چکیده
A 6-year-old girl had cold-like symptoms. Administration of antibiotics did not improve the symptoms, and the patient had chronic chest pain. Electrocardiogram (ECG) demonstrated ventricular tachycardia (VT) and cardiac enzyme levels were increased. Mexiletine and olprinone were continuously administered, but slow VT and III degrees A-V block repeatedly occurred. Pulse therapy using methyl prednisolone was performed, but hemodynamics did not improve. Ejection fraction (EF) decreased to 20%, and metabolic acidosis occurred. Extra corporeal membrane oxygenation (ECMO) was applied 24 hours after admission to the intensive care unit (ICU). To apply ECMO, a median sternotomy was performed. An in-flow cannula (15 Fr) was inserted into the ascending aorta and an out-flow cannula (19 Fr) was inserted into the right atrium. After returning to the ICU, blood pressure (BP) were stable, and urine volume was maintained at about 100 ml/h. Methyl prednisolone and gamma-globulin were administered during circulatory assisted period. About 24 hours later, sinus rhythm was obtained, and weaning was started after improvement of the EF. BP was maintained at 100 mmHg with low dose catecholamine, which was weaned off 42 hours after commencement. Hemodynamics after this remained stable. EF improved to 54.2%. An ECG demonstrated right bundle branch block (RBBB) at the sinus rhythm. Severe inflammatory changes were pathologically observed, and we diagnosed myocarditis. The patient was discharged from the hospital on 43 days post admission, and currently attends school.

We report a case of successfully treated acute fulminant myocarditis induced by ulcerative colitis with extracorporeal life support and infliximab. Myocarditis is a rare but crucial complication during an exacerbation of inflammatory bowel disease. In our case, we applied extracorporeal membrane oxygenation (ECMO) for cardiac rest under impression of acute myocarditis associated with ulcerative...
متن کاملA Case of Reversible Very Low Voltage Electrocardiogram in Fulminant Myocarditis
Clinical features of acute myocarditis range from a subclinical state to a fulminant state. Fulminant myocarditis with ventricular arrhythmia or atrioventricular block is associated with a high mortality rate. In cases in which aggressive medical therapy for fulminant myocarditis is not likely to be successful, intensive and emergency mechanical circulatory support, such as extracorporeal membr...

BACKGROUND Peripheral venoarterial extracorporeal membranous oxygenation (ECMO) support is effective in patients with cardiogenic shock or fatal arrhythmia due to fulminant myocarditis. The clinical courses of fulminant myocarditis are still uncertain; therefore, it is difficult to determine the appropriate time for discontinuing ECMO or converting to a ventricular assist device. The purpose of...
