Introduction COVID-19 patients present impaired subclinical markers of cardiovascular and endothelial function. Subclinical myocardial and vascular dysfunction during COVID-19 disease have been associated with worse outcomes and higher mortality risk. Purpose We investigated the effect of COVID-19 infection on markers of endothelial, vascular and myocardial function at four and twelve months after the infection Methods We recruited 70 patients who were examined in a dedicated post-COVID-19 outpatient clinic during a scheduled follow-up visit at four and twelve months after a confirmed COVID-19 infection and 70 healthy individuals with similar clinical characteristics. At four and twelve months we measured (i) perfused boundary region (PBR) of the sublingual arterial microvessels (increased PBR indicates reduced endothelial glycocalyx thickness), (ii) flow-mediated dilatation (FMD), (iii) coronary flow reserve (CFR) by Doppler echocardiography, (iv) pulse wave velocity (PWV) and central systolic blood pressure (cSBP), (v) global left and right ventricular longitudinal strain (GLS), (vi) myocardial global work index (GWI) global constructive work (GCW), global wasted work (GWW) and the myocardial global work efficiency (GWE) and v) malondialdehyde (MDA), an oxidative stress marker. Results At four months, COVID-19 patients displayed higher values of PBR5–25 compared to control group (p<0.001) which increased at twelve months (p<0.001). FMD, PWV and cSBP values were similar between 4 and 12 months (p>0.05 for all the comparisons) and higher than those in controls (p<0.001, p = 0.057, p = 0.003 respectively). At four months, COVID-19 patients presented impaired CFR and LVGLS values which were improved at twelve months (p = 0.002, p = 0.069 respectively), though remained impaired compared to controls (p = 0.003 for all the comparisons). At four months, COVID-19 patients had impaired RVGLS values which were significantly improved at twelve months (p = 0.001) and showed no statistically significant difference compared to controls (p>0.05). COVID-19 patients at four months display higher myocardial wasted work and decreased myocardial efficiency compared to controls (p = 0.01, p = 0.006, respectively). There was a modest improvement in GWW and GWE at twelve months, (p = 0.043, p = 0.001, respectively); however, these markers remained impaired compared to controls (p>0.05). At four months, MDA was higher in COVID-19 patients compared to control group and significantly decreased at twelve months (p<0.001); however, these values remain higher than in controls (p = 0.002). Conclusions SARS-CoV-2 causes endothelial and cardiovascular dysfunction which are partially restored at twelve months after the infection.","PeriodicalId":11963,"journal":{"name":"European Journal of Echocardiography","volume":"10 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":"136161688","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 Several studies described the independent prognostic value of left ventricular global longitudinal strain (GLS) using cardiovascular magnetic resonance (CMR) to predict cardiovascular events. However, the potential interest of GLS using a fully automatic method assessed at rest during a stress CMR exam was not well established. Aim To assess the prognostic value of GLS to predict all-cause death 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 all-cause death. A fully automatic machine learning algorithm was trained and validated unseen CMR studies (MAGNETOM Aera and Skyra, Siemens Healthcare, Erlangen, Germany) to assess the GLS from long-axis cine images acquired at rest. 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 GLS. Results Among 9,883 consecutive patients who underwent stress CMR between 2016 and 2018 retrospectively included, the automatic GLS was successfully computed in 9,638 (97.5%) patients (67% male, mean age 66±12 years). A total of 510 (5.3%) deaths were observed during a median (IQR) follow-up period of 4.5 (3.7–5.2) years. GLS, the presence of inducible ischemia and late gadolinium enhancement (LGE) were significantly associated with the occurrence of death (hazard ratio, HR: 1.22 [95% CI, 1.17–1.26]; HR: 2.23 [95% CI, 1.61–3.10]; and HR: 2.04 [95% CI, 1.41–2.95], respectively, all p<0.001). After adjustment for traditional risk factors, inducible ischemia and LGE, GLS was an independent predictor of a higher incidence of death (adjusted HR: 1.14 [95% CI, 1.08–1.20]). Automatic GLS showed an incremental prognostic value to predict death compared to traditional risk factors, inducible ischemia and LGE (C-statistic improvement: 0.05; NRI=0.146; IDI=0.244; all p<0.001). Conclusions Automatic GLS measured at rest has an incremental prognostic value to predict all-cause death 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":"136161840","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 Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), also referred to as COVID-19, was declared a pandemic by the World Health Organization in March 2020. The manifestations of COVID-19 are widely variable and range from asymptomatic infection to multi-organ failure and death. Like other viral illnesses, acute myocarditis and/or pericarditis has been reported to be associated with COVID-19 infection. The guidelines for the diagnosis of COVID-19 introduced the echocardiogram for diagnosis of carditis in these patients Pourpose In our study we investigated the incidences of myocarditis and/or pericarditis in a consecutive series of 1540 Athletes undergo to agonistic certification.

Background Assessment of inducible ischemia with stress cardiovascular magnetic resonance (CMR) is recommended in patients with chest pain and intermediate or high pre-test probability of coronary artery disease (CAD). We aimed to provide a contemporary quantitative data synthesis on diagnostic accuracy and prognostic value of stress CMR in patients with stable chest pain syndromes. Methods We performed a prespecified systematic review and meta-analysis of studies published over the last twenty years on the diagnostic and prognostic value of stress CMR (PROSPERO: CRD42022299275). We measured pooled diagnostic indicators, including diagnostic odds ratio (DOR), sensitivity, specificity, area under the curve (AUC), and summary effect size indicators, including odds ratios (ORs) and cumulative annualized event rates (AERs) for all-cause death, cardiovascular death and major adverse cardiac events (MACE). Results We identified 33 diagnostic studies pooling 7,815 individuals (mean age, 62 years, 62% males) and 31 prognostic studies pooling 67,080 patients (mean age, 62 years; 57% males; mean follow-up 3.5 years for a total of 381,357 person-years). Stress CMR yielded a pooled DOR of 26.4 (95%CI:10.6–65.9), a sensitivity of 81% (95%CI:68–89%), a specificity of 86% (95%CI:75–93%), and an AUC of 0.84 (95%CI:0.77–0.89) for the detection of functionally obstructive CAD with fractional flow reserve as the reference test. In subgroup analysis, 3 Tesla imaging yielded higher diagnostic accuracy achieving a DOR of 33.2. Presence of stress-inducible ischemia was associated with higher all-cause mortality (OR:2.0; 95%CI:1.7–2.3), cardiovascular mortality (OR:6.4; 95%CI:4.5–9.1), and increased risk of MACE (OR:5.3; 95%CI:4.0–7.0). AERs for cardiovascular death and MACE were < 1% in patients without stress-inducible ischemia. Conclusion Stress CMR yields high diagnostic accuracy and delivers robust prognostication in patients with stable chest pain and known or suspected CAD, particularly with 3 Tesla imaging. While inducible ischemia portends excess mortality and increased risk of MACE, a negative stress CMR indicates a very low risk of future cardiovascular events, with a warranty period of at least 3.5 years.","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":"136161415","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/Introduction Clinically relevant tricuspid regurgitation is a prevalent valvular disease that has a significant impact on survival. The remarkable progress made in cardiac imaging and in interventional cardiology in the last decades, permits today a better understanding of tricuspid valve and right ventricle morphology and pathophysiology. This allowed to develop multiple transcatheter devices for tricuspid valve interventions. Structural valve interventions are considered nowadays valuable treatment options in anatomically eligible patient at high surgical risk. Transcatheter tricuspid valve interventions are directed to increasing leaflet coaptation either directly by bringing the leaflets together (leaflet approximation devices) or indirectly by reducing the dilated annulus (annuloplasty devices). Efficacy and clinical outcome are promising, but the effect on right ventricle and tricuspid annular reverse remodelling is still under evaluation. Purpose Aim of the study is to evaluate the acute tricuspid annulus remodelling after percutaneous leaflet repair, using a leaflet approximation device for reduction of tricuspid regurgitation. Methods This is a retrospective dual-center cohort study that includes 22 consecutive patients, treated with TriClip in our Hospital. Tricuspid annulus geometry was evaluated using three-dimensional transoesophageal echocardiography examinations conducted during the procedure before and after Triclip implantation. The 3D data sets were analysed using the multiplanar reformatting method. Results The mean age of the study cohort was 80 years, and 90,9% were female. Tricuspid regurgitation was graded severe or greater at pre-operative examination in all patients, mostly due to annular dilation. Procedure was successfully in all patients, with at least 1-grade reduction of tricuspid regurgitation before hospital dismissal. A significative reduction of mean septal-lateral diameter (4,09 ± 0,45 cm vs 3,55 ± 0,57 cm, p = < 0,0001), mean major diameter (4,60 ± 0,56 cm vs 4,24 ± 0,58 cm, p = 0,0011), planimetric area (13,70 ± 2,68 cm2 vs 11,00 ± 2,49 cm2, p = <0,0001) and perimeter (13,50 ± 1,36 cm vs 12,40 ± 1,49 cm, p = 0,0001) of the tricuspid annulus was observed. The eccentricity index (obtained dividing septal-lateral by antero-posterior diameter) was 0,99±0,17 before TriClip implantation and 0,91± 0,19 after (p = 0,0336). Conclusions In this small real-world population, edge-to-edge repair using TriClip was found to be effective and safe. Tricuspid transcatheter repair with a leaflet approximation device lead also to a reduction in the tricuspidal annular dimensions. This is to date the first study that shows positive changes in tricuspid annular geometry, that could have potentially relevant therapeutic implications.","PeriodicalId":11963,"journal":{"name":"European Journal of Echocardiography","volume":"9 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":"136161577","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 Various definitions of very severe (VS) tricuspid regurgitation (TR) have been proposed based on the effective regurgitant orifice area (EROA) or tricuspid coaptation gap (TCG). Because of the inherent limitations associated with the EROA, we hypothesized that the TCG would be more suitable for defining VSTR and predicting outcomes. Purpose To compare EROA and TCG for outcome prediction in patients with severe TR Methods In this French multicentre retrospective study, we included 606 patients with ≥ moderate-to-severe isolated TR (without structural valve disease or an overt cardiac cause) according to the recommendations of the European Association of Cardiovascular Imaging. Patients were further stratified into VSTR according to the EROA (≥60 mm²) and then according to the TCG (≥10 mm). The primary endpoint was all-cause mortality and the secondary endpoint was cardiovascular mortality. Results The relationship between the EROA and TCG was poor (R²=0.21), especially when the size of the defect was large. Four-year survival was comparable between patients with an EROA <60 mm² vs. ≥ 60 mm² (67±3% vs. 64±4%, p = 0.64), even after adjustment, for all-cause (p = 0.72) and cardiovascular mortality (p = 0.18). A TCG ≥10 mm was associated with lower four-year survival than a TCG <10 mm (53±7% vs. 69±3%, p<0.001). After adjustment for covariates, including age, comorbidity, right heart failure, dose of diuretics, and right ventricular dysfunction, a TCG ≥10 mm remained independently associated with higher all-cause mortality (adjusted HR[95%CI]=1.46[1.15–2.18], p = 0.015) and cardiovascular mortality (adjusted HR[95%CI]=1.95[1.22–3.14], p <0.001), whereas an EROA ≥60 mm² was not associated with all-cause or cardiovascular mortality (adjusted HR[95%CI]:1.07[0.75–1.51], p = 0.720, and adjusted HR[95%CI]:1.35[0.87–2.09], p = 0.176, respectively) Conclusion The correlation between the TCG and EROA is weak and decreases with increasing defect size. A TCG ≥10mm is associated with increased all-cause and cardiovascular mortality and should be used to define VSTR in isolated TR.","PeriodicalId":11963,"journal":{"name":"European Journal of Echocardiography","volume":"9 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":"136161836","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 Implantable cardiac defibrillator (ICD) implantation can protect against sudden cardiac death (SCD) after a myocardial infarction. However, relatively few patients with an ICD experience a life-threatening arrhythmic event. Imaging studies have proposed metrics based on 2D analysis of late gadolinium enhancement (LGE) characteristics to predict post-infarct malignant arrhythmias and improve SCD risk assessment. However, given the intrinsic 3D nature of the electrical pathways through the infarcted regions, 3D reconstructions of the scar substrate from LGE imaging may be required to fully characterize the pro-arrhythmic nature of the scar substrate. Aim To evaluate the accuracy of LGE based 3D metrics such as conduction corridors (regions of borderzone (BZ) surrounded by scar core) and 3D interface surfaces (boundaries between scar and myocardium) towards predicting ICD therapy. Methods ADAS LV and custom-made software was used to generate 3D patient-specific ventricular models in a prospective cohort of post-infarct patients (n=40) having undergone LGE imaging pre-ICD implantation. The extent of variation in scar-characteristics was evaluated in ADAS by quantifying the BZ, scar core, the number and weight of conduction corridors i.e. BZ surrounded by scar core. Custom-written scripts were used to calculate metrics describing the 3D topology of the scar substrate, specifically the interface area between myocardium and total enhancement (BZ+core), and the interface between BZ and core. These metrics were compared with ICD therapy during follow-up. Results Total corridors were comparable between both groups (6.53 ± 7.9 vs. 4.6 ± 4, p = .38). Corridor weight demonstrated a trend towards higher mass in the event group (2.7 ± 2.1g vs. 1.6 ± 1.4g, p = .06). Patients with an event (n=17) had higher myocardium-total enhancement interface (103.8±35.1cm2 vs. 77.4±33.7cm2, p = .021) and BZ-core interface (76±27.5cm2 vs. 55.2±27.6cm2, p = .024). Cox-regression demonstrated a significant independent association of myocardium-total enhancement interface with an event (HR 2.79; 1.44–5.44, p < .01). Kaplan-Meier analysis (Figure 1) showed a significantly higher event rate in patients with an interface area between myocardium-total enhancement of more than 72cm2 and BZ-core more than 42.3cm2. Conclusion These results demonstrate that patients with appropriate device therapy had larger myocardium-total enhancement and BZ-core surface interface areas. Conceptually, the BZ-core interface could be considered to be related to the reentrant circuit path-length whilst the myocardium-total enhancement interface reflects the surfaces most-likely to initiate unidirectional block, both of which can be consider pro-arrhythmic substrates.

Background the prognostic role of left ventricular (LV) papillary muscle abnormalities in patients with preserved LV systolic ejection fraction (LVEF) is unknown. Aim to evaluate the prevalence and the clinical and prognostic impact of papillary muscle abnormalities by CMR in patients with ventricular arrhythmias, preserved LVEF with no cardiac disease. Methods 391 patients with >500/24h premature ventricular complexes and/or with non-sustained ventricular tachycardia (NSVT), preserved LVEF and no cardiac disease, were enrolled. Different features of LV papillary muscles were considered: supernumerary muscles, papillary thickness, the attachment, late gadolinium enhancement (LGE). The end-systolic hypointensity was defined when its measured signal intensity (SI) was lower than the SI of the septum in early post-contrast cine CMR images. Dark-Paps was defined when both the main papillary muscles had systolic hypointensity. Mitral valve prolapse, mitral annular disjunction (MAD), myocardial LGE were considered. The outcome of hard cardiac events was define as a composite of cardiac death, resuscitated cardiac arrest, and appropriate implantable cardioverter defibrillator (ICD) shock, sustained ventricular tachycardia (lasting ≥30 s at ≥100 beats/min). Results Dark-Paps was found in 79 (20%) patients and was more frequent in females. It was associated with higher prevalence of mitral valve prolapse and MAD.

Background Although some recent reports showed that fully automated artificial intelligence (AI)-based left ventricular ejection fraction (LVEF) measured at stress has good performance, its prognostic value during a stress CMR exam to predict outcomes is not well established. Aim To determine in patients undergoing stress CMR whether fully automated AI-based LVEF (LVEF-AI) measured at stress can provide incremental prognostic value to predict death. Methods Between 2016 and 2018, we conducted a longitudinal study including all consecutive patients referred for vasodilator stress CMR. LVEF-AI was assessed using AI-algorithm combines multiple deep learning networks for LV segmentation. The primary outcome was all-cause death defined by the French National Registry of Death. Cox regression was used to evaluate the association of stress LVEF-AI with death after adjustment for traditional risk factors. Results In 9,712 patients (66±15 years, 67% men), there was an excellent correlation between stress LVEF-AI measurement and LVEF measured by expert (LVEF-expert) (r=0.94, p<0.001). Using Bland–Altman analysis, we found that the difference between the mean LVEF-expert and the LVEF-AI group was −0.1% (−0.066–0.067), that was not statistically significant (p = 0.46). Stress LVEF-AI was associated with death (median [IQR] follow-up 4.5 [3.7–5.2] years) before and after adjustment for risk factors (adjusted hazard ratio [HR], 0.84 [95% CI, 0.82–0.87] per 5% increment, p<0.001). Stress LVEF-AI had similar significant association with death occurrence compared with LVEF-expert. After adjustment, a lower stress LVEF-AI showed the greatest improvement in model discrimination and reclassification over and above traditional risk factors and stress CMR findings (C-statistic improvement: 0.11; NRI=0.250; IDI=0.049, all p<0.001; LR-test p<0.001), with a superior additional prognostic value than the LVEF-AI measured at rest. Conclusion AI-based fully automated LVEF measured at stress is independently associated with the occurrence of death in patients undergoing stress CMR, with an additional prognostic value above traditional risk factors, inducible ischemia and LGE.","PeriodicalId":11963,"journal":{"name":"European Journal of Echocardiography","volume":"20 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":"136161888","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}

Introduction Guidelines recommend replacement in patients with severe aortic stenosis (AS) who present with symptoms or left ventricular ejection fraction (LVEF) < 50%, both conditions representing a late stage of the disease. While global longitudinal strain (GLS) is load dependant but interesting for assessing prognosis, myocardial work has emerged. We aim to evaluate acute changes in myocardial work occurring in patients undergoing transcatheter aortic valve implantation (TAVI). Methods Patients who underwent TAVI were evaluated before and after by echocardiography. Complete echocardiographies were considered. Myocardial work indices (global work index (GWI), Global constructive work (GCW), Global work efficiency (GWE), Global wasted work (GWW)) were calculated integrating mean transaortic pressure-gradient and brachial-cuff systolic pressure. Results 125 patients underwent successful TAVI with significant decrease of the transaortic mean gradient (52.5 ± 16.1 to 12.2 ± 5.0, P<.0001). There was no significant change in LVEF post-TAVI. Myocardial work data post-TAVR showed a significant reduction of GWI (1389 ± 537 vs. 2014 ± 714, P<.0001), GCW (1693 ± 543 vs. 2379 ± 761, P<.0001) and GWE (85,0 ± 7,06 vs. 87,1 ± 5,98, P=0,0034). Decrease of GWI and GCW after TAVI was homogeneous among different sub-groups based on their GLS, LVEF of NYHA status before TAVI. We observed a significant association between GWI and GCW before TAVI and a GLS degradation after TAVI. Conclusion Myocardial work parameters show promising potential in best understanding the LV-myocardial consequences of AS and its correction. By their ability to discriminate NYHA status and GLS evolution, we can hypothesize on their clinical value.","PeriodicalId":11963,"journal":{"name":"European Journal of Echocardiography","volume":"1 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":"136161575","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}
