title: The value of contrast echocardiography in the diagnosis of patent ductus arteriosus with Eisenmenger's syndrome.
abstract: When patent ductus arteriosus (PDA) is complicated by pulmonary hypertension resulting in a right-to-left shunt, an erroneous diagnosis of primary pulmonary hypertension may be made, even after echocardiographic examination. Among the 8 patients referred to our echocardiography laboratory with the diagnosis of primary pulmonary hypertension between June 1994 and November 1999, 2 patients were found to have PDA with Eisenmenger's syndrome. Patent ductus arteriosus with Eisenmenger's syndrome can be diagnosed by the opacification of the abdominal aorta without opacification of the left-sided chambers during contrast echocardiography.
