other procedures in New Zealand public hospitals from 2017 to 2019 were included.

Outcomes of patients with early calcific aortic valve disease detected by clinically indicated echocardiography.

Aims: Previous studies have demonstrated relatively slow rates of progression of early calcific aortic valve disease (CAVD), which encompasses aortic sclerosis (ASc) and mild aortic stenosis (AS). The potential evolution to clinically significant AS is unclear, and we therefore examined the long-term outcomes of patients with ASc and mild AS detected at the time of clinically indicated echocardiography.

Methods And Results: Data from initial clinically indicated echocardiograms performed between 2010 and 2018 in patients aged ≥18 years were extracted and linked to nationally collected outcome data.

Survey of echocardiography practice across five continents.

Background And Aim: The term echocardiography refers to a diverse range of cardiovascular ultrasound imaging methods, both inside and outside specialist cardiology practice. While guidelines exist, we hypothesized that there are significant worldwide differences in the way echocardiography is practiced. We surveyed echocardiography practitioners around the world to characterize the workforce and their practice.

Abbreviated Echocardiographic Screening for Rheumatic Heart Disease by Nonexperts with and without Offsite Expert Review: A Diagnostic Accuracy Study.

Background: Early detection of rheumatic heart disease (RHD) through echocardiographic screening can facilitate early access to effective treatment, which reduces the risk for progression. Accurate, feasible approaches to echocardiographic screening that can be incorporated into routine health services are needed. The authors hypothesized that offsite expert review could improve the diagnostic accuracy of nonexpert-obtained echocardiographic images.

Adjunct Methods for the Detection of Patent Foramen Ovale: The Contribution of Transcranial Doppler and the Valsalva Manoeuvre.

A patent foramen ovale (PFO) is present in 25% of the population. In some patients, especially those without traditional stroke risk factors and with no immediately apparent cause, a cryptogenic stroke may be caused by an embolus passing through the PFO to the systemic circulation. The identification, or indeed exclusion, of a PFO is sought in these patients, most commonly using contrast-enhanced transthoracic or transoesophageal echocardiography.

New Echocardiography Reference Ranges for Aotearoa (NewERA) Study: the application of international echocardiographic reference values to linear measurements of the hearts of healthy, young Māori and Pacific adults may not detect cardiac enlargement.

Aims: To develop ethnic-specific echocardiography reference ranges for Aotearoa, and to investigate the impact of indexation to body surface area (BSA). Current reference international ranges are derived from people of mostly NZ European ethnicity and may not be appropriate for Māori and New Zealanders of Pacific ethnicity, who both experience high rates of cardiovascular disease.

Methods: Echocardiography was performed in a cross-sectional study of 263 healthy adults (18-50 years): Māori (N=71, 43 female), Pacific (N=53, 28 female), European (N=139, 74 female).

Estimating heart mass from heart volume as measured from post-mortem computed tomography.

Heart mass can be predicted from heart volume as measured from post-mortem computed tomography (PMCT), but with limited accuracy. Although related to heart mass, age, sex, and body dimensions have not been included in previous studies using heart volume to estimate heart mass. This study aimed to determine whether heart mass estimation can be improved when age, sex, and body dimensions are used as well as heart volume.
