title: Echocardiographic assessment of a Blalock-Taussig shunt.
abstract: A case of echocardiographic confirmation of the patency of a Blalock-Taussig anastomosis is presented. Using the left atrium-to-aortic ratio (LA/Ao), we could document an increase in left atrial size representing an increase in pulmonary blood flow. This is the first report using echocardiography to prove the patency of a systemic-to-pulmonary artery anastomosis.
