Experiência inicial no fechamento percutâneo da comunicação interatrial tipo ostium secundum com a prótese figulla / Initial experience in the percutaneous occlusion of ostium secundum atrial septal defect with the Figulla device

RESUMO

INTRODUÇÃO: O tratamento percutâneo da comunicação interatrial tipo ostium secundum é a modalidade terapêutica de escolha em mais de 80 por cento dos casos. Várias próteses encontram-se disponíveis pra tal finalidade. Relatamos nossa experiência com a oclusão percutânea da comunicação interatrial com a prótese Figulla (Occlutech, Praga, República Tcheca), avaliando a segurança e a eficácia do método. Método: De abril de 2008 a março de 2010, foram realizados 25 procedimentos em dois centros de referência em 25 pacientes não-consecutivos (mediana de idade de 22 anos e de peso de 60 kg) sob anestesia geral e monitoração pela ecocardiografia transesofagica. Do total de comunicações interatriais, 23 eram únicas, com diâmetro...

ABSTRACT

BACKGROUND: Percutaneous treatment of ostium secundum atrial septal defect is the preferred therapy in over 80% of cases. Several devices are available for this purpose. We report our experience with the percutaneous closure of atrial septal defect with the Figulla device (Occlutech, Prague, Czech Republic) assessing the safety and efficacy of the procedure. METHOD: From April 2008 to March 2010, 25 procedures were performed in 2 reference centers in 25 non-consecutive patients (median age 22 years and median weight 60 kg) under general anesthesia and transesophageal echocardiographic monitoring. Atrial septal defects were single in 23 cases and multiple in 2 cases and had a mean diameter of 17.5 ± 9.4 mm. In one patient it was necessary to use two devices in two distant atrial septal defects. The mean diameter of the devices was 20.8 ± 7.4 mm and they were implanted through 9-14 F long sheaths in the femoral vein. RESULTS: Successful implantation was observed in all cases. In one case, there was embolization immediately after device release. The device was retrieved from the descending aorta followed by implantation of a new device. The mean follow-up was 12 months and the occlusion rate was 100%. There were no late complications. CONCLUSION: In this initial experience, percutaneous occlusion of the atrial septal defect with the Figulla device was easy to perform, safe and highly effective.
