Abstract
Lymphocytic fulminant myocarditis results in severe myocardial damage that is irreversible in some patients. In these patients, mechanical circulatory support, as the main treatment, is difficult. We describe a patient with a myocarditis-associated arrested heart who underwent successful left ventricular assist device implantation and extracardiac total cavopulmonary connection (EC-TCPC). EC-TCPC was chosen after fluid dynamics simulation was performed using computational fluid dynamics analysis of blood flow. In the analysis, EC-TCPC was compared with the Glenn procedure and the classic Fontan procedure; EC-TCPC had the best performance.
