Background Post-COVID-19 condition refers to a range of persisting physical and neurocognitive symptoms following SARS-CoV-2 infection. Recent evidence revealed that post-COVID syndrome patients may suffer from cardiac dysfunction and are at increased risk for a broad range of cardiovascular disorders. This randomized, sham-control, double-blind trial evaluated the effect of hyperbaric oxygen therapy (HBOT) on the cardiac function of post-COVID-19 patients with ongoing symptoms for at least three months after confirmed infection. Methods Sixty patients were randomized to receive 40 daily HBOT or sham sessions. They underwent echocardiography at baseline and 1-3 weeks after the last protocol session. Results Twenty-nine (48.3%) patients had reduced global longitudinal strain (GLS) at baseline. Of them, 13 (43.3%) and 16 (53.3%) were allocated to the sham and HBOT groups, respectively. Compared to the sham group, GLS significantly increased following HBOT (−17.8±1.1 to −20.2±1.0, p = 0.0001), with a significant group-by-time interaction (p = 0.041). Conclusion Post-COVID syndrome patients despite normal EF often have subclinical left ventricular dysfunction that is characterized by mildly reduced GLS. HBOT promotes left ventricular systolic function recovery in patients suffering from post COVID-19 condition. Further studies are needed to optimize patient selection and evaluate long-term outcomes.","PeriodicalId":11963,"journal":{"name":"European Journal of Echocardiography","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136161744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background Combined anatomical and functional imaging enables detection of non-obstructive and obstructive coronary artery disease (CAD) as well as myocardial ischemia, and also provides prognostic information. Purpose We evaluated sex differences in disease phenotype and adverse outcomes by using non-invasive combined anatomical and functional imaging in symptomatic patients with suspected CAD. Methods We retrospectively evaluated patients undergone coronary computed tomography angiography (CTA) for suspected CAD. According to local routine, patients with suspected obstructive stenosis on CTA were referred to downstream 15O-water positron emission tomography (PET) myocardial perfusion imaging to assess stress myocardial blood flow (MBF; ≤2.3 mL/g/min considered abnormal). A composite adverse endpoint was recorded, including all-cause death, myocardial infarction, and unstable angina pectoris. Results A total of 1948 patients (59% women) underwent coronary CTA of whom 657 (34%) patients underwent downstream PET perfusion imaging. During a mean follow-up of 6.8 years, 182 adverse events occurred. Women more often had normal coronary arteries (42% vs. 22%, p<0.001) and less often abnormal stress MBF (9% vs. 28%, p<0.001), as compared with men. The annual adverse event rate was lower in women versus men (1.2% vs. 1.7%, p = 0.02). Both in women and men, coronary calcification, non-obstructive CAD, and abnormal stress MBF were independent predictors of events. Abnormal stress MBF was associated with 5.0 and 5.6-fold adverse event rates in women and men, respectively. There was no statistical interaction between sex and coronary calcification, non-obstructive CAD, or abnormal stress MBF in terms of predicting adverse outcome. Conclusion Among patients evaluated for chronic chest pain, women have lower prevalence of ischemic CAD and lower rate of future adverse events. Combined coronary CTA and PET myocardial perfusion imaging predicts outcomes equally in women and men.","PeriodicalId":11963,"journal":{"name":"European Journal of Echocardiography","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136161745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background Spontaneous coronary artery dissection (SCAD) is one of the causes of acute coronary syndrome (ACS), myocardial infarction (MI) and sudden death (SD). Diagnosis is done with coronary angiography (CA); nevertheless, coronary computed tomography angiography (CCTA) is a new useful tool in the acute diagnosis and at follow-up. Treatment could involve a conservative approach or an invasive approach with percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). Purpose 1) analyze the clinical and CCTA features at baseline of patients with a SCAD diagnosis; 2) evaluate the clinical and anatomic outcome at follow-up of patients with a SCAD diagnosis treated with a conservative or invasive approach; 3) evaluate in the conservative approach treated patients the clinical and anatomic outcome of those dismissed with single or double antiplatelet therapy. Methods A retrospective analysis of 57 patients affected by SCAD followed up with Coronary CT angiography (CCTA) between 2010 and 2022. Clinical and anatomic data were collected at baseline and at the follow-up (FU). The clinical endpoints evaluated were: all cause mortality, hospitalization for cardiovascular cause, SCAD or PCI ex-novo and MI; the anatomic endpoints were: patency of coronary artery and/or stents and length dissection changing from baseline. Results 57 patients were divided in 2 groups: 46 (80,7%) patients underwent a conservative treatment and 11 (19,3%) patients a PCI treatment. Patients treated with PCI has a significative incidence of smokers (45,5% vs 15,2%; p = 0,042), peripherical arteriopathy (18,2% vs 0%; p = 0,034), higher troponin peak (40425,8 vs 13436; p = 0,011) and lower ejection fraction (51,4±11,0 vs 57,1±7,6; p = 0,050). Moreover the PCI population has a significant involvement of more than one coronary artery (72,7% vs 6,5%; p<0,001), of the proximal tracts of the coronary arteries (22,8% vs 13 %; p = 0,001) and of the truncus communis (45,4% vs 0%; p<0,001). At the follow up, there were no statistical differences for the clinical and anatomic endpoints between the conservative and invasive treated patients (p>0,05). Among patients treated with conservative therapy, there were a significant recurrence of SCAD in those treated with DAPT than in those treated with SAPT (33,3% vs 5,9%; p = 0,033). Conclusions patients with SCAD managed with PCI have more cardiovascular risk factors, a major myocardial infarction extension and a more complex coronary arteries involvement; conservative management is comparable to the PCI treatment for the clinical and anatomic endpoints evaluated; DAPT at discharge was associated with a higher rate of SCAD recurrence at follow-up.","PeriodicalId":11963,"journal":{"name":"European Journal of Echocardiography","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136161750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Main funding source(s): EACVI, Netherlands Heart Institute. Background MRI late gadolinium enhancement (LGE) images can provide novel insights about critical pathways through scar but does not assess the vulnerability of these pathways for sustaining scar-mediated ventricular tachycardia (VT). Computational modelling can augment the insights from imaging derived metrics by providing the functional implications of structural anatomy of the substrate. However, current (monodomain) approaches are computationally expensive and may not, by design, extract all critical pathways. Aim This study evaluated the performance of a novel, reaction-Eikonal based, automated reentrant pathway finding algorithm (VITA) to assess the functional viability of critical circuits identified on LGE and non-invasively predict arrhythmic risk in both an ICD and post-ablation cohort recurrence. Methods ADAS LV and custom-made software was used to generate 3D patient-specific ventricular models in a prospective cohort of post-infarct ICD patients (cohort 1, n=40) and a retrospective cohort of 20 post-infarct VT-ablation patients (cohort 2). Our Virtual Induction and Treatment of Arrhythmias (VITA) framework was then applied to comprehensively probe the viability of the scar substrate to sustaining reentrant circuits. VITA metrics, related to the numbers of induced VTs and their corresponding round trip times (RTTs), were compared with appropriate ICD therapy (cohort 1) and VT-recurrence (cohort 2) during follow-up. Results Patients in both cohorts with an event had higher VITA metrics. In cohort 1 (ICD), VITA demonstrated significantly more inducible VTs (6.6±4.2 vs. 4.1±3.4, p = .044), longer mean RTT (116.2±50.9 ms vs. 76.9±42.6 ms, p = .012) and max RTT (194.4±105.1 ms vs. 109.6±78.7, p =.009) in the event group. In addition, Cox-regression demonstrated a significant independent association with an event: induced VTs (HR 1.67; CI 1.04–2.68, p = .03), mean RTT (HR 2.14; CI 1.11–4.12, p = .02), maximum RTT (HR 2.13; CI 1.19–3.81, p = .01). In cohort 2 (VT-ablation), total induced VTs (85±43 vs. 42±27, p = .01) and unique VTs (9±4 vs. 5±4, p = .04) were significantly higher in patients with- compared to patients without recurrence, and were predictive of recurrence with AUC of .820 and .770, respectively. Max RTT demonstrated a trend towards significance 293 ± 90 ms vs. 200 ± 114 ms (p = .06) for recurrence and non-recurrence, respectively. No differences were observed in mean RTT between the two groups. Conclusion VITA enabled quantitative assessment of pro-arrhythmic vulnerability of the substrate which related directly to patient outcomes. The number of induced VTs were the most robust measure of appropriate ICD therapy and post-ablation arrhythmia recurrence. The RTT metrics, related to viable circuit lengths through scar, demonstrated a significant independent association with appropriate ICD therapy.","PeriodicalId":11963,"journal":{"name":"European Journal of Echocardiography","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136161576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background Left ventricular global circumferential strain using cardiovascular magnetic resonance (CMR) is an accurate indicator to predict cardiovascular events. Although several studies have shown the excellent prognostic value of stress CMR, the prognostic value of stress global circumferential strain (sGCS) remains unknown. Aim To investigate the prognostic value of sGCS for predicting cardiovascular events using a fully automatic machine learning algorithm without human correction in consecutive patients referred for stress CMR. Methods Between 2016 and 2018, all consecutive patients referred for stress CMR were included and followed for the occurrence of major adverse cardiovascular events (MACE), defined by cardiovascular death or nonfatal myocardial infarction (MI). A fully automatic machine learning algorithm was trained and validated on unseen CMR studies (MAGNETOM Aera and Skyra, Siemens Healthcare, Erlangen, Germany) to assess the sGCS from short-axis cine images at stress. The algorithm combines multiple deep learning networks for detection and segmentation with an active contours approach. Cox regressions were performed to determine the prognostic value of sGCS. Results Among 2,906 consecutive patients who underwent stress CMR, the automatic sGCS was successfully computed in 2,859 (98.4%) patients (68% male, mean age 64±12 years). A total of 256 (8.8%) MACEs were observed during a median (IQR) follow-up period of 4.5 (3.7–5.3) years. Using Kaplan-Meier analysis, sGCS and the presence of inducible ischemia were significantly associated with the occurrence of MACE (hazard ratio, HR: 1.12 [95% CI, 1.08–1.17]; and HR: 8.48 [95% CI, 6.05–11.91], both p<0.001; respectively). After adjustment for traditional risk factors, inducible ischemia and late gadolinium enhancement (LGE), sGCS was an independent predictor of a higher incidence of MACE (adjusted HR: 1.12 [95% CI, 1.05–1.20]). Finally, sGCS showed an incremental prognostic value to predict MACE compared to a multivariable model including traditional risk factors, the presence of inducible ischemia and LGE (C-statistic improvement: 0.05, p = 0.007; NRI= 0.169; IDI= 0.097; both p<0.001). Conclusions Automatic sGCS has an incremental prognostic value to predict MACE above traditional risk factors, and other stress CMR parameters.","PeriodicalId":11963,"journal":{"name":"European Journal of Echocardiography","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136161682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Main funding source(s): New Zealand National Heart Foundation Background The role of speckle tracking echocardiography has been expanding thanks to its utility in detecting subtle changes in cardiac function, and has prognostic value(1). Right atrial (RA) strain has shown promise in prognostication amongst patients with pulmonary hypertension and heart failure. It is associated with RA size, RV function and IVC size. However, its clinical utility and application remain under investigation (2–5). We sought to evaluate the associations of right atrial strain with both invasive and non-invasive measure of RV function and the association of RA strain with heart failure hospitalisations and death across a heterogeneous cohort. Methods A single-centre retrospective analysis of data from 225 consecutive patients (age 72 ±11.6 years old; male 56%) with both right heart catheterization (RHC) and TTE. Data regarding unplanned heart failure hospitalisations and date of death were recorded. Statistical analysis was performed using SAS 15.1 to assess the association between right atrial strain and prespecified echo and haemodynamic measures of right and left heart function and prognosis defined by heart failure hospitalisations and death. Results Over a median follow up of 28±16 months, there were 59 events. RA strain was associated with the following non-invasive and invasive measures of right heart function and left heart systolic function : TAPSE; RA size, RA pressure, RV strain, PAPi, RVSWI, RV FAC, LAVi, RV PA coupling (TAPSE/systolic PAP), LVEF, cardiac index, diastolic function (E/e’) with a p value of <0.05. Increasing atrial size was associated with lower values of R strain. Despite the association of impaired RV strain with prognosis, HR 2.94 (1.14 – 7.60), RA strain did not appear to be associated independently with prognosis HR 0.98 (0.95–1.0) P value = 0.0676. Conclusions Right atrial strain is independently associated with both invasive and non-invasive measures of RV function and may be a useful tool to help us assess right heart function. It did not appear to be associated with prognosis despite being independently linked with RV strain, which was strongly associated with prognosis in our cohort.","PeriodicalId":11963,"journal":{"name":"European Journal of Echocardiography","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136161752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background Current guidelines recommend intervention in severe degenerative mitral regurgitation (MR) in symptomatic patients or asymptomatic patients with left ventricular dilatation or dysfunction. The insidious onset of symptoms may mean patients do not report symptoms. The role of systematic exercise testing for symptoms in MR is not clearly defined. Methods 97 patients with moderate to severe, asymptomatic MR underwent exercise echocardiography combined with cardiopulmonary exercise testing. Predictors of exercise-induced dyspnoea, symptom-free survival and mitral valve intervention were identified. Results 18 (19%) patients developed limiting dyspnoea on exercise. Spontaneous symptom free survival at 24 months was significantly higher in those without exercise-induced symptoms compared to those with exercise-induced symptoms, p <0.0001. The only independent predictors of spontaneous symptoms at 2 years were effective regurgitant orifice area (odds ratio 27.45 (95% CI 1.43 – 528.40), p = 0.03) and exercise-induced symptoms (odds ratio 11.56 (95% CI 1.71 – 78.09), p = 0.01). The only independent predictor of surgery was indexed left ventricular systolic volumes (Odds ratio 1.17 (95% CI 1.04 – 1.30), p = 0.006). Where only patients undergoing surgery due to symptoms were included, the only independent predictor was exercise-induced symptoms (Odds ratio 13.94 (95% CI 1.39 – 140.27), p = 0.025).

Background Paediatric hypertrophic cardiomyopathy (HCM) is a leading cause of sudden death. The relationship between the genotype variation and phenotype expression has not been fully elucidated, with some studies showing association with an increased hypertrophy and MYH7 or multiple genetic variations. In HCM fibrosis and hypertrophy contribute to left ventricular (LV) mechanics’ alteration resulting in subendocardial dysfunction. The latter is associated with a decreased global longitudinal and radial strains (GLS, GRS), whereas epicardial thickening leads to preserved global circumferential strain (GCS) and LV twist. Children with HCM have reduced LA function, measurable by both volumetric and strain analysis and reduced LA mechanics are associated with poor exercise capacity. Feature tracking –cardiac magnetic resonance (FT-CMR) has enhanced the non-invasive assessment of myocardial deformation in HCM. The main aim of our study was to assess differences of LV and LA mechanics features on CMR between patients harbouring multiple pathogenic or likely pathogenic variants (MGv, n=16) or single genetic variations (SGv, n=35). Methods Our retrospective CMR study included 51 patients (1.7–18.8 years ago). CMR data were: LV and LA’s morphological values, late gadolinium enhancement (LGE) of LA and LV walls, LV feature tracking (FT) derived strain and LV twist (LVT). LV twist was calculated as the difference between basal and apical rotation. The LA feature FT derived strain, LA conduit function, reservoir function and pump function were computed. Results In MGv group, the indexed LV mass 108.8 +/-53.0 vs 74.3+/- 22.2 in SGv (p = 0.03). LGE was present in 51% patients of the whole cohort, with LGE in 64 % of MGv group. LV FT derived strain values and LA function were not statistically significant different between groups (MGv vs SGv: GLS −15.8+/−5.3 vs −18.7+/−4.8, GCS −27.8+/8 vs −31.1+/−8.6, GRS 44.7+/−24.6 vs 62.3+/−32). LVT was reduced in MGv group (0.04+/−7.6) vs (7.4+/−7.4) in SGv (p = 0.003). LA contractile function did not differ between the groups (MGv vs SGv: GLS LA 25.1+/−14.2 vs 27.6+/−13.5). LA reservoir, conduction and pump function did not differ between the groups. LVT was significantly correlated with the LA contractile function. An increased of LVT was associated with an increased LA GLS and EF (p = 0.011; p = 0.004). Conclusions Patients with multiple genetic variants have a greater LV mass and altered LV mechanics with reduced LV twist. This study gives insights in phenotype- genotype correlation in paediatric HCM and warrants larger longitudinal studies to assess its clinical significance.","PeriodicalId":11963,"journal":{"name":"European Journal of Echocardiography","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136161894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background Heart transplanted patients are usually monitored with invasive diagnostic techniques for detecting cardiac allograft vasculopathy (CAV). However coronary CT angiography (CCTA) is a new promising tool in the initial stages of CAV bringing clinical and economical benefits. Purpose 1) assess the non-inferiority of CCTA in comparison to coronary angiography (CA), in terms of radiation and contrast dose, costs, hospitalization hours, complications and diagnostic accuracy; 2) analyse the different role of immunological and non-immunological risk factors predicting CAV in patients undergoing CCTA; 3) Investigate the rule of coronary inflammation through the pericoronary-fat-attenuation-index (pFAI) at CCTA in the progression of CAV. Methods 179 heart transplanted patients were retrospectively analysed: 78 performed a CCTA and 101 performed a CA between March 2021 and May 2022. Results CCTA and CA showed similar radiation doses (8.47 [1.46–30] versus 8.15 [1.38–87.34]; p = 0.796) and rate of complications (0 (0%) vs 3 (3%); p = 0,258). CCTA in comparison with CA required less hours of hospitalization (0.5 hours versus 23.7 12.31 hours; p<0.001), lower costs (120 euros versus 2800 euros; p<0.001) and less contrast agent (60.4 8.7 ml versus 95.68 47.6ml; p<0.001). Diagnostic accuracy was similar between CCTA and CA (95% vs 100%; p = 0,169). Among the non immunological risk factors for CAV, only smoking showed a statistically significance in predicting CAV (p = 0.015). Among immunological risk factors, TNF was the only independent predictor in the progression of CAV (HR 8.23; IC 95% 1.47–45.81; p = 0.019). There were no statistically correlation between pFAI at CCTA either as a continuous variable or as a categorical variable (>-70.1HU) and the progression of CAV (p = NS). Conclusions CCTA is similar to CA in terms of radiation dose and rate of complications and is superior in terms of hospitalization hours, costs and contrast agent injected. Diagnostic accurancy was equivalent between CCTA and CA. TNF was the only independent predictor in the progression of CAV.

Background Although lung ultrasound has been reported to be a portable, cost-effective, and accurate method to detect pneumonia, it has not been widely used because of the difficulty in its interpretation. Purpose We aimed to investigate the effectiveness of a novel artificial intelligence-based automated pneumonia detection method using point-of-care lung ultrasound (AI-POCUS) for the coronavirus disease 2019 (COVID-19). Methods We enrolled consecutive patients admitted with COVID-19 who underwent computed tomography (CT) in August and September 2021. A 12-zone AI-POCUS was performed by a novice observer using a pocket-size device within 24 h of the CT scan. Fifteen control subjects were also scanned. Additionally, the accuracy of the simplified 8-zone scan excluding the dorsal chest, was assessed. More than three B-lines detected in one lung zone were considered zone-level positive, and the presence of positive AI-POCUS in any lung zone was considered patient-level positive. The sample size calculation was not performed given the retrospective all-comer nature of the study. Results A total of 577 lung zones from 56 subjects (59.4 ± 14.8 years, 23% female) were evaluated using AI-POCUS. The mean number of days from disease onset was 9, and 14% of patients were under mechanical ventilation. The CT-validated pneumonia was seen in 71.4% of patients at total 577 lung zones (53.3%). The 12-zone AI-POCUS for detecting CT-validated pneumonia in the patient-level showed the accuracy of 94.5% (85.1% – 98.1%), sensitivity of 92.3% (79.7% – 97.3%), specificity of 100% (80.6% – 100%), positive predictive value of 95.0% (89.6% − 97.7%), and Kappa of 0.33 (0.27 – 0.40). When simplified with 8-zone scan, the accuracy, sensitivity, and sensitivity were 83.9% (72.2% – 91.3%), 77.5% (62.5% – 87.7%), and 100% (80.6% – 100%), respectively. The zone-level accuracy, sensitivity, and specificity of AI-POCUS were 65.3% (61.4% – 69.1%), 37.2% (32.0% – 42.7%), and 97.8 % (95.2% – 99.0%), respectively. Conclusion AI-POCUS using the novel pocket-size ultrasound system showed excellent agreement with CT-validated COVID-19 pneumonia, even when used by a novice observer.","PeriodicalId":11963,"journal":{"name":"European Journal of Echocardiography","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136161749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
