- The new manual on indications for and performance of echocardiography focuses primarily on the transthoracic echocardiographic approach. The performance of a standardized documentation in transthoracic echocardiography includes the acquisition of several cineloops and Doppler spectra with consecutive measurements illustrated by figures and a scheme of an echocardiographic report. The extended documentation in transthoracic echocardiography is presented with respect to specific pathological alterations of the heart. This includes alterations of the left ventricular wall thickness, the global and regional reduction of left ventricular function, diastolic dysfunction with normal left ventricular systolic function, pressure and volume overload of the right ventricle and the reduction of right ventricular function and pathological alterations of the heart valves. Echocardiography performed in the presence of aortic valve stenosis and regurgitation, mitral valve stenosis and regurgitation, tricuspid valve regurgitation as well as less common heart valve diseases and endocarditis is presented in special sections. The manual ends with sections describing additional echocardiographic modalities, the reporting and the use of emergency echocardiography.

- The second manual on indications for and performance of echocardiography focusses on specific echocardiographic modalities and special problems in several patient cohorts. Practical aspects are discussed with priority. Established echocardiographic modalities are transesophageal, stress and contrast echocardiography. Modern technologies, such as 3D echocardiography and deformation imaging play an important role in nearly all scenarios of clinical echocardiography. This complete echocardiographic spectrum is incorporated into emergency and intensive care medicine, monitoring interventions of structural heart diseases, cardiac surgery, patients with cardiac assist devices, adult patients with congenital heart diseases and the care of highly infectious patients in pandemics. The diagnostic procedures of conventional and modern echocardiography are highlighted in this manual. The use of 3D echocardiography to characterize cardiac morphology and the application of deformation imaging to objectify cardiac function are already established in clinical practice. Stress echocardiography to detect myocardial ischemia and viability or to diagnose valvular heart diseases, assessment of coronary flow reserve to analyze myocardial perfusion and contrast echocardiography for left ventricular opacification and tumor characterization are increasingly being used to improve diagnostics. As mentioned for conventional echocardiography in the last manual of echocardiography in 2009, the modern features in echocardiography require standardized documentation and acquisition of certain images with optimized ultrasound settings, because conclusive and reproducible data analysis can only be performed if the image quality is sufficient.

- Aims This European Association Cardiovascular Imaging (EACVI) Expert Consensus document aims at defining the main quantitative information on cardiac structure and function that needs to be included in standard echocardiographic report following recent ASE/EACVI chamber quantification, diastolic function, and heart valve disease recommendations. The document focuses on general reporting and specific pathological conditions such as heart failure, coronary artery and valvular heart disease, cardiomyopathies, and systemic diseases. Methods and results Demographic data (age, body surface area, blood pressure, and heart rhythm and rate), type (vendor and model) of ultrasound system used and image quality need to be reported. In addition, measurements should be normalized for body size. Reference normal values, derived by ASE/EACVI recommendations, shall always be reported to differentiate normal from pathological conditions. This Expert Consensus document suggests avoiding the surveillance of specific variable using different ultrasound techniques (e.g. in echo labs with high expertise in left ventricular ejection fraction by 3D and not by 2D echocardiography). The report should be also tailored in relation with different cardiac pathologies, quality of images, and needs of the caregivers. Conclusion The conclusion should be concise reflecting the status of left ventricular structure and function, the presence of left atrial and/or aortic dilation, right ventricular dysfunction, and pulmonary hypertension, leading to an objective communication with the patient health caregiver. Variation over time should be considered carefully, taking always into account the consistency of the parameters used for comparison.

- This paper documents how an ethically aligned co-design methodology ensures trustworthiness in the early design phase of an artificial intelligence (AI) system component for healthcare. The system explains decisions made by deep learning networks analyzing images of skin lesions. The co-design of trustworthy AI developed here used a holistic approach rather than a static ethical checklist and required a multidisciplinary team of experts working with the AI designers and their managers. Ethical, legal, and technical issues potentially arising from the future use of the AI system were investigated. This paper is a first report on co-designing in the early design phase. Our results can also serve as guidance for other early-phase AI-similar tool developments.
