[Echocardiographic diagnosis of a thrombus in the pulmonary artery following a banding operation]

Abstract

In an infant with univentricular heart and banding of the pulmonary artery a thrombus developed in the pulmonary artery distal to the banding. The diagnosis was made at first by two-dimensional echocardiography and confirmed by angiography. The pathogenetic factors and the clinical relevance of this rare observation are discussed.
