ABSTRACT
Coronary artery ectasia (CAE) is a rare condition, affecting 3%-8% of patients with atherosclerotic coronary artery disease, and is characterized by the abnormal dilatation of the coronary arteries. While the etiology of coronary artery ectasia encompasses a myriad of acquired and genetic factors, its pathogenesis still remains a subject of investigation. The clinical manifestations are varied, ranging from asymptomatic cases to chest angina and myocardial infarction. Coronary angiography remains the gold standard for diagnosing CAE. We herein report four cases of coronary ectasia: the first involving myocardial infarction, the second associated with bicuspid aortic valve with severe aortic regurgitation, the third detected during coronary angiography for moderate left ventricular dysfunction, and the last one detected during coronary angiography for stable angina. The aims of our study are to highlight the diversity of clinical presentations as well as the challenge of management, given that there are no universal treatments or guidelines.
ABSTRACT
We report the case of a 64-year-old patient with a history of coronary artery disease and severe left ventricular dysfunction ischemic requiring medical therapy only admitted for dyspnea. The association of heart failure with COVID-19 pneumonia is discussed. The distinction between these two pathologies is based on a set of clinical, biological and radiological arguments.

Mechanical heart valve thrombosis is not so rare in pregnant women because of the difficulties in managing anticoagulant treatment and the hypercoagulability state associated with pregnancy. Among the embolic complications of valve prosthetic thrombosis, the coronary embolism is rare, it requires an urgent pharmaco-invasive approach which must be adapted to this particular associated condition. We report the observation and the difficulties of managing antithrombotic therapy in a pregnant patient hospitalized for non-obstructive prosthetic valve thrombosis complicated by coronary embolism and resulting in ST elevation myocardial infarction.
