Successful treatment of tetralogy of Fallot with pulmonary atresia using a pulmonary homograft.

A 13-year-old boy with tetralogy of Fallot and pulmonary atresia after a Waterston and Blalock-Taussig shunt underwent successful repair using a cryopreserved pulmonary homograft as a valved extracardiac conduit. Aortic transection gave a good operative field for pulmonary angioplasty and closure of the Waterston anastomosis. The cryopreserved pulmonary homograft provided excellent handling characteristics.

[Congenital pulmonary arteriovenous fistula. Apropos of 2 cases].

The authors discuss echocardiographic diagnosis and endovascular treatment of two different anatomical types of pulmonary arteriovenous fistula. Transoesophageal echocardiography in a cyanotic 3 year old boy revealed a direct right pulmonary artery left atrial fistula, treated by surgical ligation of the anomalous feeding artery. A cerebral abscess in a 22 year old man with hereditary haemorrhagic telangiectasia revealed pulmonary and cerebral arteriovenous malformations, which were both treated successfully by embolization.

Systemic-pulmonary shunt with a right retroesophageal subclavian artery.

A 19-day-old child suffering from cyanosis due to tetralogy of Fallot was palliated by using his right retroesophageal subclavian artery. It was anastomosed side-to-side onto the ascending aorta and end-to-side onto the right pulmonary artery. The palliation obtained with this systemic-pulmonary shunt was satisfying.
