Abstract
PDA is one of the most common congenital heart diseases. A hemodynamically significant PDA in infants has to be closed by either surgery or trans-catheter intervention at any age. Trans-catheter closure of PDA results in marked improvement of clinical and hemodynamic status of the patients. There are many advantages of trans-catheter PDA closure compared toةsurgical ligation which includes; less invasion, no surgical scar, short hospital course and low morbidity with comparable success rate. The trans-catheter closure of PDA has advanced rapidly with improvements in device designs. Coils for smaller ducts and occluders for larger PDA are the devices of choice. With the introduction of the Amplatzer duct occluder (ADO), closur of large PDA has become safer and more effective. The aim of this study was to assess the safety and effectiveness of the cardiac catheterization in closure of patent ductus arteriosus, and to compare between different devices available in Egypt used in trans-catheter closure of PDA regarding the success and possible complications. This study is a prospective one which included 326 patients with PDA, who underwent elective trans-catheter PDA closure, most of them at the cardiac catheterization laboratory of Specialized Children hospitals, Faculty of Medicine, Cairo University and some of them at Tanta University Hospital. The cases were collected from December 2010 to December 2015. All patients were subjected to complete history taking, full clinical examination, chest X-ray, electrocardiography, Doppler echocardiography and laboratory evaluation before they were transferred to the catheterization laboratory for undergoing an attempt of PDA closure.
