Tako-Tsubo Syndrome Triggered by a Fibroscopy: Case Report.

Tako-Tsubo cardiomyopathy, also called stress cardiopathy, is a rare syndrome characterized by transient regional systolic dysfunction. It can mimic myocardial infarction but the absence of coronary obstruction allows to redress the diagnosis. Its pathogenesis is not well understood. However, the role of physical or emotional stress has often been associated with this pathology. Here we report, a rare case of a 63-year-old female, with no cardiac risk factors, who presented Tako-Tsubo syndrome after a fibroscopy. This case aims to show that Tako-Tsubo syndrome should be suspected in patients, especially women, with no cardiac risk factors, who present acute chest pain in the context of physical or emotional stress, after excluding differential diagnoses.

Post-vaccine COVID-19 acute myocarditis: case reports and literature review.

COVID-19 vaccines have reduced both lethality and hospitalization rates of the novel coronavirus disease. Nevertheless, multiple side effects have been reported in the literature, most often are harmless. We report two cases of acute myocarditis, hospitalized in the emergency department for chest pain occurring after the second dose of mRNA vaccine AstraZeneca. The SARS-Cov-2 infection was ruled out in both patients with a negative PCR obtained by nasal swabs and normal thoracic CT scans. Both patients had high levels of high-sensitive cardiac troponin I. Acute coronary syndromes were excluded with cardiac catheterization. Cardiac Magnetic resonance imaging (MRI) showed signs in favor of acute myocarditis. The evolution was favorable for both patients after being put on anti-inflammatory treatment. The universality and accumulation of reports concerning acute myocarditis following COVID vaccination, in the absence of any other diagnostic element that could explain the myocardial injury, establish a strong causal link, although the etiopathogenesis of such injury remains poorly elucidated.

Post-COVID myocarditis simulating acute coronary syndrome: Case report.

Acute myocarditis corresponds to an acute inflammation of the myocardium whose origin is most often viral. Several viruses can be incriminated to note the parvovirus B19, the virus herpes of the group 6 and to a lesser degree the virus of the hepatitis C (VHC). Since 2019 and with the discovery of SARS COV2 some cases of myocarditis associated with COVID have been noted, this last association is rare and is present in only 5% of cases. The diagnosis of myocarditis is sometimes difficult and can lead to confusion with acute coronary syndrome, especially in cases of ST-segment elevation on the EKG, hence the interest of magnetic resonance imaging, which has made it possible in recent years to reduce the rate of unnecessary coronary angiography, especially in the case of young subjects with no cardiovascular risk factors. Here, we report the case of a 33-year-old patient with no cardiovascular risk factors and no medical or surgical antecedents who was admitted to the emergency department for the management of acute chest pain, the patient had initially undergone an electrocardiogram which showed an ST-segment elevation in the inferior territory and in the low lateral territory with a mirror image in the high lateral territory. In view of the typical character of the pain and based on the electrical data, it was decided to carry out a coronary angiography which came back without any particularity. As part of the etiological work-up, an MRI scan was performed, which showed an appearance compatible with viral myocarditis. This case shows diagnostic difficulties and management of this disease.
