[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.

Rare association of anophthalmia, complex congenital heart disease and pulmonary hypertension: case report.

Clinical congenital anophthalmia is described as the uni- or bilateral absence of the eyeball that might occur in isolation or as part of a syndrome. It has a very low prevalence and its etiology is heterogeneous. Complex congenital cardiac malformations are also rare.

[Silver-Russell syndrome (hemihypertrophy) and cor triatriatum in a newborn].

Hemihypertrophy syndrome and cor triatriatum are extremely rare pathologies. Hemihypertrophy is defined as complete or partial overgrowth of one of the hemibodies. Cor triatriatum is a congenital heart disease characterized by a membrane which separates the left atrium into two chambers; if that membrane has a restrictive hole, it causes obstruction to blood passage from the pulmonary veins into the left ventricle causing hypertension and pulmonary edema.

[Intracardiac persistence of pericatheter fibrin sheath in a newborn: case report].

One of the complications related to central venous catheters is the so-called "fibrin sheath or sleeve", the persistence of this structure after central venous catheter removal is uncommon, especially within a cardiac chamber. A neonate with symptoms of infection and portal vein thrombosis with suspected umbilical catheter fragment retained in right atrium was consulted for possible removal by catheterization. Prior to the procedure, the echocardiography findings guided us to the diagnosis of persistent fibrin sheath.

[Percutaneous exclusion of traumatic abdominal aortic pseudoaneurysm from a brachial approach].

Abdominal aortic pseudoaneurysm (AAP) is a rare lesion, although traumatic aortic injury is described as one of the main causes; both the rupture as the surgical treatment of the defect has high morbidity and mortality. Therefore, endovascular treatment either by chemical embolization or exclusion of defect with devices has emerged as an alternative treatment. However, there are risks such as occlusion of visceral vessels near the neck of the defect, embolization material or aortic rupture.

[Double-chambered right ventricle: case series].

The double-chambered right ventricle is a rare congenital heart disease caused by hypertrophic anomalous muscle bands that divide the ventricular cavity, resulting in the formation of a high-pressure proximal chamber and other low-pressure distal one. Because of its evolving nature, its diagnosis is usually made during adolescence or adulthood. While pediatricians see patients whose age range is well established, currently pediatric cardiologists attend patients with cardiopathies from the fetal stage to adulthood, because they are more familiar with these malformations.

Percutaneous closure of patent ductus arteriosus in adults using different devices.

Surgical closure of patent ductus arteriosus in adults involves a number of risks because there are associated anatomic and histologic alterations. Between October 1992 and August 2008, 23 patients were referred to our department with isolated patent ductus arteriosus. Their age ranged from 16-75 years (median 25.

Percutaneous closure of a modified Blalock-Taussig shunt using an amplatzer vascular plug.

Modified Blalock-Taussig shunts are usually clamped during the successive corrective or palliative surgical procedures carried out to treat underlying congenital heart disease, though at times they may be left permeable for a number of reasons. Subsequently, when this is no longer considered necessary and closure is indicated, the method of choice is percutaneous embolization using various coils or other devices. We report on a series of patients in whom this type of shunt was closed successfully via an arterial approach using a new device: the Amplatzer Vascular Plug.

[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.

[Pulsatile Fontan: transcatheter closure of patent pulmonary artery. Follow up mid-term].

Objective: We report the percutaneous closure of the pulmonary artery with residual shunt in patients with Fontan type circuit.

Method: Patients aged 9 and 11 years, with SaO2 of 88 and 96%, respectively. One of them coursing with headaches and functional class II.

[Patent ductus arteriosus closure using a new device: the Nit-Occlud device].

Between May 2003 and July 2006, we carried out percutaneous patent ductus arteriosus closure using a Nit-Occlud device in 28 patients, who had a median age of 1.8 years (range 0.5-21 years) and a median weight of 10.
