title: [Percutaneous closure of the inter-auricular communications, well defined indications].
abstract: POSSIBLITIES FOR PROGNOSTIC IMPROVEMENT: The inter-auricular communication (IAC) is the most frequent of congential malformations in adults and is responsible for enhanced morbidity and rduction in life expectancy. The closure of an IAC with volumic overload eradicates such morbidity and mortality. The technical progress in the conception of prosthesises that obstrue the interauricular communications via the percutaneous route make this technique a reliable alternative to surgery that, itself, leads to a certain degree of discomfort and considerable morbidity. DEPENDING ON THE ECHOCARDIOGRAPHICAL DATA: The selection of patients is crucial and relies on trans-thoracic echocardiography. It is indicated in isolated ostium secundum-type inter-auricular communications with a border of at least 4 mm separating it from the adjacent structures of the heart; the size on the echocardiography must not exceed 30 mm. FROM A TECHNICAL POINT OF VIEW: The closure is made under fluoroscopic and echocardiographic control via the trans-oesophageal route. It is rapid, simple, and induces a low rate of morbidity. With Amplatz's prosthesis, the percentage of complete closure is equivalent to that obtained with surgery but with less morbidity with regard to arrhythmia. Today the reliable percutaneous closure of an IAC will probably permit the extension of the indications for the closure of this congenital abnormality in adults.
