Fechamento Percutâneo da Comunicação Interatrial

Abstract: A comunicação interatrial como lesão isolada representa 7% de todas as anomalias congênitas do coração e tem grande predomínio no sexo feminino, cerca de dois terços. Sendo um defeito situado ao longo do septo interatrial é fá-cil compreender que sua localização é variável. Consideramse quatro tipos anatômicos principais: 1) o tipo mais freqüente, o ostium secundum ou da fossa oval, corresponde a 75% dos casos, podendo ser um defeito único, múltiplo ou apresentar-se com fossa oval multifenestrada; 2) o tipo os… Show more

“…As a general rule, the diameter of the occluder should be around 1.7 to 2 times the stretched diameter. Although the determination of the stretched diameter is important for selecting the appropriate Helex, it is not as crucial as it is with the Amplatzer 10,14 , where its occlusive mechanism and its stability in the septum are dependent on its central portion, which is effectively inside the atrial septal defect and which must have a similar diameter to that stretched. The correlation between the size of the atrial septal defect in transesophageal echocardiography and the size of its stretched diameter depends on distensibility of the atrial septum, which may vary.…”

“…In patients with patent foramen ovale, angiography and collection of samples for oximetry were not performed. The stretched diameter was determined only in patients with atrial septal defects, using sizing balloons (AGA Medical Corporation) (24mm) with techniques similar to those already described [8][9][10][11][12][13][14] . After determining the stretched diameter, the devices were selected and placed, following the steps described above.…”
