Bidimensional real-time echocardiological visualization of a ventricular right-to-left shunt following peripheral vein injection.
Eur J Cardiol. 1977; 6(2):99-107 (ISSN: 0301-4711)

Contrast techniques were used in the echocardiological evaluation of a 28-yr-old patient with congenital cyanotic heart disease; catheterization showed an association of an atrial septum defect, a ventricular septum defect, and a patent ductus arteriosus, with equalization of pulmonary artery and systemic pressures. Glucose 5% in water, injected as a 10-ml bolus into an antecubital vein, constituted an adequate echogenic contrast solution. The heart was examined with both a single-crystal transducer (echoes recorded in M mode) and with a 51-elements dynamically focuses multiscan system (echoes recorded on video-tape). Contrast echocardiology showed that right-to-left shunting occurred at the level of the ventricular septum defect and was not significant at the atrial level.
