Coronary artery ectasia (CAE) is an entity causing inappropriate dilatation of the coronary tree, that is angiographically defined, albeit arbitrarily, by the diameter of the ectatic segment being more than 1.5 times larger in comparison with an adjacent healthy reference segment. Although the causative mechanisms are poorly understood, atherosclerosis is greatly implicated in the causation of CAE. Clinical, angiographic, and therapeutic features have been puzzling clinicians. We illustrate three different angiographic subsets, co-existing with myocardial bridge/coronary slow flow and diversely presenting as asymptomatic, pauci, and frankly symptomatic with stable and acute coronary syndrome. These cases illuminate the diversity of CAE's clinical and angiographic presentations and pathologic progression, shedding light on this medical condition and its implications.
Background: The coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2 (sarscov2), has been shown to cause conventional respiratory distress, in addition to that, there has been recent reports suggesting the cardiovascular system involvement during the course of the infection, including microthrombosis and cardiopulmonary serosal layers infection and inammation although being separately described. The present paper demonstrates the rst reported case of the concomitant presence of intra-cardiac free- oating microthrombi and pericardial effusion secondary to COVID-19 infection, beyond the casual clinical presentation. Case report :A 51 year-old man with no medical history, presented to the emergency department, with a progressively worsening dyspnea, he had an oxygen saturation of 85% on rst medical contact. The chest radiography and the baseline ECG showed respectively multifocal bilateral patchy opacities and a sinus tachycardia with low QRS voltage and t wave inversion in all leads. On further assessment, the echocardiography revealed the presence of free-oating microthrombi in the right atrium and a moderate pericardial effusion. Biological ndings and pulmonary computed tomography were suggestive of sarscov2 infection. Interestingly, there was no evidence of pulmonary embolism. The patient, thus, received heparin therapy and colchicine. We noted a rapid improvement in the following seven days, the hospital discharge was, hence, deemed warranted. Conclusions: This case highlights an unusual presentation of COVID-19 infection, the diagnostic and therapeutic challenges we are facing in this setting. Moreover, it raises the question about the emergent need of a therapeutic regimen, in order to better manage this unique condition and a fortiori mitigate the COVID-19 complications.
Right heart thrombi can form in situ or lodge in the right cardiac chambers, originating from deep venous thrombosis. The latter carries a poor prognosis, taking into account the very high mortality rate. We herein report a case of an 83-year-old man who developed thrombus in the inferior vena cava that extended up to the right atrium, along with two distinct masses attached to the right ventricle wall.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
