n Cardiovascular Journal of Africa - Ductal closure using the Amplatzer duct occluder type two : experience in Port Elizabeth hospital complex, South Africa : cardiovascular topic
Objective : To report outcomes in percutaneous ductal closure using the Amplatzer duct occluder type two (ADO II).
Methods : Records of patients admitted for percutaneous closure of patent ductus arteriosus (PDA) were reviewed.
Results : From May 2009 to July 2012, 36 patients were assigned to closure using the ADO II. There were 21 females and 15 males. The median age was 16.5 (2-233) months; median weight, 8 (3.94-39.2) kg; and median height, 75 (55-166) cm. The mean pulmonary artery pressure was 24.4 (± 10.4) mmHg, the pulmonary blood flow:systemic blood flow (Qp:Qs) ratio was 2.25 (± 1.97), and mean pulmonary resistance (Rp) was 1.87 (± 1.28) Wood units. The mean ductal size was 2.74 (± 1.3) mm. In 30 patients the device was delivered through the pulmonary artery. Thirty-three patients achieved complete closure by discharge (day one).
Conclusion : The ADO II is capable of closing a wide range of ducts in carefully selected patients. Our findings are comparable with other studies regarding ductal closure rates.
