[Closure of patent ductus arteriosus with Occlutech device, experience in an andean country].

Background And Objective: To communicate the experience in an Andean country with the OcclutechTM Duct Occluder device for the closure of patent ductus arteriosus.

Method: observational, retrospective, cross-sectional study with basic statistical analysis. Period: December/2014 to December/2022.

[Horn-shaped” deformity of the Occlutech®-PDA device: case report].

Background: The phenomenon of deformation of devices for closure of intracardiac defects in catheterization has been reported, but not of devices for closure of patent ductus arteriosus.

Objective: to report a case of deformation of a relatively new type of device for closure of patent ductus arteriosus.

Methods: report an adult with hypertensive patent ductus arteriosus and a positive balloon occlusion test will be presented, in whom the occlusion was attempted with an Occlutech®-PDA device.

[Chronic wheezing child and type "D" double aortic arch: case report].

Right aortic arch with retroesophageal left innominate artery is an unusual pathology. The presence of patent ductus arteriosus, or left ductal ligament, does complete the vascular ring (Type "D" double aortic arch). In infants with dysphagia, stridor and/ or recurrent wheezing, presence of vascular rings may be suspected.
