With stress echo (SE) 2020 study, a new standard of practice in stress imaging was developed and disseminated: the ABCDE protocol for functional testing within and beyond CAD. ABCDE protocol was the fruit of SE 2020, and is the seed of SE 2030, which is articulated in 12 projects: 1-SE in coronary artery disease (SECAD); 2-SE in diastolic heart failure (SEDIA); 3-SE in hypertrophic cardiomyopathy (SEHCA); 4-SE post-chest radiotherapy and chemotherapy (SERA); 5-Artificial intelligence SE evaluation (AI-SEE); 6-Environmental stress echocardiography and air pollution (ESTER); 7-SE in repaired Tetralogy of Fallot (SETOF); 8-SE in post-COVID-19 (SECOV); 9: Recovery by stress echo of conventionally unfit donor good hearts (RESURGE); 10-SE for mitral ischemic regurgitation (SEMIR); 11-SE in valvular heart disease (SEVA); 12-SE for coronary vasospasm (SESPASM). The study aims to recruit in the next 5 years (2021–2025) ≥10,000 patients followed for ≥5 years (up to 2030) from ≥20 quality-controlled laboratories from ≥10 countries. In this COVID-19 era of sustainable health care delivery, SE2030 will provide the evidence to finally recommend SE as the optimal and versatile imaging modality for functional testing anywhere, any time, and in any patient.

Background: Resting coronary flow velocity (CFV) in the mid‐distal left anterior descending coronary artery can be easily assessed with transthoracic echocardiography. In this observational study, the authors sought to assess the relationship between resting CFV, CFV reserve (CFVR), and outcome in patients with chronic coronary syndromes. Methods and Results: In a prospective multicenter study design, the authors retrospectively analyzed 7576 patients (age, 66±11 years; 4312 men) with chronic coronary syndromes and left ventricular ejection fraction ≥50% referred for dipyridamole stress echocardiography. Recruitment (years 2003–2021) involved 7 accredited laboratories, with interobserver variability <10% for CFV measurement at study entry. Baseline peak diastolic CFV was obtained by pulsed‐wave Doppler in the mid‐distal left anterior descending coronary artery. CFVR (abnormal value ≤2.0) was assessed with dipyridamole. All‐cause death was the only end point. The mean CFV of the left anterior descending coronary artery was 31±12 cm/s. The mean CFVR was 2.32±0.60. During a median follow‐up of 5.9±4.3 years, 1121 (15%) patients died. At multivariable analysis, resting CFV ≥32 cm/s was identified by a receiver operating curve as the best cutoff and was independently associated with mortality (hazard ratio [HR], 1.24 [95% CI, 1.10–1.40]; P <0.0001) together with CFVR ≤2.0 (HR, 1.78 [95% CI, 1.57–2.02]; P <0.0001), age, diabetes, history of coronary surgery, and left ventricular ejection fraction. When both CFV and CFVR were considered, the mortality rate was highest in patients with resting CFV ≥32 cm/s and CFVR ≤2.0 and lowest in patients with resting CFV 2.0. Conclusions: High resting CFV is associated with worse survival in patients with chronic coronary syndromes and left ventricular ejection fraction ≥50%. The value is independent and additive to CFVR. The combination of high resting CFV and low CFVR is associated with the worst survival.

Stress echo (SE) 2030 study is an international, prospective, multicenter cohort study that will include >10,000 patients from ≥20 centers from ≥10 countries. It represents the logical and chronological continuation of the SE 2020 study, which developed, validated, and disseminated the “ABCDE protocol” of SE, more suitable than conventional SE to describe the complex vulnerabilities of the contemporary patient within and beyond coronary artery disease. SE2030 was started with a recruitment plan from 2021 to 2025 (and follow-up to 2030) with 12 subprojects (ranging from coronary artery disease to valvular and post-COVID-19 patients). With these features, the study poses particular challenges on quality control assurance, methodological harmonization, and data management. One of the significant upgrades of SE2030 compared to SE2020 was developing and implementing a Research Electronic Data Capture (REDCap)-based infrastructure for interactive and entirely web-based data management to integrate and optimize reproducible clinical research data. The purposes of our paper were: first, to describe the methodology used for quality control of imaging data, and second, to present the informatic infrastructure developed on RedCap platform for data entry, storage, and management in a large-scale multicenter study.

Background: Outcome of Mitral Valve Prolapse (MVP) was controversial for long time. Many studies reported great differences in the incidence of cardiovascular events due, above all, to heterogeneous and small studied populations. Most of theme were also published to late ’80 of the last century till early ’00. Purpose: To make a contemporary survey on the incidence of cardiovascular events in a selected population of patients affected by primary MVP referred to a tertiary cardiovascular center for the medical and surgical care of valvular heart disease. Methods: We reviewed our MVP database; patients with at least 2 cardiologic evaluations inclusive of echocardiographic examination and at least 6 months follow up were enrolled. A total of 250 patients (126 F) were selected. Their mean age was 52.1 years (ranging from 13 to 88 yo). The average follow-up time was 100 months (8,33 yrs). Results: At the first medical and echocardiographic examination 8 patients (3,2%) had no mitral regurgitation (MR), 104 (41.6%) have a trace/mild MR, 93 (37,2%) a moderate MR and 46 (18,4%) a severe MR. They were widely asymptomatic (NYHA I 205-82%, NYHA II 44-17.60%, NYHA III 1- 0.40%). Most of theme presented a bileaflet (140-55.8%) or a posterior MVP (94 - 37.6%); an isolated anterior MVP was rare (16 – 6,4%). Flail leaflet was present in 8 (3,2%) and 25 (10%) had a chordal rupture. Respectively 165 (65,6%) and 115 (46,1%) patients had thick and redundant leaflets. Mean antero-posterior mitral annulus diameter was 37 mm. During the follow up 7 patients died of non-cardiac cause and 5 (2%) of suspected cardiac cause (2 because of acute coronary syndrome and 3 died suddenly). MR progresses in 43 (17,2%) patients and finally we observed 81 (32,4%) moderate/severe and severe MR. 12 new chordal rupture occurred during the follow up in most cases concerning mitral chordae linked to posterior mitral leaflet (10 cases-83,3%). The worsening of MR provoked an evolution of the clinical condition of 48 patients (19.2%) which developed Dyspnea On Excertion (DOE) with 42 new NYHA II and 6 new NYHA III. At the end of the follow up the amount of patients symptomatic for DOE was 93 (37.2% vs 18% at the initial evaluation). A total of 45 patients (18%) underwent mitral valve surgery. 40 needed in-hospital treatment in most cases due to the development of atrial fibrillation (19 -7.6%) or heart failure ( 8- 3,2%). Endocarditis occurred in 4 patients (1.6%) and cerebrovascular accidents/cardioembolic event in 6 (2.4%). The overall cardiovascular event rate was 4,33/100 patients-year, significantly higher than reported in community based studies. Conclusions: The prognosis of a MVP population referred to a tertiary cardiovascular center is not benign. The most frequent complications are progression of MR and MV surgery. Sudden death is also more frequent than in general population. More studies are needed to identify what patients with MVP are at risk for it.

Postgraduate training programmes allow matriculation in formalised ACHD fellowships from multiple training pathways. In the UK, 2-year ACHD subspecialty training blocks are offered to physicians with a national training number in adult or paediatric cardiology, supplemented by locally arranged, informal fellowship posts. A shorter period of ACHD training can be combined with another subspecialty, such as advanced imaging, for those aiming to work as a cardiologist with …

The objective of this study was to assess left ventricle (LV) function in patients underwent arterial switch procedure (ASO) for transposition of great arteries (TGA) in long-term follow-up. We studied 59 asymptomatic patients (43 male) who have undergone single-stage ASO for TGA, aged 13.9 ± 4.8 years, with a normal LV ejection fraction, compared to healthy peers. We evaluated LV volume, function and myocardial deformation in asymptomatic patients with normal ejection fraction by using speckle-tracking echocardiography (STE). Global longitudinal strain (GLS) was lower in patients compared to healthy peers throughout all age groups (5–9 years: −20.03 ± 0.65% vs 21.00 ± 1.30%, p = 0.083; 10–14 years: −19.43 ± 1.75% vs −21.80 ± 1.30%, p < 0.0001; 15–19 years: −19.05 ± 1.65% vs −22.50 ± 1.30%, p < 0.0001; 20–24 years: −17.90 ± 0.85% vs −20.90 ± 1.30%, p < 0.0001; >25 years: −18.60 ± 0.42% vs 20.60 ± 1.20%, p = 0.041). At the univariate analysis GLS resulted significantly related only to the presence of restrictive patent foramen ovale at birth (p = 0.0016). At the multivariate analysis GLS was significantly related to prenatal diagnosis, restrictive patent foramen ovale and by-pass time. Children and young adults late after ASO demonstrate normal ejection fraction, but present subclinical signs of myocardial dysfunction, such as reduction of longitudinal strain. Our findings support the usefulness of STE to detect it precociously.
