Abstract:
Isolated manifestation of sarcoidosis in the heart is very rare. The present work describes the case of a 41-year-old woman with ventricular tachycardia and severe symptoms of heart failure in June 2006. Clinical, MRI and echocardiographic findings revealed the diagnosis of an arrhythmogenic right ventricular dysplasia. Due to the severe progression of the disease, cardiac transplantation was performed in August 2007. Histopathological examination of the explanted heart, however, revealed numerous non-necrotising granulomas with giant cells, lymphocytic infiltration and interstitial fibrosis, finally confirming the diagnosis of a myocardial sarcoidosis.
