Live Three‐Dimensional Transthoracic Echocardiographic Assessment of Left Ventricular Hydatid Cyst

Abstract

We report an adult patient in whom live three-dimensional transthoracic echocardiography (3DTTE) complemented two-dimensional transthoracic echocardiography (2DTTE) in making a definitive diagnosis of a hydatid cyst located in the left ventricular cavity. The parent hydatid cyst, as well as the daughter cysts, contained within it could be delineated by both 2DTTE and live 3DTTE. However, the tertiary or granddaughter cysts originating from the daughter cysts as well as great-granddaughter cysts budding from tertiary cysts could be visualized only when the live 3DTTE data sets were cropped and sectioned sequentially using multiple cutting planes. In addition, apparent intrinsic mobility of some of the tertiary cysts implying viability was detected only by 3DTTE.
