Purpose: Because the training that noncardiologists require to perform cardiac hand-carried ultrasound has not been defined, we studied how well hospitalists perform hand-carried echocardiography after limited training.
Methods: Ten hospitalists completed a focused training program that included performing an average of 35 hand-carried echocardiograms. Hospitalists' echocardiograms were compared with gold-standard conventional echocardiograms, and hospitalists were compared with 5 certified echocardiography technicians in their ability to acquire, measure, and interpret hand-carried ultrasound images and with 6 senior cardiology fellows in their ability to interpret echocardiograms.
Results: Echocardiography technicians had significantly higher performance scores for image acquisition, measurement, and interpretation than hospitalists. Senior cardiology fellows outperformed hospitalists in most aspects of image interpretation. For hospitalists, learning image acquisition was more difficult than image interpretation.
Conclusions: Hospitalists can learn aspects of hand-carried echocardiography, but after 35 training echocardiograms cannot replicate the quality of conventional echocardiography. Whether the lower performance skills are important will depend on the clinical context of hand-carried echocardiography performed by hospitalists.

Background: The World Heart Federation (WHF) published the first evidence-based guidelines on the echocardiographic diagnosis of rheumatic heart disease (RHD) in 2012. These guidelines have since been applied internationally in research and clinical practice. Substantial research has assessed the utility of the 2012 WHF criteria, including its applicability in low-resource settings.

Background: Machine learning (ML) algorithms can accurately estimate left ventricular ejection fraction (LVEF) from echocardiography, but their performance on cardiac point-of-care ultrasound (POCUS) is not well understood.
Objectives: We evaluate the performance of an ML model for estimation of LVEF on cardiac POCUS compared with Level III echocardiographers' interpretation and formal echo reported LVEF.
Methods: Clinicians at a tertiary care heart failure clinic prospectively scanned 138 participants using hand-carried devices.

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.

Background: Focused cardiac ultrasound examination (FoCUS) is rapidly emerging for point-of-care cardiac assessment using hand-carried ultrasound (HCU) devices. A specific FoCUS protocol for horses and adequate training guidelines currently are not available.
Hypothesis: To gain knowledge about the training necessary to become proficient in performing FoCUS using a HCU device.

Internal derangement (ID) in the temporomandibular joint (TMJ) is defined as a mechanical problem of the joint that interferes with its function. It is attributed to an abnormal interaction among the articular disc, condyle, and joint eminence. The aim of this study is to evaluate diagnostic efficacy of non-invasive hand-carried ultrasonography instrumentation (US) to provide high-level images for a correct diagnosis of ID.
