Objetivo

Evaluar los resultados a medio plazo del cierre percutá-neo de la comunicación interauricular (CIA).

Métodos

Bajo anestesia general se procedió por vía anterógrada al intento de cierre percutáneo de la CIA tipoostium se-cundum en 22niños. La edad fue de 5,7 ±2,4 años y el peso 23 ±11 kg. El procedimiento se monitorizó median-te ecocardiografía transesofágica (ETE). Los dispositivos utilizados fueron DAS-Angel Wings ®y Amplatzer®.

Resultados

Hemodinámicos: presión arterial pulmonar 13 ±2,8 mmHg, resistencias pulmonares, 1,3 ±0,3 U/m 2y Qp/Qs 2,2 ±0,6. El diámetro del defecto por ETE fue de 14,5 ±6,3 mm y por oclusión con balón de 15,9 m 25,3 mm. Se emplearon 31dispositivos, 27Amplatzer ®y 4 DAS-Angel W ings®. Se retiraron sin dificultad 12dispositivos Amplat-zer ®a través de su introductor, cinco por discrepancia con el tamaño de la aurícula izquierda, cuatro por no estabili-zarse en el tabique al ser demasiado pequeños y tres por apertura defectuosa en la aurícula izquierda. En 19 pacien-tes el dispositivo se implantó de forma correcta. La eco-cardiografía transtorácica con Doppler color realizada a las 24 h demostró ausencia de cortocircuito 17 y en todos al mes de la implantación. Los niños fueron dados de alta a las 38±12 h y en el seguimiento de 15±6 meses no se han producido complicaciones, fracturas de la estructura, ni se han demostrado cortocircuitos residuales.

Conclusión

Mediante cierre percutáneo se consiguió una elevada tasa de cierre sin cortocircuito residual cuando se realize una adecuada selección de los pacientes.

Objective

To evaluate the medium-term results of percutaneous closure of atrial septal defect.

Methods

Twenty-two children (mean weight, 23±11 kg; mean age, 5.7±2.4 years) underwent percutaneous atrial septal defect closure under general anesthesia. The procedure was monitored by transesophageal echocardiography. DAS-Angel Wings™ (n=4) and the Amplatzer™ device (n=18) were used.

Results

Mean pulmonary artery pressure was 13±2.8 mmHg, mean pulmonary vascular resistance was 1.5±0.5U/m 2 and mean Qp/Qs flow ratio was 2.2±0.6. The mean diameter of the defects was 14.5±6.3 mm by transesophageal echocar-diography OmniPlane measurement and 15.9±5.3 m m using balloon occlusion reference. Atotal of 31devices were used: 4Angel Wings™ and 27Amplatzer™ devices. Twelve Amplatzer™ devices were withdrawn through the introdu-cer without complications, 5due to a discrepancy in the size of the left auricle, 4because they were too small to stabilize in the septum and 3due to defective opening in the left auri-cle. In 19patients implantation was successful. In 17patients transthoracic color Doppler echocardiography carried out 24hours after the procedure showed a minimal shunt which was no longer present 1month later. The mean time of dis-charge was 38±12 hours after the procedure. After a mean follow up 1566months the patients remain asymptomatic with no clinical or technical problems.

Conclusion

The success rate of percutaneous closure of atrial septal defects in well-selected patients was high and presented no complications.
