“…Most children with atrial septal defect are asymptomatic or exhibit mild symptoms, and thus percutaneous closure tends to be postponed until 4 years of age or until reaching more than 15 kg of weight, due to the high rate of spontaneous closure of defects smaller than 8 mm within the first years of life 1,2 . Some patients with a large left-to-right shunt experience failure to thrive, repeated lower respiratory tract infections or asthma attack episodes with multiple hospitalizations, and in this cases, closure of the defect would be indicated despite weight and age, mainly in those with a history of prematurity or chromosomal abnormalities.…”

“…Consequently, the usual closure technique tends to fail in most these cases. Sharma et al 2 published a study with 45 pediatric patients, with a mean of 25 months of age and average weight of 8.9 kg, in whom the usual release technique was effective only in 15 patients, with special release maneuvers being required in 28 patients; the most commonly used was the release into the left superior pulmonary vein, with 18 cases, followed by the balloon-assisted technique in six cases, release into the right superior pulmonary vein in three cases and release into the left appendage in one case. The balloon-assisted technique has the disadvantage of requiring another venous vascular access, an additional operator to hold the balloon, and longer procedure and hemostasis time 3 .…”

“…La mayoría de los niños con comunicación interauricular son asintomáticos o presentan síntomas leves, por lo que el cierre percutáneo se tiende a aplazar hasta los 4 años de edad o con un pesos superior a 15 kg; lo anterior, debido a la alta tasa de cierre espontáneo de los defectos menores de 8 mm en los primeros años de vida 1 , 2 . Algunos pacientes con gran cortocircuito de izquierda a derecha presentan falla de medro, infecciones de vías respiratorias bajas de repetición o episodios de crisis asmáticas con múltiples hospitalizaciones, por lo que estaría indicado el cierre del defecto a pesar del peso y la edad principalmente en aquellos con antecedente de prematuridad o cromosomopatías.…”

“…Por lo anterior, la técnica de cierre habitual tiende a fallar en la mayoría de los casos. Sharma, et al 2 publicaron un estudio con 45 pacientes pediátricos, con una media de 25 meses edad y un peso promedio de 8.9 kg, en los que la técnica de liberación habitual solo fue efectiva en 15 pacientes, requiriendo maniobras especiales de liberación 28 pacientes; la más frecuentemente usada fue la liberación en la vena pulmonar superior izquierda, con 18 casos, seguida por la técnica asistida con balón en seis casos, la liberación en la vena pulmonar superior derecha en tres casos y la liberación en la orejuela izquierda en un caso. La técnica asistida con balón tiene la desventaja de requerir otro acceso vascular venoso, un operador adicional para sostener el balón, y mayor tiempo de procedimiento y de hemostasia 3 .…”

“…Of course, there are recent reports for transcatheter closure of ASD that showed excellent short and long-term results in less than 2 years old and 10 kg patients. 7) 8) That is, meticulous evaluation of morphology for ASD and its adjacent structure, well-prepared and delicate procedure, and some special techniques as like balloon-assisted or pulmonary vein technique can make the transcatheter closure safe and feasible in early childhood.…”
