Abstract 10972: Transthoracic Echocardiography-guided Percutaneous Patent Ductus Arteriosus Occlusion: A New Strategy For Interventional Treatment
Objectives: This prospective single center study investigated the safety and efficacy of percutaneous patent ductus arteriosus (PDA) occlusion using the Amplatzer Duct Occluder II (ADO II) under only guidance of transthoracic echocardiography, which avoids the radiation and contrast agents of traditional PDA occlusion.
Methods: From June 2013 to February 2015, 54 consecutive PDA patients (age, 4.6 ± 2.9 years; weight, 18.5 ± 7.5 kg; PDA narrowest diameter, 3.3 ± 1.1 mm) underwent transthoracic echocardiography guided PDA occlusion through the femoral artery. Outpatient follow-up was conducted at 1, 3, and 6 months, and yearly.
Results: Echocardiography-guided percutaneous PDA occlusion was successfully performed in 53 patients. The procedure was converted to minimally invasive transthoracic occlusion in one patient due to failure of delivery catheter passage through tortuous PDA. Mean procedure duration was 25.5 ± 7.4 minutes; ADO II diameter averaged 4.7 ± 0.9 mm; 8 cases showed traces of residual shunt immediately after operation; and mean hospital stay was 3.4 ± 0.7 days. There was no occluder migration, hemolysis or pericardial effusion at mean 10.2±4.9 months follow-up.
Conclusions: Percutaneous PDA occlusion under only guidance of transthoracic echocardiography appears safe and effective while avoiding radiation and contrast agent use.
Legends: A) A suprasternal view showed the tip of pigtail catheter (arrow) faced the aortic end of the PDA. B) The left parasternal long axis view of the pulmonary artery showed that the guide wire (arrow) was located within the main pulmonary artery. C) The release of the occluder at the pulmonary side (arrow). D) The occluder was completely released (arrows point to each side of the occluder). PDA, patent ductus arteriosus; DAO, descending aorta; PA, pulmonary artery; AO, ascending aorta.
