“…However, akin to 3DE-LV, a lack of contemporaneous normative reference values for 3DE-RV volumes and EF breaking into societal guidelines was again highlighted as a potential barrier [ 21 ]. Interestingly, societal guidelines recommend that global RV function should be evaluated [ 1 , 22 , 23 ], and this remains largely carried out through the application of RV FAC% over 3DE-RV, which was indicated in our UK survey data and likely reflects the BSE minimal dataset requirements [ 3 ].…”

“…Quantification of left ventricular (LV) and right ventricular (RV) size and function is a key component to all transthoracic echocardiography (TTE) examinations [ 1 , 2 ]. The introduction of three-dimensional echocardiography (3DE) has permitted advancements in the quantification of LV and RV volumes and ejection fraction (EF), all without the impact of geometric chamber assumptions, regional variations in contractility or passive cardiac motion [ 3 , 4 ]. It is also the only echocardiographic modality allowing for direct measurement of RV volumes and EF without the need for surrogate linear markers of RV contractility.…”

Three-dimensional echocardiography (3DE) imaging has permitted advancements in the quantification of left ventricular (LV) and right ventricular (RV) volumes and ejection fraction. We evaluated the availability of 3DE equipment / analysis software, the integration of 3DE assessment of the LV and RV in routine clinical practice, current training provisions in 3DE, and aimed to ascertain barriers preventing the routine use of 3DE for volumetric analysis. Through the British Society of Echocardiography (BSE) regional representatives’ network, echocardiographers were invited to participate in an open online survey. A total of 181 participants from echocardiography departments in the United Kingdom (UK), the majority from tertiary centres (61%), completed the 28-question survey. For 3DE quantification, 3DE-LV was adopted more frequently than 3DE-RV (48% vs 11%, respectively). Imaging feasibility was a recognised factor in 3DE RV and LV adoption. Many respondents had access to 3D probes (93%). The largest observed barriers to 3DE routine use were training deficiencies, with 83% reporting they would benefit from additional training opportunities and the duration of time permitted for the scan, with 68% of responders reporting allowances of less than the BSE standard of 45–60 min per patient (8% < 30-min). Furthermore, of those respondents who had undertaken professional accreditation, competence in 3DE was not formally assessed in 89%. This UK survey also reported good accessibility to magnetic resonance imaging (72%), which was related to overall 3DE adoption. In summary, although 3DE is now readily available, it remains underutilised. Further training opportunities, integrated formal assessment, improved adoption of BSE minimum recommended scanning times, alongside industry and societal support, may increase 3DE utilisation in routine practice.

“…Indeed, sonographers and cardiologists must be educated in image capture and analysis techniques that allow for reliable post-processing and robust results, but integrating AEI requires many other crucial resources, such as suitable equipment, patient selection, adoption of protocols into ordinary clinical practice, modification of echo lab workflow, storage, and reporting. 29 In addition, hospital administration must acknowledge and believe in the clinical usefulness of AEI and necessary billing and reimbursement adaptations, as AEI also involves a discussion around cost justification. It’s also essential to define more robust reference values and standardization of values, considering that 66% of centres in the present survey use two or more different vendors within the same laboratory.…”

Aims Advanced echocardiographic imaging (AEI) techniques, such as three-dimensional (3D) and multi-chamber speckle-tracking deformation imaging (strain) analysis, have been shown to be more accurate in assessing heart chamber geometry and function when compared with conventional echocardiography providing additional prognostic value. However, incorporating AEI alongside standard examinations may be heterogeneous between echo laboratories (echo labs). Thus, our goal was to gain a better understanding of the many AEI modalities that are available and employed in Italy. Methods and results The Italian Society of Echocardiography and Cardiovascular Imaging (SIECVI) conducted a national survey over a month (November 2022) to describe the use of AEI in Italy. Data were retrieved via an electronic survey based on a structured questionnaire uploaded on the SIECVI website. Data obtained from 173 echo labs were divided into 3 groups, according to the numbers of echocardiograms performed: <250 exams (low-volume activity, 53 centres), between 251 and 550 exams (moderate-volume activity, 62 centres), and ≥550 exams (high-volume activity, 58 centres). Transthoracic echocardiography (TTE) 3D was in use in 75% of centres with a consistent difference between low (55%), medium (71%), and high activity volume (85%) (P = 0.002), while 3D transoesophageal echocardiography (TEE) was in use in 84% of centres, reaching the 95% in high activity volume echo labs (P = 0.006). In centres with available 3D TTE, it was used for the left ventricle (LV) analysis in 67%, for the right ventricle (RV) in 45%, and for the left atrium (LA) in 40%, showing greater use in high-volume centres compared with low- and medium-volume centres (all P < 0.04). Strain analysis was utilized in most echo labs (80%), with a trend towards greater use in high-volume centres than low- and medium-volume centres (77%, 74%, and 90%, respectively; P = 0.08). In centres with available strain analysis, it was mainly employed for the LV (80%) and much less frequently for the RV and LA (49% and 48%, respectively). Conclusion In Italy, the AEI modalities are more frequently available in centres with high-volume activity but employed only in a few applications, being more frequent in analysing the LV compared with the RV and LA. Therefore, the echocardiography community and SIECVI should promote uniformity and effective training across the Italian centres. Meanwhile, collaborations across centres with various resources and expertise should be encouraged to use the benefits of the AEI.
