ABSTRACT
Transcatheter occlusion of the patent ductus arteriosus [PDA] is a minimally invasive treatment. The appropriate device size is chosen based on the angiographic measurement of the PDA. The current study aimed to assess the relationship between the transthoracic echocardiographic [TTE] measurements of the PDA prior to the occlusion procedure and the actual size of the deployed device. We reviewed the available records of 7 patients [2 male] who underwent the procedure at our institution [mean age 21 +/- 12.7years, range 7 to 46years]. PDA closure was performed successfully using the Amplatzer Duct Occluder [n = 5] and its Chinese copycat, Cardi-O-Fix Occluder [n =2]. The TTE measurement of the aortic end diameter of the PDA showed a good linear regression correlation with the size of the implanted duct occluder [duct occluder size = 0.543 + [0.941 x TTE measured diameter], R = 0.907; p value = 0.01]. TTE can provide a good estimation of the size of the Amplatzer duct occlude
