Abstract
We present a patient with non-cardiac sarcoidosis complicated with manifest ventricular preexcitation. Initially, cardiac involvement of sarcoidosis was suspected from the echocardiographic findings showing localized hypokinesia at the left ventricular basal inferior wall. We, however, considered that the hypokinesia was a preexcitation-induced mechanical dyssynchrony rather than cardiac sarcoidosis, because polarities of the delta-waves indicated a left ventricular inferior accessory pathway. Temporal administration of oral flecainide acetate eliminated the basal left ventricular motion abnormality. Accordingly, we could successfully differentiate the mechanism of hypokinesia. In this context, we could rule out cardiac sarcoidosis, and initiation of glucocorticoid therapy was reasonably withheld.
