Safety and efficacy of percutaneous transcatheter closure of atrial septal defect under transesophageal echocardiography guidance in children / 中华心血管病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To assess the safety and effectiveness of percutaneous transcatheter closure of atrial septal defect (ASD) under transesophageal echocardiography (TEE) guidance in children.</p><p><b>METHODS</b>The study included 20 cases of patients with ASD. The patients were (4.2 ± 1.2) years old and the mean body weights were (18.2 ± 4.2) kg. The diameter of ASD before closure was (13.4 ± 3.3) mm . All procedures were guided under TEE. Procedure success was evaluated by TEE immediately after procedure.</p><p><b>RESULTS</b>Closure devices were successfully implanted in all 20 patients under TEE guidance. The diameter of closure devices was 14-26 mm. There were no procedure related complications. The ventilation time was (2.9 ± 0.8)h and the hospitalization time was (3.2 ± 0.7) days.</p><p><b>CONCLUSION</b>TEE guided percutaneous transcatheter closure is safe and effective for patients with ASD and avoids the radiation damages.</p>
