Aims: The athlete's heart in power training is characterized by physiologic concentric remodeling. Our aim was to analyze left ventricular (LV) myocardial deformation and contractile reserve (CR) in top-level power athletes (PA) at rest and during exercise and their possible correlations with functional capacity., Methods: Standard echo, lung ultrasound, and LV 2D speckle-tracking strain were performed at rest and during exercise in PA and in age- and sex-comparable healthy controls., Results: 250 PA (male: 62%; 33.6 ± 4.8 years) and 180 age- and sex-comparable healthy controls were enrolled. LV ejection fraction (EF) at baseline was comparable between the two groups, while LV global longitudinal strain (GLS) was reduced in PA (GLS: -17.8 ± 2.4 in PA vs. -21.9 ± 3.8 in controls; P < 0.01). Conversely, myocardial work efficiency (MWE) did not show significant difference between the two groups (94.4 ± 3.2 in PA vs. 95.9 ± 4.6% in controls; P NS). At peak exertion during exercise stress echocardiography (ESE), PA showed better exercise capacity and peak VO2 consumption (51.6 ± 10.2 in EA vs. 39.8 ± 8.2 mL/Kg/min in controls, P < 0.0001), associated with augmented pulmonary artery systolic pressure (PASP). By multivariable analysis, MWE at rest was the most predictive factor of maximal watts ( P < 0.0001), peak VO2, ( P < 0.0001), PASP ( P < 0.001), and number of B-lines ( P < 0.001), all measured at peak effort., Conclusions: In power athletes, MWE showed less load dependency than GLS. Normal resting values of MWE in PA suggest a physiological LV remodeling, associated with a better exercise capacity and preserved CR during physical stress., Competing Interests: There are no conflicts of interest., (Copyright: © 2022 Journal of Cardiovascular Echography.)

Sudden cardiac death (SCD) of an athlete is a rare but tragic event and sport activity might play a trigger role in athletes with underlying structural or electrical heart diseases. Preparticipation screenings (PPs) have been conceived for the potential to prevent SCD in young athletes by early identification of cardiac diseases. The European Society of Cardiology protocol for PPs includes history collection, physical examination and baseline electrocardiogram, while further examinations are reserved to individuals with abnormalities at first-line evaluation. Nevertheless, transthoracic echocardiography has been hypothesized to have a primary role in the PPs. This review aims to describe how to approach an athlete-focused echocardiogram, highlighting what is crucial to focus on for the different diseases (cardiomyopathies, valvulopathies, congenital heart disease, myocarditis and pericarditis) and when is needed to pay attention to overlap diagnostic zone ("grey zone") with the athlete's heart. Once properly tested, focused echocardiography by sports medicine physicians may become standard practice in larger screening practices, potentially available during first-line evaluation., Competing Interests: Conflict-of-interest statement: The authors declare no conflicts of interest., (©The Author(s) 2021.

Among acute coronary syndrome (ACS) patients, 15% have concomitant cancer, especially in the first 6 months after their diagnosis, as well as in advanced metastatic stages. Lung, gastric, and pancreatic cancers are the most frequent malignancies associated with ACS. Chemotherapy and radiotherapy exert prothrombotic, vasospastic, and proinflammatory actions. The management of cancer patients with ACS is quite challenging: percutaneous revascularization is often underused, and antiplatelet and anticoagulant pharmacological therapy should be individually tailored to the thrombotic risk and to the bleeding complications. Sometimes oncological patients also show different degrees of thrombocytopenia, which further complicates the pharmacological strategies. The aim of this review is to summarize the current evidence regarding the treatment of ACS in cancer patients and to suggest the optimal management and therapy to reduce the risk of adverse coronary events after ACS in this high-risk population.

The integrated clinical, laboratory and ultrasound approach is essential for the diagnosis, evaluation and monitoring of the patient's therapy in coronavirus disease 2019 pneumonia. The ideal imaging approach in this context is not yet well defined. Chest X-ray is characterized by low sensitivity in identifying earlier lung changes. The "bedside" pulmonary ultrasound has an undeniable series of advantages in the patient at high infectious risk and can provide incremental data in the respiratory intensive care for the serial control of the individual patient as well as for the home delivery of the stabilized subjects. Pulmonary computed tomography shows high sensitivity but should not be routinely performed in all patients, because in the first 48 h it can be absolutely negative and in the late phase the imaging findings may not change the therapeutic approach. Echocardiography should be limited to patients with hemodynamic instability to assess ventricular function and pulmonary pressures., Competing Interests: Conflict-of-interest statement: There is no conflict of interest associated with the senior author or any of the other coauthors who contributed their efforts in this manuscript., (©The Author(s) 2020.

Echocardiography is a noninvasive imaging technique useful to provide clinical data regarding physiological adaptations of athlete's heart. Echocardiographic characteristics may be helpful for the clinicians to identify structural cardiac disease, responsible of sudden death during sport activities. The application of echocardiography in preparticipation screening might be essential: it shows high sensitivity and specificity for identification of structural cardiac disease and it is the first-line imagining technique for primary prevention of SCD in athletes. Moreover, new echocardiographic techniques distinguish extreme sport cardiac remodeling from beginning state of cardiomyopathy, as hypertrophic or dilated cardiomyopathy and arrhythmogenic right ventricle dysplasia. The aim of this paper is to review the scientific literature and the clinical knowledge about athlete's heart and main structural heart disease and to describe the rule of echocardiography in primary prevention of SCD in athletes., Competing Interests: There are no conflicts of interest., (Copyright: © 2020 Journal of Cardiovascular Echography.)

Mitral valve prolapse is generally a benign condition characterized by fibromyxomatous changes of the mitral leaflet with displacement into the left atrium and late-systolic regurgitation. Although it is an old clinical entity, it still arouses perplexity in diagnosis and clinical management. Complications, such as mitral regurgitation (MR), atrial fibrillation, congestive heart failure, endocarditis, ventricular arrhythmias, and sudden cardiac death (SCD), have been reported. A large proportion of the overall causes of SCD in young competitive athletes is explained by mitral valve prolapse. Recent studies have shown the fibrosis of the papillary muscles and inferobasal left ventricular wall in mitral valve prolapse, suggesting a possible origin of ventricular fatal arrhythmias. Athletes with mitral valve prolapse and MR should undergo annual evaluations including physical examination, echocardiogram, and exercise stress testing to evaluate the cardiovascular risks of competitive sports and obtain the eligibility. In this setting, multimodality imaging techniques - echocardiography, cardiac magnetic resonance, and cardiac computed tomography - should provide a broad spectrum of information, from diagnosis to clinical management of the major clinical profiles of the disease., Competing Interests: There are no conflicts of interest.

'Athlete's heart' is a common term for the various adaptive changes induced by intensive exercise. Exercise causes alterations of the heart in hemodynamic response to the increased systemic and pulmonary demand during exercise. The understanding of these adaptations is of high importance, since they may overlap with those caused by pathological conditions. Cardiac imaging assessment of the athlete's heart should begin with a complete echocardiographic examination. In recent years classical echocardiographic surveys have been joined by new developments: tissue Doppler imaging, strain rate echocardiography, and real-time 3-dimensional echocardiography. This review paper focuses on the importance of these new echocardiographic techniques in delineating the morphological characteristics and functional properties of the athlete's heart.
