We present a patient with Ebstein anomaly who underwent surgical tricuspid valve replacement and suffered early valve stenosis due to her unique anatomy. This case highlights the importance of the "unnatural" anatomy that can be encounter in this challenging patient population. Recently, data from temporal dispersion of myocardial repolarization analysis have gained a capital role in the sudden cardiac death risk stratification. Aim of this study was to evaluate the influence of heart rate, autonomic nervous system, and controlled breathing on different myocardial repolarization markers in healthy subjects. Myocardial repolarization dispersion markers from short-period (5 minutes) electrocardiogram (ECG) analysis (time and frequency domain) have been obtained in 21 healthy volunteers during the following conditions free breathing (rest); controlled breathing (resp); the first 5 minutes of postexercise recovery phases (exercise ), maximum sympathetic activation; and during the second 5 minutes of postexercise recovery phases (exercise ), intermediate sympathetic activation. Finally, we analyzed the whole repolarization (QTe), the QT peak (QTp), and T peak - T end intervals (Te). During the exercise , major part of repolarization variables changed in comparison to the restbjects, whereas they do not alter any spectral components. Cardiovascular complications related to coronavirus disease 2019 (COVID-19) have led to the need for echocardiographic services during the pandemic. The present study aimed to identify the echocardiographic findings in hospitalized COVID-19 patients and their utility in disease management. We included patients who were diagnosed with COVID-19 using polymerase chain reaction and those who underwent echocardiographic examination during their hospitalization. Altogether,
