[Symptomatic atrial fibrillation revealing chronic constrictive pericarditis in a young patient: A case report with a review of the literature].

Chronic Constrictive pericarditis (CCP) is a rare clinical entity that can pose diagnostic problems. Constrictive pericarditis is the final stage of a chronic inflammatory process characterized by fibrous thickening and calcification of the pericardium that impairs diastolic filling, reduces cardiac output, and ultimately leads to right heart failure and to atrial dilatation which can caused supravetricular arrythmia. Transthoracic echocardiography, computed tomography, and cardiac magnetic resonance imaging each can reveal severe diastolic dysfunction, increased pericardial thickness and calcifications.

Late pulmonary embolism in a patient with non-severe COVID-19: case report, value of antithrombotic prophylaxis and literature review.

Since the onset of the COVID-19 pandemic, several small cohorts have reported the recurrent occurrence of venous thromboembolic disease (VTE), particulary pulmonary embolism, in serious patients hospitalized in intensive care units. We report the case of a patient who presented a minor COVID-19 infection treated on an outpatient basis with good clinical resolution. She developed a pulmonary embolism three weeks after the onset of symptoms.
