Echocardiogram-gated multislice spiral CT in functionally univentricular heart following long-lasting Waterston-Cooley anastomosis.

ABSTRACT

Waterston-Cooley anastomosis may be carried out in patients with tricuspid atresia to provide pulmonary perfusion. It is associated with several complications, including preferential blood flow to the right lung, hypoplasia of the left pulmonary artery, obstruction of the anatomosis or rupture of pulmonary aneurysms. We study a patient with thrombosis in the pulmonary arteries following surgical construction of a Waterston shunt in childhood. Imaging findings and clinical symptoms are discussed with emphasis on echocardiogram-gated multislice spiral CT.
