Follow-up electrocardiogram showed ST-segment change improvement over the course.
He was referred to our hospital two weeks later. At the present time, treatment with immunosuppressant drugs is favored by various investigators. When pediatricians encounter patients with suspicion of acute myocardial ischemia, normal coronary anatomy without underlying disease, such as Kawasaki disease, suggest that they are diagnosed as acute myocarditis.
The occurrence of a complete intermittent AV block that did not require electrical stimulation was noted. The authors indicated the difficulty in evaluating these results, as given the normally fatal course of these patients, only those who have survived for some time without treatment would have the opportunity to receive treatment, creating a bias in the selection of survivors.Anatomopathologic macroscopic study of the explanted heart Figure 3 revealed slight dilatation of both ventricles with replacement of the normal muscle tissue of the basal third of the septum, anterior and lateral walls of the left ventricle, and to a lesser degree of the posterior wall of the left ventricle; the ventricles were scarred in appearance and grayish-brown in color, while the apical third of the heart appeared to be preserved practically in its entirety. Clinical and radiological findings revealed acute pulmonary edema. Case Presentation: A year-old young man with a history of asthma presented to the pulmonary department of our hospital with dyspnea, left sided chest pain, cough, wheezing. Asthma was diagnosed and treated, however his respiratory complaints have persisted. Chest x-ray showed acute pulmonary edema. In this study, a case of viral myocarditis in a patient with acute retrosternal pain, elevated cardiac markers and electrocardiographic ST-T changes similar to the clinical presentation of myocardial infarction is presented. Myocarditis associated with influenza B virus seemed to be caused by endothelial impairment and disturbance of microcirculation rather than direct injury to cardiac myocytes. This article has been cited by other articles in PMC. The macroscopic changes had a slight effect on the anterior face of the right ventricle. He went to the emergency room the following morning due to a pre-syncopal episode. The occurrence of a complete intermittent AV block that did not require electrical stimulation was noted. Correspondence: Dr. He had febrile illness and diarrhea for the past 2 days. It can be seen that muscle tissue has been replaced by scar tissue in large areas of both ventricles, particularly in the septum and anterior and lateral walls of the left ventricle; nevertheless, the muscle is preserved in most apical portions, corresponding to findings on ventriculography.
In the Stanford series,7 the 5 cases developed progressive cardiac insufficiency and ventricular tachycardia. Histological examination Figure 4 revealed an intense inflammatory infiltrate of lymphocytes and plasma cells, with some eosinofils and abundant multinucleated giant cells.
The patient underwent immediate coronary angiography, which revealed normal coronary arteries.
