Multiple Organ Failure Associated with SARS-CoV-2 Infection in a Child with Down Syndrome: Is Trisomy 21 Associated with an Unfavourable Clinical Course?

Introduction: Down syndrome (DS) is one of the most frequent genomic disorders around the globe (∼1:700 births). During the COVID-19 pandemic, it has been recognized that children with DS are patients with a greater risk of presenting SARS-CoV-2 infection-related poor outcomes. Nonetheless, a few cases with DS and SARS-CoV-2 infection have been reported.

[Lung perfusion studies after percutaneous closure of patent ductus arteriosus using the Amplatzer Duct Occluder in children].

Objective: The closure of patent ductus arteriosus with multiple devices has been associated with a reduction in lung perfusion. We evaluated the pulmonary perfusion after percutaneous closure of patent ductus arteriosus with the Amplatzer Duct Occluder device using perfusion lung scan.

Methods: Thirty patients underwent successful percutaneous patent ductus arteriosus occlusions using the Amplatzer Duct Occluder device were included in this study.

[Percutaneous closure of the patent ductus arteriosus in children with the Amplatzer Duct Occluder II].

Introduction: In the last decades, several devices have been used for the percutaneous closure of patent ductus arteriosus, with its own limitations and risks. The Amplatzer Duct Occluder II has been designed to overcome those limitations and reduce risks.

Objective: We described our initial series of patients who underwent percutaneous closure of patent ductus arteriosus with the Amplatzer Duct Occluder II, emphasis on the technical aspects of the procedure.

[Balloon angioplasty for native aortic coarctation in children younger than 12 months: immediate and medium-term results].

Introduction And Objectives: The use of the balloon angioplasty (BA) in the treatment of patients with native aortic coarctation during childhood, particularly during the first 12 months of age, is controversial. The aim of this study was to report our experience with the use of this therapeutic technique and review the immediate and middle-term results in patients until 12 months age with native aortic coarctation and to identify those factors related with the outcome.

Material And Method: We review retrospectively the clinical records of 35 patients less than 12 months of age with diagnosis of native aortic coarctation who underwent balloon angioplasty as first choice treatment during an eight year span (1998-2005).

[Transcatheter occlusion of the patent ductus arteriosus with detachable coils: immediate results and intermediate-term follow-up].

Objective: To determine the success rate and safety of percutaneous closure of patent ductus arteriosus (PDA) with a detachable coil.

Methods: Forty-one children with small- to moderate-size PDA (maximum diameter < or = 4 mm) underwent percutaneous coil occlusion. The results were assessed by angiography and echocardiography.

[Right coronary artery fistula opening into right ventricle. Echocardiographic findings and interventional management. Report of a case].

Coronary artery fistula is a rare condition in which a communication exists between a coronary artery an a cardiac chamber or systemic vein. It causes an obligatory shunt from the high-pressure coronary artery to a lower-pressure cardiac chamber. We report a case of right coronary artery fistula draining into the right ventricle, echocardiographic features and interventional catheterization.
