RESUMEN

BACKGROUND: There are sex differences in HF patients. It is not clear whether such differences mainly reflect cultural behaviours and clinical inertia, and the role of sex on clinical outcomes is still controversial. We aimed to investigate the association of sex with in-hospital management and outcomes in patients with HF. METHODS: We analyzed data of 4016 adult patients hospitalized for HF in 2020-2021 and enrolled in a multicentre national registry. RESULTS: Women (n=1818[45%]) were older than men (83vs77 years, p<0.0001), with a higher prevalence of arterial hypertension (73%vs69%, p=0.011) and atrial fibrillation. Women presented more frequently with HF and preserved ejection fraction -HFpEF (55%vs32%, p<0.001). They were more often hospitalized in internal medicine departments (71%vs51%), and men in highly specialized cardiology units (49%vs29%). When considering HF pharmacological treatments at discharge in the subgroup with reduced ejection fraction -HFrEF (n=1525), there were no significant differences (49% of women treated with GDMT [guideline-directed medical therapy] vs 52% of men, p=0.197). Sex was not associated either with hospital readmissions (30-days OR[95%CI]=0.89[0.71-1.11], p=0.304; 1-year OR[95%CI]=1.02[0.88-1.19], p=0.777) or with mortality (in-hospital OR[95%CI]=1.14[0.73-1.78], p=0.558; 1-year OR[95%CI]=1.08[0.87-1.33], p=0.478). Similar results were obtained when considering different HF categories based on left ventricular ejection fraction. CONCLUSIONS: Women and men exhibited distinct clinical profiles. Although this may have had an impact on hospital pathways (non-cardiology/cardiology units) and pharmacological prescriptions, sex per se did not appear as an independent determinant of clinical choices. Moreover, when considering homogeneous groups, women were not undertreated. Finally, female sex was not associated with worse clinical outcomes.

RESUMEN

BACKGROUND: The impact of prosthesis-patient mismatch (PPM) on major endpoints after transcatheter aortic valve replacement (TAVR) is controversial and the effects on progression of heart damage are poorly investigated. Therefore, our study aims to evaluate the prevalence and predictors of PPM in a "real world" cohort of patients at intermediate and low surgical risk, its impact on mortality and the clinical-echocardiographic progression of heart damage. METHODS: 963 patients who underwent TAVR procedure between 2017 and 2021, from the RECOVERY-TAVR international multicenter observational registry, were included in this analysis. Multiparametric echocardiographic data of these patients were analyzed at 1-year follow-up (FU). Clinical and echocardiographic features were stratified by presence of PPM and PPM severity, as per the most current international recommendations, using VARC-3 criteria. RESULTS: 18% of patients developed post-TAVR. PPM, and 7.7% of the whole cohort had severe PPM. At baseline, 50.3% of patients with PPM were male (vs 46.2% in the cohort without PPM, P = .33), aged 82 (IQR 79-85y) years vs 82 (IQR 78-86 P = .46), and 55.6% had Balloon-Expandable valves implanted (vs 46.8% of patients without PPM, P = .04); they had smaller left ventricular outflow tract (LVOT) diameter (20 mm, IQR 19-21 vs 20 mm, IQR 20-22, P = .02), reduced SVi (34.2 vs 38 mL/m2, P < .01) and transaortic flow rate (190.6 vs 211 mL/s, P < .01). At predischarge FU patients with PPM had more paravalvular aortic regurgitation (moderate-severe AR 15.8% vs 9.2%, P < .01). At 1-year FU, maladaptive alterations of left ventricular parameters were found in patients with PPM, with a significant increase in end-systolic diameter (33 mm vs 28 mm, P = .03) and a significant increase in left ventricle end systolic indexed volume in those with moderate and severe PPM (52 IQR 42-64 and 52, IQR 41-64 vs 44 IQR 35-59 in those without, P = .02)). No evidence of a significant impact of PPM on overall (P = .71) and CV (P = .70) mortality was observed. Patients with moderate/severe PPM had worse NYHA functional class at 1 year (NYHA III-IV 13% vs 7.8%, P = .03). Prosthesis size≤23 mm (OR 11.6, 1.68-80.1) was an independent predictor of PPM, while SVi (OR 0.87, 0.83-0.91, P < .001) and LVOT diameter (OR 0.79, 0.65-0.95, P = .01) had protective effect. CONCLUSIONS: PPM was observed in 18% of patients undergoing TAVR. Echocardiographic evaluations demonstrated a PPM-related pattern of early ventricular maladaptive alterations, possibly precursor to a reduction in cardiac function, associated with a significant deterioration in NYHA class at 1 year. These findings emphasize the importance of prevention of PPM of any grade in patients undergoing TAVR procedure, especially in populations at risk.

RESUMEN

The use of left ventricular assist devices (LVAD) has significantly increased in the last years, trying to offer a therapeutic alternative to heart transplantation, in light also to the significant heart donor shortage compared to the growing advanced heart failure population. Despite technological improvements in the devices, LVAD-related mortality is still fairly high, with right heart failure being one of the predominant predictors. Therefore, many efforts have been made toward a thorough right ventricular (RV) evaluation prior to LVAD implant, considering clinical, laboratory, echocardiographic, and invasive hemodynamic parameters. However, there is high heterogeneity regarding both which predictor is the strongest as well as the relative cut-off values, and a consensus has not been reached yet, increasing the risk of facing patients in which the distinction between good or poor RV function cannot be surely reached. In parallel, due to technological development and availability of mechanical circulatory support of the RV, LVADs are being considered even in patients with suboptimal RV function. The aim of our review is to analyze the current evidence regarding the role of RV function prior to LVAD and its evaluation, pointing out the extreme variability in parameters that are currently assessed and future prospective regarding new diagnostic tools. Finally, we attempt to gather the available information on the therapeutic strategies to use in the peri-operative phase, in order to reduce the incidence of RV failure, especially in patients in which the preoperative evaluation highlighted some conflicting results with regard to ventricular function.

RESUMEN

Heart failure (HF) is a clinical syndrome characterized by well-defined signs and symptoms due to structural and/or myocardial functional impairment, resulting in raised intracardiac pressures and/or inadequate cardiac stroke volume at rest or during exercise. This could derive from direct ischemic myocardial injury or other chronic pathological conditions, including valvular heart disease (VHD) and primary myocardial disease. Early identification of HF etiology is essential for accurate diagnosis and initiation of early and appropriate treatment. Thus, the presence of accurate means for early diagnosis of HF symptoms or subclinical phases is fundamental, among which echocardiography being the first line diagnostic investigation. Echocardiography could be performed at rest, to identify overt structural and functional abnormalities or during physical or pharmacological stress, in order to elicit subclinical myocardial function impairment e.g. wall motion abnormalities and raised ventricular filling pressures. Beyond diagnosis of ischemic heart disease, stress echocardiography (SE) has recently shown its unique value for the evaluation of diastolic heart failure, VHD, non-ischemic cardiomyopathies and pulmonary hypertension, with recommendations from international societies in several clinical settings. All these features make SE an important additional tool, not only for diagnostic assessment, but also for prognostic stratification and therapeutic management of patients with HF. In this review, the unique value of SE in the evaluation of HF patients will be described, with the objective to provide an overview of the validated methods for each setting, particularly for HF management.

RESUMEN

International Guidelines consider left ventricular ejection fraction (LVEF) as an important parameter to categorize patients with heart failure (HF) and to define recommended treatments in clinical practice. However, LVEF has some technical and clinical limitations, being derived from geometric assumptions and is unable to evaluate intrinsic myocardial function and LV filling pressure (LVFP). Moreover, it has been shown to fail to predict clinical outcome in patients with end-stage HF. The analysis of LV antegrade flow derived from pulsed-wave Doppler (stroke volume index, stroke distance, cardiac output, and cardiac index) and non-invasive evaluation of LVFP have demonstrated some advantages and prognostic implications in HF patients. Speckle tracking echocardiography (STE) is able to unmask intrinsic myocardial systolic dysfunction in HF patients, particularly in those with LV preserved EF, hence allowing analysis of LV, right ventricular and left atrial (LA) intrinsic myocardial function (global peak atrial LS, (PALS)). Global PALS has been proven a reliable index of LVFP which could fill the gaps "gray zone" in the previous Guidelines algorithm for the assessment of LV diastolic dysfunction and LVFP, being added to the latest European Association of Cardiovascular Imaging Consensus document for the use of multimodality imaging in evaluating HFpEF. The aim of this review is to highlight the importance of the hemodynamics multiparametric approach of assessing myocardial function (from LVFP to stroke volume) in patients with HF, thus overcoming the limitations of LVEF.

RESUMEN

OBJECTIVE: Concerns exist about the possible detrimental effects of exercise training on aortic size and valve function in individuals with bicuspid aortic valve (BAV). This multicentre international study aimed to determine the characteristics of aortic size and valve function in athletes versus non-athletes with BAV and athletes with tricuspid aortic valve (TAV). METHODS: We enrolled competitive athletes with BAV and age- and sex-matched athletes with TAV and non-athletes with BAV. We assessed valve function, aortic size and biventricular measures using echocardiography. Individuals with established moderate-severe AV stenosis, regurgitation or significant aortic dilation were excluded from the study. RESULTS: The study population comprised 504 participants: 186 competitive athletes with BAV (84% males; age 30±11 years), 193 competitive athletes with TAV and 125 non-athletes with BAV. The aortic annulus was greater in athletes with BAV than athletes with TAV and non-athletes with BAV (p<0.001). Both athletic and non-athletic individuals with BAV had greater sinuses of Valsalva, sino-tubular junction and ascending aorta diameters than athletes with TAV (p<0.001). However, no significant differences were found between athletes and non-athletes with BAV. Left ventricular index volumes and mass were greater in athletes with BAV than in the other two groups (p<0.001). Individuals with BAV (athletes and non-athletes) had greater mean gradients than TAV athletes. CONCLUSION: This multicentre international study demonstrates no differences between athletes with BAV and non-athletes with BAV regarding aortic valve function or aortic dimensions. However, athletes with BAV have larger aortic diameters and a relatively worse valvular function than athletes with TAV.

RESUMEN

Lipid disorders represent one of the most worrisome cardiovascular risk factors. The focus on the impact of lipids on cardiac and vascular health usually concerns low-density lipoprotein cholesterol, while the role of triglycerides (TGs) is given poor attention. The literature provides data on the impact of higher plasma concentrations in TGs on the cardiovascular system and, therefore, on the outcomes and comorbidities of patients. The risk for coronary heart diseases varies from 57 to 76% in patients with hypertriglyceridemia. Specifically, the higher the plasma concentrations in TGs, the higher the incidence and prevalence of death, myocardial infarction, and stroke. Nevertheless, the metabolism of TGs and the exact physiopathologic mechanisms which try to explain the relationship between TGs and cardiovascular outcomes are not completely understood. The aims of this narrative review were as follows: to provide a comprehensive evaluation of the metabolism of triglycerides and a possible suggestion for understanding the targets for counteracting hypertriglyceridemia; to describe the inner physiopathological background for the relationship between vascular and cardiac damages derived from higher plasma concentrations in TGs; and to outline the need for promoting further insights in therapies for reducing TGs plasma levels.

RESUMEN

The prevalence of cardiac amyloidosis has progressively increased over the last years, being recognized as a significant cause of heart failure. In fact, the management of advanced heart failure is a cornerstone treatment of amyloid cardiomyopathy due to the frequent delay in its diagnosis. Left ventricular assist devices (LVADs) have been gaining importance in the scenario of end-stage heart failure, representing an alternative to heart transplant. However, only few studies have investigated the role of LVAD in restrictive cardiomyopathies such as cardiac amyloidosis, since there are several problems to consider. In fact, both anatomical factors and the restrictive physiology of this condition make LVAD implant a relevant challenge in this subset of patients. Furthermore, due to the systemic involvement of amyloidosis, several factors have to be considered after LVAD implant, such as an increased risk of bleeding and right ventricular failure. This review attempts to summarize the current evidence of LVAD in cardiac amyloidosis, especially focusing on the challenges that this cardiomyopathy imposes both to the implant and to its management thereafter.

RESUMEN

Background: To investigate the impact of Cryo Nerve Block with cryoICE™ device utilization, on post-operative pain in patients undergoing isolated coronary artery bypass grafting (CABG) through left thoracotomy. Methods: All consecutive patients undergoing isolated CABG through left thoracotomy between July 2021 and July 2022 from a single surgeon were included in the study. Patients using the cryoICE™ device for nerve block were compared for baseline demographics and pre-operative characteristics with those that did not use the cryoICE™ device. A propensity-adjusted analysis was used to compare the two groups. The primary outcome was degree of incisional pain and numbness. Results: A total of 103 patients underwent isolated CABG through left thoracotomy. After matching, the cryoICE™ device was used for nerve block in 60 patients while the control group included 43 patients. Mean follow-up was 5.7 months. The cryoICE™ device group had a mean value of incisional pain at hospital discharge was 1.5 (scale 0-10) while at follow-up was 0.69 (scale 0-10). Mean values of skin numbness at hospital discharge were 1 (scale 0-10) and 0.57 (scale 0-10) at follow-up. After univariate analysis comparison of cryoICE™ device group (60 patients) versus non-cryoICE™ device group (43 patients), the total in-hospital morphine use was 49% lower in the cryoICE™ versus the non-cryoICE™ cohort (73.8 + 79.37 mg vs 144.1 + 118.99 mg). Conclusions: Good clinical outcomes were observed in patients undergoing isolated left thoracotomy CABG with cryoICE™ utilization, including a very low incidence of post-operative pain, numbness, and hypersensitivity for all comers.

RESUMEN

BACKGROUND: Chronic total occlusion (CTO) revascularization is a major source of radiation for both patients and physicians. Therefore, efforts to minimize radiation during CTO percutaneous coronary intervention (PCI) are highly encouraged. AIMS: To evaluate the impact of an Ultra Low fluoroscopic Dose Protocol (ULDP), based on 3.75 frames per second for the fluoroscopy and 7.5 frames per second for the cine acquisition, during CTO PCI. METHODS: One hundred fifty consecutive patients who underwent CTO PCI were retrospectively enrolled. Eighty-five underwent standard dose protocol (SDP) and 65 ULDP. Radiation exposure and acute clinical outcomes were compared between groups. Results were stratified according to lesion complexity. RESULTS: Patients undergoing ULDP, as compared to those undergoing SDP, showed a significant reduction of kerma area product, both for simple lesions (6861.0 vs. 13236.0 mGy × cm2 ; p = 0.014) and complex lesions (CL) (8865.0 vs. 16618.0 mGy × cm2 ; p < 0.001). Similarly, Air Kerma (AK) was lower when ULDP was used (1222.5 vs. 2015.0 cGy in SL, p = 0.134; 1499.0 vs. 2794.0 cGy in CL, p < 0.001). No significant differences were reported regarding procedural success and in-hospital major adverse cardiovascular events between groups. Notably, there was not any crossover from ULDO to SDP due to poor quality images. Interestingly, fluoroscopy time, procedural time and contrast volume was significantly lower in patients undergoing ULDP only for CLs. CONCLUSIONS: ULDP significantly reduces radiation exposure in the setting of high complexity procedures such as CTO PCI. This reduction seemed to be greater with increased procedural complexity and did not impact acute success or adverse clinical events.

RESUMEN

AIM: we sought to test the inter-center reproducibility of 16 echo laboratories involved in the EACVI-Afib Echo Europe. METHODS: This was done on a dedicated setting of 10 patients with sinus rhythm (SR) and 10 with persistent atrial fibrillation (AF), collected by the Principal Investigator. Images and loops of echo-exams were stored and made available for labs. The tested measurements included main echo-Doppler parameters, global longitudinal strain (GLS) and peak atrial longitudinal strain (PALS). RESULTS: Single measures interclass correlation coefficients (ICCs) of left ventricular mass and ejection fraction were suboptimal in both patients with SR and AF. Among diastolic parameters, ICCs of deceleration time were poor, in particular in AF (=.50). ICCs of left atrial size and function, besides optimal in AF, showed an acceptable despite moderate concordance in SR. ICC of GLS was .81 and .78 in SR and AF respectively. ICCs of PALS were suitable but lower in 4-chamber than in 2-chamber view. By depicting the boxplot of the 16 laboratories, GLS distribution was completely homogeneous in SR, whereas GLS of AF and PALS of both SR and AF presented a limited number of outliers. GLS mean ± SE of the 16 labs was 19.7 ± .36 (95% CI: 18.8-20.4) in SR and 16.5 ± .29 (95% CI: 15.9-17.1) in AF, whereas PALS mean ± SE was 43.8 ± .70 (95% CI: 42.3-45.3) and 10.2 ± .32 (95% CI: 9.5-10.9) respectively. CONCLUSION: While the utilization of some standard-echo variables should be discouraged in registries, the application of GLS and PALS could be largely promoted because their superior reproducibility, even in AF.

RESUMEN

Echocardiography is an indispensable tool in the evaluation, placement, management and follow-up of patients with left ventricular assist devices (LVAD). While transoesophageal echocardiography is the ideal tool in guiding the implantation procedure, transthoracic echocardiography is essential during the initial evaluation, patient selection and in the post-operative follow-up. This review attempts to summarize which parameters the echocardiographic assessment should focused on during each step. In particular, during the pre-operative assessment, it is of paramount importance to assess the presence of aortic regurgitation and most importantly to evaluate right ventricular function, since it is one of the strongest predictor of post-implant right ventricular failure. During the procedure, through transoesophageal echocardiography, it is possible to confirm the correct placement of the inflow cannula, to assess right ventricular function and to guide the choice of the right pump speed. Transthoracic echocardiographic is an essential part in the patient's follow-up once the LVAD has been implanted, in order to attest the onset of possible complications.

RESUMEN

Obstructive (OA) and central apneas (CA) are highly prevalent breathing disorders that have a negative impact on cardiac structure and function; while OA promote the development of progressive cardiac alterations that can eventually lead to heart failure (HF), CA are more prevalent once HF ensues. Therefore, the early identification of the deleterious effects of apneas on cardiac function, and the possibility to detect an initial cardiac dysfunction in patients with apneas become relevant. Speckle tracking echocardiography (STE) imaging has become increasingly recognized as a method for the early detection of diastolic and systolic dysfunction, by the evaluation of left atrial and left and right ventricular global longitudinal strain, respectively. A growing body of evidence is available on the alterations of STE in OA, while very little is known with regard to CA. In this review, we discuss the current knowledge and gap of evidence concerning apnea-related STE alterations in the development and progression of HF.

RESUMEN

After initial strategies targeting inotropism and congestion, the neurohormonal interpretative model of heart failure (HF) pathophysiology has set the basis for current pharmacological management of HF, as most of guideline recommended drug classes, including beta-blockers, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and mineralocorticoid receptor antagonists, blunt the activation of detrimental neurohormonal axes, namely sympathetic and renin-angiotensin-aldosterone (RAAS) systems. More recently, sacubitril/valsartan, a first-in-class angiotensin receptor neprilysin inhibitor, combining inhibition of RAAS and potentiation of the counter-regulatory natriuretic peptide system, has been consistently demonstrated to reduce mortality and HF-related hospitalization. A number of novel pharmacological approaches have been tested during the latest years, leading to mixed results. Among them, drugs acting directly at a second messenger level, such as the soluble guanylate cyclase stimulator vericiguat, or other addressing myocardial energetics and mitochondrial function, such as elamipretide or omecamtiv-mecarbil, will likely change the therapeutic management of patients with HF. Sodium glucose cotransporter 2 inhibitors, initially designed for the management of type 2 diabetes mellitus, have been recently demonstrated to improve outcome in HF, although mechanisms of their action on cardiovascular system are yet to be elucidated. Most of these emerging approaches have shifted the therapeutic target from neurohormonal systems to the heart, by improving cardiac contractility, metabolism, fibrosis, inflammation, and remodeling. In the present paper, we review from a pathophysiological perspective current and novel therapeutic strategies in chronic HF.

RESUMEN

Thanks to the improvement in mitral regurgitation (MR) diagnostic and therapeutic management, with the introduction of minimally invasive techniques which have considerably reduced the individual surgical risk, the optimization of the timing for MR "open" or percutaneous surgical treatment has become a main concern which has highly raised scientific interest. In fact, the current indications for intervention in MR, especially in asymptomatic patients, rely on echocardiographic criteria with high severity cut-offs that are fulfilled only when not only mitral valve apparatus but also the cardiac chambers' structure and function are severely impaired, which results in poor benefits for post-operative clinical outcome. This led to the need of new indices to redefine the optimal surgical timing in these patients. Speckle tracking echocardiography provides early markers of cardiac dysfunction due to subtle myocardial impairment; therefore, it could offer pivotal information in this setting. In fact, left ventricular and left atrial strains have already shown evidence about their usefulness in recognizing MR impact not only on symptoms and quality of life but also on cardiovascular events and new-onset atrial fibrillation in these patients. Moreover, right ventricular strain could be used to identify those patients with advanced cardiac damage and different grades of right ventricular dysfunction, which entails higher risks for cardiac surgery that could overweigh surgical benefits. This review aims to describe the importance of reconsidering the timing of intervention in MR and to analyze the potential additive value of speckle tracking echocardiography in this clinical setting.

RESUMEN

Myocardial fibrosis (MF) represents the underlying pathologic condition of many cardiac disease, leading to cardiac dysfunction and heart failure (HF). Biopsy studies have shown the presence of MF in patients with decompensating HF despite apparently normal cardiac function. In fact, basic indices of left ventricular (LV) function, such as LV ejection fraction (EF), fail to recognize subtle LV dysfunction caused by MF. Cardiac magnetic resonance (CMR) with late gadolinium enhancement (LGE) is currently recognized as the gold standard imaging investigation for the detection of focal and diffuse cardiac chambers MF; however, its use is limited by its availability and the use of contrast agents, while echocardiography remains the first level cardiac imaging technique due to its low cost, portability and high accessibility. Advanced echocardiographic techniques, above all speckle-tracking echocardiography (STE), have demonstrated reliability for early detection of structural myocardial abnormalities and for the prediction of prognosis in acute and chronic HF. Myocardial strain of both ventricles and also left atrium has been shown to correlate with the degree of MF, providing useful prognostic information in several diseases, such as HF, cardiomyopathies and valvular heart disease. This paper aims to provide an overview of the pathophysiology of MF and the clinical application of STE for the prediction of left and right heart chambers MF in HF patients.

RESUMEN

Severe mitral regurgitation (MR) is a common valve disease which is associated with high mortality, if only managed medically. MR produces chronic and progressive volume overload with left atrial (LA) and left ventricular (LV) dilatation and dysfunction, atrial fibrillation (AF) and eventually myocardial fibrosis, irrespective of ejection fraction (EF). Surgical correction (mitral valve repair) of MR removes the volume overload, hence unmasks pre-operative LV structure and function disturbances, including reduced EF and global longitudinal and circumferential strain, as well as LA volume and strain. This review aims at describing LA remodeling before and after surgical repair.

RESUMEN

In the last decade, speckle tracking echocardiography (STE) has acquired a fundamental role in the evaluation of the systolic function of the left ventricle, with several advantages over the Doppler method, including angle independence, greater reproducibility, and rapidity of image acquisition. Speckle tracking finds application in various pathologies, ranging from ischaemic heart disease, to cardiomyopathies, to heart failure, both with reduced and preserved ejection fraction (EF), in which the EF is not a reliable prognostic marker and the estimate of left ventricular function by means of 'strain' is of crucial utility. In addition, the strain of the left atrium finds application in many clinical contexts as an early index of diastolic dysfunction and left ventricular filling pressures. Finally, the strain of the right ventricle is of particular prognostic importance in the evaluation of heart failure, particularly in its advanced form, becoming an indispensable index in the evaluation of patients who are candidates for advanced therapeutic strategies. This document aims to describe the various fields of clinical application of STE, with particular emphasis on its diagnostic and prognostic role, so much that it is now integrated into the algorithms for managing multiple pathologies in daily clinical practice.

RESUMEN

Exercise training is highly recommended in current guidelines on primary and secondary prevention of cardiovascular disease (CVD). This is based on the cardiovascular benefits of physical activity and structured exercise, ranging from improving the quality of life to reducing CVD and overall mortality. Therefore, exercise should be treated as a powerful medicine and critical component of the management plan for patients at risk for or diagnosed with CVD. A tailored approach based on the patient's personal and clinical characteristics represents a cornerstone for the benefits of exercise prescription. In this regard, the use of cardiopulmonary exercise testing is well-established for risk stratification, quantification of cardiorespiratory fitness and ventilatory thresholds for a tailored, personalised exercise prescription. The aim of this paper is to provide a practical guidance to clinicians on how to use data from cardiopulmonary exercise testing towards personalised exercise prescriptions for patients at risk of or with CVD.

RESUMEN

BACKGROUND: SARS-CoV-2 infection might be associated with cardiac complications in low-risk populations, such as in competitive athletes. However, data obtained in adults cannot be directly transferred to preadolescents and adolescents who are less susceptible to adverse clinical outcomes and are often asymptomatic. OBJECTIVES: We conducted this prospective multicentre study to describe the incidence of cardiovascular complications following SARS-CoV-2 infection in a large cohort of junior athletes and to examine the effectiveness of a screening protocol for a safe return to play. METHODS: Junior competitive athletes suffering from asymptomatic or mildly symptomatic SARS-CoV-2 infection underwent cardiac screening, including physical examination, 12-lead resting ECG, echocardiogram and exercise ECG testing. Further investigations were performed in cases of abnormal findings. RESULTS: A total of 571 competitive junior athletes (14.3±2.5 years) were evaluated. About half of the population (50.3%) was mildly symptomatic during SARS-CoV-2 infection, and the average duration of symptoms was 4±1 days. Pericardial involvement was found in 3.2% of junior athletes: small pericardial effusion (2.6%), moderate pericardial effusion (0.2%) and pericarditis (0.4%). No relevant arrhythmias or myocardial inflammation was found in subjects with pericardial involvement. Athletes with pericarditis or moderate pericardial effusion were temporarily disqualified, and a gradual return to play was achieved after complete clinical resolution. CONCLUSIONS: The prevalence of cardiac involvement was low in junior athletes after asymptomatic or mild SARS-CoV-2 infection. A screening strategy primarily driven by cardiac symptoms should detect cardiac involvement from SARS-CoV-2 infection in most junior athletes. Systematic echocardiographic screening is not recommended in junior athletes.
