Coronary artery aneurysm (CAA) is characterized by a localized dilation of one or more of the coronary arteries with multiple etiologies, including congenital, acquired, or connected to auto-inflammatory diseases with multiple shapes and classifications. It is usually diagnosed incidentally during coronary imaging and can have variable clinical outcomes, ranging from asymptomatic to sudden cardiac death with a generally poor prognosis. Management of this condition faces a clinical dilemma due to the lack of clear guidelines or randomized trials. Treatment should be individualized based on symptoms, shape, and comorbidities. Herein, we present the case report of a 27-year-old female patient with no prior medical conditions. However, she presented with palpitations, and a compressive mass located over the right atrium was identified in the patient. After undergoing cardiac catheterization and coronary scanning, a giant aneurysm of the sinoatrial branch was detected with an aneurysmal left main that was retrieved surgically with good recovery and postoperative course., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Zayour et al.)

Incidentaloma, a term that embodies the detection of certain problems during the performance of unreasonable investigations, resonates in the medical field. Retroaortic coronary sign is a recently recognized echocardiographic feature of the anomalous coronary artery. It is typically associated with anomalies of the left coronary artery, especially the left circumflex artery. As far as has been monitored, few echocardiographic signs that correlate with this feature have been identified. This feature often remains underdiagnosed on transthoracic echocardiograms due to confusion with artifacts, calcifications, and other cardiac structures. A 45-year-old male patient underwent regular cardiac routine assessment. Retroaortic anomalous coronary (RAC) sign was incidentally detected by transthoracic thoracic echocardiogram; consequently, the retroaortic route of the coronary artery was suspected. Coronary computed tomography angiography was requested to confirm the seen echocardiographic signs. After a 3D reconstruction imaging, the left circumflex retroaortic course was identified with right coronary sinus origin. This case ensures the importance of transthoracic echocardiography as a noninvasive tool in diagnosing anomalous coronary arteries. These anomalies are usually diagnosed by coronary computed tomography angiography and coronary angiography, mainly in the presence of retroaortic coronary sign or "crossed aorta sign.", Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Khatoun et al.)

Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-COV-2). Patients with COVID-19 typically present with symptoms and signs related to respiratory tract infection. However, a broad spectrum of cardiac manifestations including myocarditis has been reported as complications of this virus. Nevertheless, focal myocarditis as the first clinical manifestation of COVID-19 infection has not been reported before. Thus, we herein present the case of a 56-year-old male patient previously healthy and presented to the emergency department with chest pain. The clinical picture was compatible with inferior ST-elevation myocardial infarction (STEMI). Initial COVID-19 polymerase chain reaction (PCR) was negative, as well for its classic symptoms. Thereafter, further investigations suggested the diagnosis of focal myocarditis. Later on, the patient started to have a fever and repeated COVID-19 PCR that returned positive., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Zayour et al.)

Epipericardial or epicardial fat necrosis (EFN) is a self-limited inflammatory process occurring in the mediastinal fat surrounding the heart. It is an uncommon cause of acute chest pain and mimics more critical clinical disorders such as acute coronary syndrome, aortic dissection, and pulmonary embolism. However, EFN is frequently overlooked and under-recognized in emergency departments (EDs) owing to the unfamiliarity of this condition among physicians and radiologists. Herein, we present the case of a previously healthy young male patient, with a recent history of mild COVID-19 infection (two weeks before presentation), who presented to the ED for acute chest pain. Paraclinical evaluation including computed tomography (CT) of the chest revealed fat stranding along with the left epicardial fat pad in favor of EFN., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Zayour et al.)
