Background: There is a paucity of data on cardiovascular sequelae of asymptomatic/mildly symptomatic SARS-Cov-2 infections (COVID).
Objectives: The aim of this prospective study was to characterize the cardiovascular sequelae of asymptomatic/mildly symptomatic COVID-19 among high/elite-level athletes.
Methods: 950 athletes (779 professional French National Rugby League (F-NRL) players; 171 student athletes) were included.
Background: Pathological T-wave inversion (PTWI) is rarely observed on the ECG of healthy athletes, whereas it is common in patients with certain cardiac diseases. All ECG interpretation guidelines for use within athletes state that PTWI (except in leads aVR, III and V1 and in V1-V4 when preceded by domed ST segment in asymptomatic Afro-Caribbean athletes only) cannot be considered a physiological adaptation. The aims of the present study were to prospectively determine the prevalence of cardiac pathology in athletes presenting with PTWI, and to examine the efficacy of cardiac magnetic resonance in the work-up battery of further examinations.

NT-proBNP was previously reported to be usually normal in healthy athletes, but often elevated in case of hypertrophic cardiomyopathy.
Objectives: To assess the interest of NT-proBNP in differential diagnosis of left ventricular hypertrophy in athletes.
Introduction: Septicaemia on endocardial pacemaker leads is very rare but the presentation is insidious and the prognosis very bad if all the implanted materiel is not completely removed.
Observation: A 55 year-old woman presented three episodes of Staphylococcus epidermidis septicaemia in three years, after incomplete removal of the pacing system. Permanent cure was finally obtained after complete removal of the pacemaker material.
