Circumferential extent of thinning of the basal muscular ventricular septum in a case of cardiac sarcoidosis
Abstract
Focal thinning of the basal muscular ventricular septum is a characteristic morphological finding in cases of cardiac sarcoidosis, usually detected on the parasternal long-axis image during echocardiography. Surprisingly, however, its circumferential extent has rarely been demonstrated and discussed. We present a case showing typical thinning of the basal ventricular septum. The extent of circumferential wall thinning was evaluated using both echocardiography and cardiac computed tomography. The present case highlights the importance of detailed multiplanar and three-dimensional evaluation of this characteristic abnormality, more so because its mechanism as well as the precise impact on conduction has not yet been elucidated.
